Hm... This fix actually makes game to run ~30% worse... With SLI enabled I now can see proper 3D, but I'm getting merely 70 FPS. With SLI disabled I'm getting 110+ FPS on the very same spot (settings are identical). :/
[b]P.S.[/b] Please, don't think that I'm pushing you in any way :) If you just say that there is NO SLI support and will NOT be any - so be it. I will stick to single GPU and try to find suitable settings. ;)

u have problems with SLI cuz u are probably runing SLI in 8x/8x PCIe mode, DOOM is very bandwidth hungry, for optimal and normal SLI scaling u need to run DOOM in 16x/16x PCIe Mode, max two-way SLI. otherwise lots of negative scalling due to shadows limiting pcie bandwitdh, thats why we need to wait, @TiagoSousa(idSoftware) said on twitter that SLI-support is coming, prolly they will optimise shadows for 8x/8x with Vulkan

Interesting...
Maybe is what EvilBlizz said above;)
I am running an Asus Maximus VII Ranger Mobo which I know is 2x16x PCI-Express mobo so maybe I can't see a diff. In any case, try setting the original DOOM SLI (0x00000001) and see if it makes a difference. Really curious about it;)
SLI in OpenGL is always a hit & miss, unlike DX where you know it works;)) Sadly I only have my Surround RIG with SLI (and I am playing the game in Surround 5760x1080 with scaling of 70% = 4032x756 rendered resolution and I get 90-120FPS)
I gave a quick test on the new fix but I didn't spot any difference in performance...so I pushed it... maybe the old SLI flag is better?

yes, negative scaling is gone, no more framedrops with AFR2, but max fps i can get now in 2D mode is 100fps at 1080p, at higher res framerate is similar to single gpu, and bad flickering only at 1080p 2D mode, maybe this flickering issue is only on my end cuz i dont have 3D emiter hooked up to my pc anymore,i think this game needs more fixing for SLI to work properly but Helifax u are very close
i download this fix to check if SLI will work better in 2D mode than now, and there is progress

From what I read, id stated that SLI "caused" issues with the single player campaign. Because of this, it was disabled in 365.19 by Nvidia. 368.22 also does not have a Doom SLI profile from Nvidia because they are still working with id on the issue.
The multiplayer beta had SLI using 365.10 because it was working properly with it. Some people are still using that driver for that reason.

Strange (probably), but with new fix I see no difference at all. Still negative scaling. Also, rolling back to default SLI bits didn't change anything :) Probably single GPU is the only way for me...
P.S. I've checked my mobo specs, and yes, indeed - it supports dual PCI-e with 8x speed only... :/

With the latest version I actually get SLI scaling in Surround;) Now I can play at 5760x1080 (90% scaling) with 120FPS. Previous it was 5760x1080 (65-70% scaling).
I am unsure why it doesn't work correctly for you though... (Probably because the PCIE changes speed from 16x to 8x in SLI ?)

with the fix, plz set shadows to LOW, and report back, first place that will exibit negative scaling is in the begining of the game, when u are revived, and when u kill all the monster with your pistol, u will be able to put your green armor suit, and dont do that, just get very close, and just look straight at him, if with LOW shadows no fps drop then u will have no negative scaling through entire game, ive tested almost every level, no more negative scaling with shadows set to LOW with the fix, but i notice that now OpenGL is a bottleneck, cuz one thread sometimes is hiting 90%, overclocking my CPU to 4.8ghz didnt get me any single frame, and my sli setup was chilin at 135fps

Cool! Interesting find;)
I tried it and I could also see the FPS not flinching from 120 FPS to 100 what it normally does;)
Yes, there is some overhead. The wrapper adds some CPU overhead (0.8% measured on my i7 4790K @ 5.0Ghz)
The OpenGL-DX interoop layer that is part of the driver also adds around 8-10% as well.
If you are familiar with multi-threading programming, this is because it locks the textures, so only one thing is writing at the the time. As a result you get a CLEAN and nice image, but you lose some performance;) If you don;t lock and 2 things access the same resource you get strange results. Unfortunately there is nothing you can actually do about it;) I am sure the driver is also doing a lot more complicated stuff in the background, but I can't see;)
If you look at 3D Vision:
- let's say you get 100% performance when 3D Vision is disabled in NVPANEL
- If you enable 3D Vision in NVPANEL but play the game in 2D (CTRL+T to make it OFF), you will notice you lose around 15% of the "pure" 2D performance. This is because the driver is still stereorizing things in the background but only showing one buffer;)
I have optimized my code as best as I possibly could;) But besides my code, the wrapper uses:
- Nvidia Graphics Driver
- NVAPI DirectX to OpenGL inter-operability layer
- NVAPI for stereo (separation + convergence + eye_separation/monitor size)
- 3D Vision driver branch for DirectX 9 applications (in Window/Fullscreen mode)
- DirectX 9 as well for context creation.
If you just look at the sum of all the other software it relies on;)) you can pretty much realise that some other software/CPU overhead will exist;)
I am actually amazed that it worked on every game I tested on:)) and the performance is pretty great!
EDIT:
I didn't targeted this at you. It's just a more general explanations on how things work;)

