Thanks for making this. It is amazing. It's working well on the games I tried except for RE9. The new build allows NR to run without crashing. However, it doesn't seem to be working properly. NR is definitely activating, but there is hardly any change to the image. |
|
Uhm not the first time i heard RE9 is acting weird. I'll look into it |
|
If you aren't sure its doing much, btw. You can always test it with the side by side view : |
|
Thanks. Can’t tell you how much I appreciate what you’re doing. Those of us on VR have no way to enable dlss5 through reshade. Going through Optiscaler is just a fantastic solution!

Hi, i can confirm it is working on my rtx 4060 mobile and was able to gain 60 fps in cyberpunk and gta 5 enhanced with NVE mod. Its amazing. But I don't know its a placebo or because of high fps . The difference doesn't seem to come out as much as how native renodx addon blended the whole system image. Like there is just slight difference even on 100% working resolution and I can't seem to figure out what setting is different but again i suspect if its just my placebo since i was getting about 30-40 fps before , a "cinematic" experience and blended the image compared to 50-60 FPS i get now |
|
Hi, I managed to get it to work just as well during the day as at night with this version with Renodx, but the performance is much worse. Maybe you could take a look or collaborate with him to figure out how to fix it. The image is flawless this time all the time with Renodx and this version of the addon, but the fps really suffer. |
|
Hey, thank you for the follow up, have you tried the latest verison. My suspiscion is thta this game might not expose the texture of the exposure to the upscaler, one way to be sure is open the dropdown of the whitepoint and set it to "Games"s own", if it stays orange then i have something ready for this release, evntually it will be automated but right now what you have to do is wlak a bit until in the game workd then select "Buffer" and clcik on "Anchor". you can set the hud to see the light circle on top, baically it indicates what is the brightst and darkest point the buffer has seen yet, as you have maybe noticed you can set multiple anchors because a tonemap is usally not linear so the idea is if you find a new darkest place or brightest, open the menu and hit "Anchor". You could also do it only when you start to notice issues with the image if you find it easier. Hope that helps, and sorry for the complexity, I am aiming at automatic all that very soon |
|
One thing I should add: whether you have a game that accepts the "game's own" or you set Anchor points through the buffer, you always have a trim option; it's useful if you feel the whitepoint chosen still needs some slight adjustment. And if I didn't mention it before, yes, these are white points, the same kind as the manually set one, but they move as you play for accurate results. "Game's own" is the truth the upscaler is given by the texture of the exposure, whereas "Buffer" is an approximation we try to create by constantly measuring the difference between frames. Also, to add more details, the trim acts as a multiplier over the value given; 1x is the default for the trim, but you can adjust it depending on your liking. Of course, if set to "Buffers" you can adjust every single Anchor point individually by clicking on its row. The manual whitepoint path still exists, mainly as a fallback. |
|
Oh and your intuition was right, i am struggling with colors send help :D. I think the changes i am making are going in the righ direction but no denying it is a bit of a workaround rather than what I'd call a proper architecture. Although most things are like this anyways lol. The only proper path i figured out for now is really the exposure texture but turns out some games are finnicky about it. |
|
Hi, I think I managed to get the anchors working, but it was quite a struggle. Also, when I switch from the interface that displays, for example, the game map, and then go back to the game, or when I start a game, the automatic paper white adjustment takes some time and isn’t active immediately. Also, the values seem strange to me. KCD2 must be sending some weird data because in very low brightness I had to set it to 0.01, then in medium brightness increase it to around 0.6, and then in very high brightness lower it back down to 0.03. That doesn’t make sense. |
|
I used NR in enough games now to be able to pick up when it is working. Optiscaler DLSSNR is working as expected with other games, but there’s something definitely wrong with RE9. The environmental lighting shifts, but none of the characteristic detail and shading occurs in faces.

