v0.9.4

OptiScaler v0.9.4

2 fun milestones - OptiScaler has now passed 1 MILLION downloads and over 9000 stars! 🎉 🎉 🎉

We would like to send our thanks to everyone for the longlasting support!

And now the release info.
This release is focused on adding proper support for FSR 4.1.1/FFX 2.3 SDK which adds INT8 support, albeit officially for RDNA3 only. Please read the notes below on how to force enable it on unsupported GPUs, and how to properly verify it's working (important due to internal checks and a fallback FSR3 mode).
Also a little something for the rare FSR 3.1 users.

Full changelog below.

Always check the Wiki for more information on compatibility, FG options etc!

Caution

• We've been informed about some FAKE websites presenting themselves as OptiScaler team, so we would like to strongly highlight that we DO NOT HAVE an official website!
• We DON'T have an official manager app, so please be careful when downloading or using them! And please don't bother us to provide support for something which isn't even ours!
• Only LEGIT places are this Github, our Discord server and Nitec's NexusMods page.

What comes bundled:

• OptiScaler 0.9.4-final - Signed build
• Fakenvapi 1.4.1
• Nukems dlssg_to_fsr3 0.130
• FFX 2.3 SDK - FSR 4.1.1 (now with official INT8 support), FSR-FG 4.0.1
• XeSS 3.0.1 SDK (upscaler still reads 2.0.2, MFG is still Arc only❗)

What doesn't come bundled :

• FSR 4.0.2c INT8
  • Recommended for RDNA2 Windows users due to the persisting driver compiler regressions!
  • Better luck in early 2027 🥲

---

New and improved MAJOR features in 0.9.4:

Updated to latest FFX 2.3 SDK/FSR4.1.1 (@FakeMichau, @TheRazerMD, @cdozdil)

• Updated model/preset hooking for FSR 4.1.1 (@TheRazerMD, @FakeMichau)
  • Fixes the Failed to hook error on both the Driver and SDK upscaler DLL
• Added FSR 4.1.1 for officially supported cards (@FakeMichau)
  • RDNA 3 desktop GPUs (dGPUs) now have autoenabled Fsr4Update to access the INT8 model
  • RDNA 3/3.5 mobile iGPUs/APUs are not officially supported, neither are other vendors, check below!
• Try to use Int8 on RDNA3 on Linux when possible (@FakeMichau)
• Don't link FSR-FG camera struct if it's just all zeros (@FakeMichau)
  • Should fix an issue where driver upgrade FG would fallback to FSR3-FG when using OptiFG
• ⚠️ Added Fsr4ForceEnableInt8 option for FSR4 incompatible GPUs (@cdozdil) ⚠️
  • Set this option to true to force enable INT8 on unsupported GPUs - such as RDNA 3/3.5 mobile (iGPU/APU), Intel/Nvidia
    • Do not touch the Fsr4Update= option in OptiScaler.ini, as setting it true on unsupported GPUs will autofallback to FSR3!
    • This does not mean old GPUs (which don't support INT8) will work!
    • Only applies to the shipped SDK upscaler DLL, won't affect the Driver amdxcffx64.dll!
  • RDNA2 Windows users are recommended to continue using FSR 4.0.2c as the driver compiler regression (which causes ghosting etc) is yet to be fixed!

❗IMPORTANT REGARDING FSR4.1.1 INT8❗

• With FSR 4.1.1, along with adding INT8 support, AMD has also added internal checks for GPU validation and currently only RDNA4 (FP8) and RDNA3 dGPUs (desktop, INT8) are officially supported
• All unsupported GPUs fall back to the internal FSR3 upscaler!
  • Due to the above, it's very important to check the FSR4 Upscaler Watermark reporting (FSR4, FSR4-i8 or FSR3)
    • Either enable the Watermark under the Upscaler selection or by setting Fsr4EnableWatermark=true in OptiScaler.ini
  • We've added possible FSR3 fallback detection when upgrading to 4.1.1 on unsupported GPUs, but the Watermark still remains the most accurate confirmation.

