Splinter Cell: Double Agent - Widescreen fix broke some shadow buffered lights

[Joris-truly]

Some buffered shadowed lights are completely broken with the widescreen fix. I say 'some' because some point lights render perfectly fine. I guess that's why gone unnoticed for most. (i'm aware it's already a messed up port as it is)

I tested this on two different GPU (Nvidia GTX 1080, and Intel laptop GPU)

Captured some examples:

WITH FIX

WITHOUT FIX

WITHOUT FIX

WITH FIX - As an example to show some lights still work fine

I already tried a lot of fixes found on PCGW (such as tweaking the .INI, and using DGVoodoo2), but deleting the fix is the thing that actually fixed the lighting, haha.

Strange, can you also check if some particular option affects this?

[Joris-truly]

I've tried lowering the resolution to default, using the fix. Didn't work.
Even more artifacting fun: In the area in the first screenshots, using the fix on my Intel GPU does shows the light/shadows a bit, but on the wrong side of the wall and upside down. I'll get a screenshot for you.

I meant these options: https://github.com/ThirteenAG/WidescreenFixesPack/blob/master/data/SplinterCellDoubleAgent.WidescreenFix/SCDA-Offline/System/scripts/SplinterCellDoubleAgent.WidescreenFix.ini#L7-L8

[Joris-truly]

Yes, i meant those options. I worded it badly, sorry. I lowered those values to the default state. Didn't work

[ThirteenAG]

I don't know if I can launch the game right now, but I'll try to check it out.

[Joris-truly]

You'll notice it in the first level immediately (when you're out the water). That light hitting the fench is missing, but the one by the sleeping bunk is fine.

I used this Xbox360 version for compassion. Checking how it's supposed to look

How it looks on Intel, with the fix.

So that little blob shadow is Sam projected upside down. really weird haha

[ThirteenAG]

Unfortunately I can't reproduce. The game looks like on your screens "without fix" for me.

[ThirteenAG]

Hmm, actually nevermind, I think I can reproduce, just in fewer areas.

[Joris-truly]

That's really strange. You using a AMD GPU by any chance?

[Joris-truly]

Yeah, like i mentioned above, some lights are fine, but some others aren't.

Usually those lights that are broken often are placed in spots that 'shine trough thing'. Like grates or windows. In the criminal area (not sure how it's called) you'll notice a lot of lights are obviously missing.

Example for shadow through grate: https://youtu.be/J5-SS8MHF_s?t=2289
This one is also missing with the fix.

I'm usually a stickler for dynamic lighting and shadows in games, so I notice it quickly when it looks off haha. I know a few more places where it's broken. Let me know if you need more screenshots.

[ThirteenAG]

Are you sure you tried to set both ShadowMapResolution and GlowResolution to 0? I think one of those is responsible.

[Joris-truly]

I tried ShadowMapResolution, setting it to it's default (1024). Didn't work. I didn't mess with GlowResolution.

I'll try messing around a bit, and let you know.

[ThirteenAG]

Setting it to 1024 doesn't make it use default code that processes it. ShadowMapResolution = 0 will avoid that issue. I guess either I implemented it wrong from #725, or the presented solution is not perfect.

[Joris-truly]

check, Testing it now. (both maxed out, and setting it to 0)