Is there a way to put a hotkey to enable and disable NR? In star wars zero company when you try to make an overwatch the game crashes, so instead of INS and untick NR I thought if it was possible to create a hotkey like the reshade one |
|
yes, check the "keybinds" menu in optiscaler |
|
Ty man |
|
Thanks for the latest version as of 02/09/26, I happened upon it within moments of you releasing it, so just a quick one to confirm everything is working very well so far, in 1666 Amsterdam at least. you are a star! RTX4090 |
|
First of all Thanks alot for taking your time to give us a Vram Leak free option to use DLSS5 . It performs way better then ReShade for me , there is just one thing , the " Skin Structure " slider doesnt do anything in WWM. 
|
|
Okey that makes sense , thats how it behaves right now , isnt it ppossible that Skin Structure negates the effect on the face if put to 0 ? |
|
yeah, you can try Local structure 2.00, Skin structure 0.00 to sharpen everything except skin, if you didn't try it before |
|
that was the second picture i sent you ^^" Skin Structure doesnt negate Local Structure effect on skin , that was my issue + it doesnt morph ^^ |
|
uhm goign thru the screenshots and i didn't see one with skin structure set to 0 and local set to something else tho |
|
nvm i see your issue, will be addressed. trying it out in cp2077 rn. Thank you for pointing it out, mbd for the drawn out process |
|
Thank you for this! I'm using it for inserting DLSS 5 into Unreal Engine editor. There is just one thing it fails against Reshade option: when closing the project, it shows a crash screen: Fatal error! Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000014 0x00007ff9cd552f64 _nvngx.dll!UnknownFunction [] Unhandled Exception: EXCEPTION_ACCESS_VIOLATION writing address 0x0000000000000014 _nvngx |
|
Will take a look at it |
|
Thank you @Dagherbou ! Let me know if you need me to test again, or if you think you found anything. Thank you! |
|
where i can find nvngx_dlssnr.dll ? |
|
Check the official RenoXD Discord, other sources could have malware. |
|
Is there a way to take before/after screenshots like with the reshade mod? |
|
You have the comparison view, you can choose side by side or swipe and you can add labels with a toggle. No screenshot button as of right now but I believe the comparison view simplifies it more if you're looking at an on/off comparison. Especially the swipe. |
|
Can someone explain how the Model Resolution scaling work? Is it using DLSS 4.5 to upscale the image or some other filter. |
|
very basic, model runs at a reduced resolution, then its edit is stretched back to display resolution with plain bilinear filtering. So like no fancy sr used. The downsample into the model is better (exact-area box, so the whole footprint). I did test a dedicated sr pass to the nr, it didn't go well but i also didn't try to work on it, so might come back at some point. Focusing on a stability work first tho Worth mentioning, my sr pass on the nr never actually was in any of the releases, only internal testing and some public releases that were done before the project went on GitHub |
|
Is sr pass on nr feasible on the performance side? How comparable were your results with sr on nr vs simple stretch |
|
The issue with sr on nr is matching the colormapping and managing the extra noise it generated somehow. But I will look more into it a bit later, I am finishing up the last touches for a new release then going to sleep for the next 12 hours. I will give you more info when i do, dw i'll keep you updated |
|
Thanks a lot man, respect to your work. Prioritise your sleep, we can wait |
33.mp4https://github.com/user-attachments/assets/0bffbbdc-313c-4e53-ad7e-4d151cb9974e To make it more visible and isolate other variables, the video was captured using local structure = 2, Natural Style, local tone = 2, and model output (raw). This flickering seems to stem from poor temporal consistency—I suspect motion vectors might not be utilized properly by the model. I’ve observed this behavior in both your project and the RenoDX addon. Or could this be due to incomplete support for the RTX 40-series DLL? |
|
The video demonstrates the behavior at both full resolution and 33% resolution scale. The flickering is much more pronounced at lower scaling factors, but it can still be observed at full resolution as well. |
|
thank you, i'll take a look. Keep in mind i am on 50 series so if its really the dll i won't be able to replicate it |
|
This seems to be a combined issue of downsampling and luminance mapping. The visual noise and the 'sliding' sensation in the shadows likely originate from imperfect tone mapping and downsampling, respectively. |
|
Hi, when i put OptiScaler in Cyberpunk 2077, ray reconstruction parameter gets disabled. What's the problem? |
|
okay, i need time |
|
Is the file generated only when the game crashes? Because it's not in my folder |
|
I have found how to log |
|
II sent the file in the issues thread. |
|
perfect |
|
Is adding RTX40MFG possible? |
|