---

• BAT improvements (@TheRazerMD)
  • Improved faulty setup detections, added more info, reorganised some parts
  • Should now work in folders with special characters and be more foolproof in general hopefully
• Added FSR3.1 tuning presets (@cdozdil, thanks to Weather)
  • Bit of community sourced info that may or may not help FSR3.1 image quality
• Tweaked FSR4 settings and the Opti overlay in general (@FakeMichau, @TheRazerMD)
  • Made some options into a dropdown menu, added FSR3 fallback detection (for FSR 4.1.1 upgrade)
• Show FSR3.X/4 in Opti Overlay when using 4.1.1 and above SDK dll with ForceInt8 (@cdozdil)
  • Should now show FSR 3.X/4 instead of just FSR3.X when INT8 is forced

Note

Regarding FSR4 VK w/Dx12 on Linux

• Proton 11 adds the missing required Wine extensions, VK w/Dx12 should be working now, but needs more testing and might require extra bugfixes down the line
• RADV may have a massive performance drop compared to AMDVLK (unrelated to OptiScaler) - Mesa issue link

---

New and improved minor features in 0.9.4 include:

• Fix FSR3.1 presets dynamic calculation (@cdozdil)
• Fix for Typeless Hudless resourcess (@cdozdil)

• FSR4-FG requires Mesa 25.2+ and Wine prefix set to Win 11 (per-game, if global config isn't working)

v0.9.3

OptiScaler v0.9.3

This release is mostly focused on fixing issues that popped up with the 0.9 releases (such as ResizeBuffers1 crashes), alongside some improvements to the Overlay's HDR tonemapping, swapchain backbuffers, fixing RTX Remix crash etc.

Noteworthy new feature is the addition of Manual Input Polling which fixes the invisible Opti Overlay in games such as Metro EE, STALKER Trilogy remasters, DL2, DLTB.

v0.9

OptiScaler v0.9

April Foo...

No, wait, almost forgot, this isn't an April Fools joke, that was a close one. What we wanted to say was...
We're back with a new Stable build after 7 months of massive feature creep, prolonged testing and multiple delays (kinda like the AAA game industry, atleast regarding the last part).

Kept you waiting, huh?

❗Our biggest release so far,❗so don't be surprised by the chungus changelog

Lots of people have been asking us over time about supporting the project, and we're finally happy to say that's now possible! Also linked in the Readme

• BMAC ☕
• Github Sponsors ♥️

Caution

• We've been informed about some FAKE websites presenting themselves as OptiScaler team, so we would like to strongly highlight that we DO NOT HAVE an official website!
• We DON'T have an official manager app, so please be careful when downloading or using them!
• Only LEGIT places are this Github, our Discord server and Nitec's NexusMods page.
• OptiScaler is FREE, any kind of monetary requirements are scams!

Warning

VERY IMPORTANT!

• While the new BAT should automatically display a warning if you're updating from an existing Opti 0.7.9 install, we would still recommend deleting old OptiScaler using the uninstall BAT and manually deleting Fakenvapi's old nvapi64.dll if present in the folder.
• Linux users will need to manually remove nvapi64.dll (and probably nvngx.dll if present) along with any old Opti version!
• Necessary step to ensure everything works properly since OptiScaler now comes bundled with Fakenvapi (renamed to fakenvapi.dll)

---

What comes bundled:

• OptiScaler 0.9-final - Signed build
• Fakenvapi 1.4
• Nukems dlssg_to_fsr3 0.130
• FFX 2.2 SDK - FSR 4.1, FSR-FG 4.0.0
• XeSS 3 SDK (upscaler still reads 2.0.2, MFG is still Arc only❗)

What doesn't come bundled:

• FSR4 INT8
  • which is required for any other non-RDNA4 card!