Because the convergence is always loaded from the ini file. You need to specify the convergence value there:
Save it in-game.
Open Nvidia Inspector and copy it from the profile
Paste it in the ini file.
Re-start the game:) It will now load the new one from the ini file.

u have problems with SLI cuz u are probably runing SLI in 8x/8x PCIe mode, DOOM is very bandwidth hungry, for optimal and normal SLI scaling u need to run DOOM in 16x/16x PCIe Mode, max two-way SLI. otherwise lots of negative scalling due to shadows limiting pcie bandwitdh, thats why we need to wait, @TiagoSousa(idSoftware) said on twitter that SLI-support is coming, prolly they will optimise shadows for 8x/8x with Vulkan

@Seregin: Try this version and see if you get better results;)

i download this fix to check if SLI will work better in 2D mode than now, and there is progress
The multiplayer beta had SLI using 365.10 because it was working properly with it. Some people are still using that driver for that reason.
In the 368.22 feedback thread
P.S. I've checked my mobo specs, and yes, indeed - it supports dual PCI-e with 8x speed only... :/

With the latest version I actually get SLI scaling in Surround;) Now I can play at 5760x1080 (90% scaling) with 120FPS. Previous it was 5760x1080 (65-70% scaling).
I am unsure why it doesn't work correctly for you though... (Probably because the PCIE changes speed from 16x to 8x in SLI ?)

with the fix, plz set shadows to LOW, and report back, first place that will exibit negative scaling is in the begining of the game, when u are revived, and when u kill all the monster with your pistol, u will be able to put your green armor suit, and dont do that, just get very close, and just look straight at him, if with LOW shadows no fps drop then u will have no negative scaling through entire game, ive tested almost every level, no more negative scaling with shadows set to LOW with the fix, but i notice that now OpenGL is a bottleneck, cuz one thread sometimes is hiting 90%, overclocking my CPU to 4.8ghz didnt get me any single frame, and my sli setup was chilin at 135fps
Cool! Interesting find;)
I tried it and I could also see the FPS not flinching from 120 FPS to 100 what it normally does;)
Yes, there is some overhead. The wrapper adds some CPU overhead (0.8% measured on my i7 4790K @ 5.0Ghz)
The OpenGL-DX interoop layer that is part of the driver also adds around 8-10% as well.
If you are familiar with multi-threading programming, this is because it locks the textures, so only one thing is writing at the the time. As a result you get a CLEAN and nice image, but you lose some performance;) If you don;t lock and 2 things access the same resource you get strange results. Unfortunately there is nothing you can actually do about it;) I am sure the driver is also doing a lot more complicated stuff in the background, but I can't see;)
If you look at 3D Vision:
- let's say you get 100% performance when 3D Vision is disabled in NVPANEL
- If you enable 3D Vision in NVPANEL but play the game in 2D (CTRL+T to make it OFF), you will notice you lose around 15% of the "pure" 2D performance. This is because the driver is still stereorizing things in the background but only showing one buffer;)
I have optimized my code as best as I possibly could;) But besides my code, the wrapper uses:
- Nvidia Graphics Driver
- NVAPI DirectX to OpenGL inter-operability layer
- NVAPI for stereo (separation + convergence + eye_separation/monitor size)
- 3D Vision driver branch for DirectX 9 applications (in Window/Fullscreen mode)
- DirectX 9 as well for context creation.
If you just look at the sum of all the other software it relies on;)) you can pretty much realise that some other software/CPU overhead will exist;)
I am actually amazed that it worked on every game I tested on:)) and the performance is pretty great!
EDIT:
I didn't targeted this at you. It's just a more general explanations on how things work;)

BTW, any idea why when I save convergence with CTRL+F7 it resets right after that?
Thanks.

Because the convergence is always loaded from the ini file. You need to specify the convergence value there:
Save it in-game.
Open Nvidia Inspector and copy it from the profile
Paste it in the ini file.
Re-start the game:) It will now load the new one from the ini file.