I have successfully implemented DLSS Neural Rendering effects by loading the Reshade DLSS MOD for DX11 Assassin's Creed Origins together with [OptiScaler_DLSSNR]. However, I had to replace the DLSS upscaler in the middle with FSR3 w/Dx12 as a workaround. This raises the question: What prevents DLSS w/Dx12 from being implemented? Given that DLSS NR (Neural Rendering) and DLSS FG (Frame Generation) are both DX12-exclusive features that successfully work as post-processing passes on DX11 games, it seems technically feasible for DLSS upscaler to be bridged through a background DX12 device in the same manner as FSR and XeSS currently are. Is this a technical limitation issue or a matter of implementation priority/willingness from the main branch? |
|
Well you are in luck, you can get from the repo the mostly up-to-date work. I fixed the bridge, now you can use DLSS over it. |
|
You also have the choice now between the fixed native Vulkan implementation or the bridged one. Stick with the native tho, the resolution slider bug has been fixed. Like i said do not get the release, get the files straight from the repo. I have not packaged the final release yet. I still have some fixes to implement. |
|
Hi alensakura, can you explain what you did and how is it different from dlss feeder? Is using optiscaler on dx11 bridge produces better results. Can you explain more, i am interested |
|
Indiana Jones is crashing if I turn on Ray Reconstruction. |
|
Please try to download form the repo directly, I think its fixed. Let me know how it goes |
|
As of for the release, it will come at a a later date when the update will be complete |
|
BTW, have you seen this similar OptiScaler? Would you mind pointing any difference with yours? Thank you! |
|
any chance of RTX A1000 ADA Gen 6GB support? |
|
Honestly, thanks for all you’re doing.
Have a great sleep!

Since this is the most performant and optimized mod for DLSS5 , do u think u still update it in the near future or keep it as it is ^^? |
|
updates will continue to flow, i have a lot to do. A release is gonna drop in the next 30 minutes for e.g. Will bring a lot of improvements |
|
Damn looking forward to it. Also i saw in renodx addon with work resolution slider,they are using fsr 1 on the nr model output to scale it back up. Can it work here? |
|
I am using in the new build the same technique to scale it back down (so if you got the headroom you can have sharper and cleaner visual and you can even combine it with Output Scaling). The scaler to the way up is still not using these more advanced spatial upscalers, that's gonna be a patch soon. This release is mainly focused on parity between all three APIs so dx11, dx12, and vulkan, then additional color improvements with i think some lever tricks (might need to read the changelog to get the gist of it), UI improvements and general quality improvement by the introduction of different proxy (the image the model actually uses to synthetize its details), the default one i was using was good but a bit blown out which generally brought a bit less detail then RenoDX's, now i have 4 including the default, you can set what works best for you. Also a bit random but i added a way to hold a frame so if you wanna compare without movement on screen you can, a bit noisy will be improved in future patches. Expect next releases to be more like patches thus faster cycle, bigger releases will sill happen but I’ll keep pushing fixes instead of racking them up |
|
Great man, looking forward to the next release |
|
i have a problem that only happens with this optiscaler version where i cant close the optiscaler window because it pops up again and i cant click any of the buttons on it, does anybody know what it might be? Video.Project.1.mp4 |
|
Okay i am sorry its totally on me then, i was hoping it wouldn't be :). basically i fixed an issue where a key would remain held when opening the menu but I misut've either set 0ms debounce window or set it on down instead of up. My rought guess is you have a fast polling rate keyboard right ? Must be because of that, give me a sec |
|
maybe it is that |
|
So i am sorry it took some time, i was thinking about the best way to deal with this since rn i am not on my main system so i don't have the runtime and the toolchain to propely recompile. My main tree has these fixes embedded, I'll patch that as soon as i can. I modified a line in this release. That should stop it from runnign my "fixes" but the menu also dosen't stop the game from answering to your input this time so there's that drawback until I am able to do it properly. Here's the temporary file : https://wormhole.app/l86ddR#0Ulq5MZmxhDSx3U-iy4GQA |
|
Let me know how it goes, sorry for this fairly unecessary inconvenient. |
|
i tried it and it solved the issue for other games but not for asseto corsa so it has to be something related to the game itself |
|
Is there an option to choose whether DLSS NR is using the input or output resolution of DLSS SR? |
|
There isn't |
|