---

New and improved MAJOR features in 0.9:

• FG settings received a major rewrite/revamp - added XeFG (+XeLL), Redstone FSR4-FG, separated options into FG Sources and Outputs, added shortcut etc (a big part thanks to @FakeMichau, also @cdozdil)
  • Added enable/disable FG shortcut key - default is End (customisable, Keybinds in Overlay, FGShortcutKey in INI)
  • Some options aren't supported and may be implemented down the line (e.g. XeFG as FG Source, DLSSG as FG Output)
  • HUDless logic improved
  • OptiScaler now comes bundled with latest Fakenvapi (1.4) and Nukems dlssg-to-fsr3 (0.130)
  • FG Inputs (game FG inputs AKA what you select in the game) and FG Outputs (what you want to use through Opti) - you need to select both now
    • DLSSG via SL FG Input is recommended, then FSR-FG then OptiFG/Upscaler as a final resort
  • All of these options explained more in the Wiki in Frame Generation Options

Click here to see the list of FG Inputs

• DLSSG via Streamline inputs (only DX12 and Streamline 2+ games, doesn't support a small number of old SL1 games, tooltip warns about unsupported version)
  • Required to enable DLSS-FG in the game and then tick (FG) Active in Opti's overlay
  • This is our own equivalent of Nukem's mod which is a lot more versatile, albeit a bit less (legacy) compatible as noted
• Nukem's DLSSG is locked to FSR3.1 FG as that's the only option (Nukem's DLSSG -> FSR3-FG via Nukem's)
  • Also requires DLSS-FG activated in-game
• OptiFG (Upscaler) now also supports XeFG, in addition to FSR3/4-FG
  • OptiFG is without the HUDless resource, but unlike FSR3 FG, XeFG/FSR4-FG does interpolate the HUD variably well (might not even require HUDfix), while FSR3-FG requires HUDfix always
• FSR 3.1/FSR3.0 FG Sources
  • Also a new addition for games that have native FSR3.1/FSR3.0 FG, can be a bit finnicky
  • Requires FSR-FG enabled in game settings

---

• Updated to XeSS 3.0 SDK (@cdozdil) - yellow XeFG restart text must be followed, otherwise ghosting will be noticeable
  • XeFG doesn't work in exclusive fullscreen. Requires using Borderless Windowed/Borderless Fullscreen/Fullscreen Windowed!
  • Due to how XeFG works, you might need to activate XeFG once and then restart the game for all settings to apply - hence the yellow warning text.
  • Do not use RTSS with Reflex markers injection when using XeFG!
    • For optimal compatibility, also enable Use MS Detours API hooking in RTSS Setup/Settings
  • All XeFG requirements/limitations explained more in the Wiki in Frame Generation Options
  • MFG support officially added (still Arc only❗)
  • Now able to change interpolated frame count on the fly
    • freezes between 2x <-> 3x/4x are expected
  • Extra XeFG checks to prevent crashes with older binaries
• Added XeFG UI Composition option
  • Enabling this option reverts XeFG to previous XeFG 2.0 behaviour where it doesn't try interpolating the HUD - fixes artifacting for transparent HUDs

---

• Updated to FFX 2.2 SDK (big part thanks to @FakeMichau, also @cdozdil) - FSR 4.1 upscaler, FSR-FG 4.0.0 (ML-FG) (RDNA4 only!!!)
  • 4.0.0 ML-FG doesn't work with Nukems, as that mod only uses FSR3-FG!
    • All of the FSR Redstone features officially support only RDNA4, so unless you're willing to use Linux with FP8-to-FP16 emulation (or AMD decides otherwise), supporting other gens isn't happening. FSR4 INT8 upscaler (4.0.2) is the only version prior gens can use, and you'll have to find it yourself, Opti does not ship it.
  • Switching between FSR3-FG and FSR4-FG is possible while FG is active
  • Fixed model selection on FSR 4.0.3 and FSR 4.1 (thanks to @FakeMichau and @TheRazerMD)
  • Added FSR4 Debug options (@cdozdil) - FSR4 Debug view and FSR4 Watermark (Watermark requires game restart, thanks to @Astyyyyy for fixed WM) as well as FSR4-FG Watermark debug option (MLFI)
  • Updated FG and FSR4 model menu displays (@TheRazerMD)
    • Should make it more clear which FG settings to (not) use for FSR4-FG and what the models represent

• Added FSR4 Vulkan w/Dx12 support (@cdozdil) – FSR3.x/4 VK w/Dx12, as well as FSR 2.1 VK w/Dx12
  • This enables using FSR4 on Vulkan games - works through the DX12 interop, thus the upscaler cost will be noticeably higher
  • IMPORTANT - Linux currently doesn't support FSR3.X/4 VK w/Dx12 due to missing some needed extensions.
• Added RCAS and Output Scaling to Vulkan upscalers (@cdozdil)
• Also updated all downscalers for Output Scaling (@cdozdil)
  • Sharper Bicubic, added Lanczos 2 & 3, added Kaiser 2 & 3
• Added missing Vulkan hooks (@FakeMichau)
  • This fixed NMS VR crash

---

• Added separate Non-Linear Color Space option for FSR4 (@cdozdil)
• Quirks reorganising and support improvement (@TheRazerMD)
  • WinGDK versions should now also be supported if they stick to the regular filenames
  • Various game quirks added for a better out-of-the-box experience
• General BAT improvements and updated Uninstaller scripts to remove additional files, along with old Opti versions, and unused files (nvapi64.dll etc) (@TheRazerMD)
  • Also added OptiPatcher support to the BAT (thanks to @realdody for the initial commit, and @TheRazerMD for bugfixing and improving afterwards)
  • Another side project of ours - OptiPatcher - an ASI Plugin for OptiScaler for exposing DLSS and DLSS-FG inputs without adapter spoofing in supported games and avoiding any kind of performance overhead.
• OptiFG improvements (@cdozdil)
  • Should stop The Callisto Protocol from crashing with its special heaps spamming
  • CPU usage should now also be reduced
• Removed DlssOverrides folder (@cdozdil)
  • Reg files weren't required for a long time now and have already been integrated into Opti itself
• Autoapplying fixes and quirks for Luma Unreal Engine mod (@cdozdil)
  • Luma UE should now be working properly without any editing (check the Compatibility Entry for preferred method of loading, also the FSR4 list for confirmed working games so far)
  • Should also work fine for Win 10 users (FSR4 still requires AgilitySDK upgrade on Win 10)
• Added VRR FPS limit calculator under Framerate tab to select an optimal framecap (@cdozdil, also @FakeMichau)
• Added Active Quirks info to overlay menus (@cdozdil)
• Allow auto option for menu scale, as well as saving of menu scale 1.0 (@cdozdil)
  • Helps games that cycle from Windowed to Fullscreen on boot and mess with Opti (e.g. MH Wilds)
• Added FSR2 DX11 input support (@cdozdil) - e.g. Trails in the Sky 1st Chapter
• Added FSR2 Vulkan input support (@cdozdil) - e.g. WWZ
• Separated DLSS/DLSSD preset overrides, also added ability to revert back to game's original preset (@cdozdil)
• Added XeSS DX11 inputs (@cdozdil)
• Added Process Filter option (thanks to Schmidts) ...

0.7 Old Nightly Builds

This build is older than the v0.7.9 release

Changes since 0.7.7-pre9

It's been a while since we've uploaded a public build (2 months now), thanks to a lot happening in the meantime. Lots of code revamping, HUDfix overhauls, FSR4 improvements, UI changes, new features, jobs being busier than usual etc.

Since it incorporates a lot of fixes and additions, we haven't yet been able to test it properly for a Stable 0.7.8 release, things might've fallen through the cracks, so please report if there are new issues.

Important

• With this build and onwards, selecting Yes to DLSS Inputs (as AMD/Intel) no longer creates a nvngx.dll, since @FakeMichau managed to workaround that.
• Now only selecting No to DLSS Inputs should modify Optiscaler.ini and change Dxgi=auto to Dxgi=false.

Note

Despite major improvements, HUDfix is still an experimental WIP and might not be stable.

Fixes since initial nightly upload

v0.7.9

OptiScaler v0.7.9 (Evergreen)

Caution

• We've been informed about some FAKE websites presenting themselves as OptiScaler team, so we would like to strongly highlight that we DO NOT HAVE an official website!
• Only LEGIT places are this Github, our Discord server and Nitec's NexusMods page.
• OptiScaler is FREE, any kind of monetary requirements are scams as we don't even have a donation link at the moment!