Hello, Quick question, what’s the best way to update to the new version? Should I delete the old build first then install the new one, or just overwrite the existing files? I’d like to keep my custom settings if possible and make the update as simple as I can. Thanks. |
|
Copy all he new files except the .ini if you would like to keep your current settings. then run the .bat it will detect your existent version, ask you if you want to delete the leftovers (you need say yes) and then it will flow back into the usual install |
|
OK, thanks! |
|
Has anyone managed to configure NR for Dragon’s Dogma 2? The game crashes on launch. |
|
Could you please send logs |
|
Optiscaler.log and the game's dump |
|
It stopped crashing when launching. Now it crashes when trying to enable NR. |
|
Awesome will take a look |
|
Hello. Did you manage to find out anything? |
|
Hi, if i am updating, do i have to completely remove optiscaler by using "remove optiscaler" file everytime or is there any way to retain the optiscaler config? |
|
Hi ! I noticed that NR can have pretty big quality differences depending on the environment/scene in some games. |
|
I tried to do this in kcd2 for the dark scenes. You have to use the anchor to set an automatic paper white but it's really difficult in a game like kcd2. Try it with multiple anchor light and dark scenes |
|
Welle I played around with Detail Strength and White Point a bit and found a setup I’m pretty happy with in most environments. I’m still not getting the full NR detail but it definitely improves the overall look of the game. |
|
Got this error in every games except spiderman 2... |
|
Not sure if anyone else is seeing this, but in Cyberpunk, if I enable Frame Generation either in the game itself or through the NVIDIA driver 616.56 (not OptiScaler FG), OptiScaler/NR crashes after toggling Neural Rendering on/off a few times. Most of the time it actually happens on the first on/off cycle. Everything is otherwise vanilla. I've tested after DDU + a clean driver install, and it happens with raster, path tracing, Ray Reconstruction, etc. If I start the game with NR already enabled, I can also trigger the crash by playing with the render scale slider. The reported device removal is a GPU page fault. I've enabled DRED as well, but unfortunately it isn't reporting anything useful beyond that. I may eventually file a proper bug report with logs and the testing I've done, but since the project may not be actively maintained for a while, I wanted to at least document the issue here in case anyone else runs into it or picks up development in a fork. |
Hello, i have an issue with new nvidia drivers. the multi frame gen with input optifg and output dlss on a game that does not natively support the multi frame gen (kcd2) worked before the update of the latest nvidia drivers and now as soon as I put output dlss in v10 the game crashes at startup. For it to work again I had to go back to the old nvidia 610.88 drivers. It's the new nvidia drivers that make it no longer work. (I'm using the latest streamline 2.12.0 and the latest nvngx NVIDIA DLSS DLL 310.7.129) |
|
This is a game specific issue i think, i tried multiple optiscaler builds with NR and it only happens with cyberpunk with toggling NR, and what I observed is the higher multiplier you have for FG, the more likely or sooner it will crash with toggling. Like i have rtx 4060 and with 2x frame gen, it crashes if i toggle multiple times quickly and with ada fg unlock mod, it crashes immediately after toggling in 6x frame gen. For now ig we just have to settle on keeping it on with the settings we like. Also I don't think dagerbhou will update this build since he already said his uni is starting and other devs have already forked his build and are working on further updates. Check renodx dlss5 forums you will see multiple threads there about other build. The one i am using is from wils2jo or something I don't remember |
Yeah, that sounds exactly like what I'm seeing, so it's clearly not specific to my 5070 Ti or installation. The higher FG multiplier making it worse is interesting. DRED reports the device removal as a GPU page fault. I also tested increasing the NR descriptor/constant-buffer ring from 48 to 512 slots, and it still crashed long before the ring could wrap. I'm glad this is now documented publicly. FG in Cyberpunk works fine with RenoDX, and I can't wait until the NR cost slider is implemented in the mainline mod. I'm still really curious about what's actually wrong in this code, though. |
|
I am not as technical as you but i am glad i am not the only one observing this |
Uh oh!
There was an error while loading. Please reload this page.
Hello everyone !
You can discuss anything related to OptiScaler + DLSSNR here. You can share questions, setups and results.
A few rules to respect :
* nvngx_dlssnr.dll is not provided here and requests for it won't be answered
* This is a fork focused on Neural Rendering. Core OptiScaler bugs belong upstream at optiscaler/OptiScaler
* For any clear and reproducible bug, please use Issues, and do not forget to attach your OptiScaler.log
Thank you for giving this way of integrating NR a shot !