We also have another side project - OptiPatcher - an ASI Plugin for OptiScaler to expose DLSS and DLSS-FG inputs without spoofing in supported games.

Important

• From 0.7.8, selecting Yes to DLSS Inputs (as AMD/Intel) no longer creates a nvngx.dll, since @FakeMichau managed to workaround that. One less step required now if you were doing it manually.
• Now only selecting No to DLSS Inputs should modify Optiscaler.ini and change Dxgi=auto to Dxgi=false.

Nothing big in this update, just some welcomed improvements and fixes.

• Fixed menu rendering under Vulkan (thanks to @cooltyp100) - should finally fix the long standing black screen bug when Opti overlay open for our Linux users
• Splash screen updates
• Added support for FidelityFX SDK 2.0.0 and FSR 4.0.2/3.1.5 (@cdozdil) - renamed the loader file, should work from our testing, Upscaler DLL now contains FSR 4.0.2, had to bundle the unsigned DLLs because some games didn't like the signed ones for RDNA4 specifically
• Fix FSR4 model selection with the new FFX SDK (@FakeMichau)
• Hopefully fixed NMS crashes (@FakeMichau)
• More game quirks added (@TheRazerMD)
• Added OptiPatcher info to menu when patching successful (@cdozdil) - shows (OP) in the overlay title
• Fixed Overlay visual glitching (@FakeMichau)

Note

Edit: Linux bois need the new Proton-EM 10.0-2D or any other newer which supports FSR 4.0.2/FFX SDK 2.0.0 in order to work

v0.7.8

OptiScaler v0.7.8 (Typeless)

Whoa, it's been almost 4 months since last Stable release? Damn, time does really fly.
Loads has happened in the meantime, and after loooots of code revamping and overhauls and Nightly testings (many thanks to everyone who helped testing!), we're finally ready for 0.7.8 😎

There's a chungus amount of changes, so we'll let the release notes talk for themselves! And no, there's no XeFG DP4a here...yet

We also have another side project - OptiPatcher - an ASI Plugin for OptiScaler to expose DLSS inputs without spoofing in supported games (if you need NukemFG on UE games, that still requires spoofing sadly, for non-UE games, Michau's SL Spoof is pretty successful in unlocking all options).

Caution

• We've been informed about some FAKE websites presenting themselves as OptiScaler team, so we would like to strongly highlight that we DO NOT HAVE an official website!
• Only LEGIT places are this Github, our Discord server and Nitec's NexusMods page.

Regarding FSR4 models

As best as we can see, models seem to correlate to quality/rendering presets. Internally, AMD seems to be using Model 0 for Native AA, Model 1 for Quality, 2 for Balanced, 3 for Performance. Models 4 and 5 not exactly sure, but 5 should be for UP. Unlike the other models, Model 1 seems to have a bit inconsistent deadzone around ratios, thus in some games Quality actually gets redirected to Model 0 which causes the shimmering noticed in Oblivion and STALKER 2. Hence the reason Optiscaler is always forcing Model 1 for Quality and UQ. AMD know about this issue and will be fixing it in a future update. And to try explaining the model numbers, maybe each higher model has more accumulation history, which would explain why Model 0 is the sharpest (and meant for Native AA), and e.g. Model 2 is blurrier, but also more stable in games (as Balanced) which were forcing Model 0 (instead of 1) on Quality and causing shimmering.

v0.7.7-pre9

OptiScaler v0.7.7-pre9 (Daria)

Recently, I have been refactoring OptiScaler a bit, and it looks like I moved a lot of code, which caused numerous compatibility issues and bugs. Thanks to @TheRazerMD’s continuous support, we have (hopefully) resolved all of the issues. There may still be some edge cases we missed; please report them with logs as usual.

OptiFG is basically a hack, and Hudfix is pushing it even further. We’re aware of its compatibility issues (and crashes). I can’t guarantee I’ll fix all of them, but I will revisit OptiFG soon. Meanwhile, I suggest using Nukem’s mod for any games that support DLSS-G.
