SLI working

[Mr Greezy]

HeavyHemi...

Are your SLI framerates good in fullscreen or are they windowed like Grathos?

Also, is your setup just the new driver + .inf file + AFR 1? Or are you doing, as Grathos said, this: SLI compatibility bits (DX10): 0x000000F5?

Thanks for finding the driver stuff. I'm hoping it helps with my GTX 470s.

Man, I'm still very hesitant to buy this game. I've got 3x 3GB GTX580's in Tri-SLi and 3x displays @ 5960x1200. I don't want to have to drop back to using two cards (through drivers or by removing my third card) just to experience this game. Even then, I'm still not sure that the Aspect Ratio will be sufficient to take care of the stretching that the original IL-2 had.

I'm running full screen 1920x1080 all in game settings maxed I'm averaging 55-60 FPS in most areas with 80-905 utilization on both GPU's. Where I drop into the 20's is in urban area with a lot of buildings. My current setup is the new driver using the inf file (it's required) and AFR 1. I am not using the SLI compat bits. All the modified inf file does is add hardware information for other Nvidia cards so the driver will install. Reinstalling a standard GeForce driver will not be affected.

Oh man, you should be banned for posting things like that...

Unlike IL2FB the 3Renders option is not working (yet) in CoD so it is a problem.
The only solution I found was to run the game in Window mode as my pictures show.
So, the 3Renders option is the key and we have to wait for this to happen before we can enjoy nice wide view.


In the meantime, the power of one 580GTX 3Gb will be enough to enjoy the game in full graphics so if I were you, I would not hesitate a moment buying the game and enjoying the graphics detail on single GPU mode. Afterwards with some searching, you will be able to activate the second GPU as well and this will be more than enough.

By the time the 3Renders option will be available I am sure that SLI ill be working without any shortcuts and this will be the time where three GPUs will show their value.

nice rig, by the way!!!

Great post..very helpful

Any ideas why I cant find this setting using 275.33 + 1.9.55:

SLI compatibility bits (DX10)

I dont see it...

EDIT: Nevermind I found it: I was missing CustomSettingNames_en-En.xml. Needed to be next to the .exe!

= didnt work this attempt..hmmm

Ill have to try again

BTW: shadows off is blasphemy!

Ok, I've got it going too with 2 460 GTXs, thanks to this post 335th_GRAthos. I can see an improvement in FPS. However, I think Im getting some micro-stutter at times??? (could be Im crazy)....I'll have to do some more testing/tweaking when I get some more time.

Heres what I did so far in order:

(1) updated to 280.19 nvidia driver
(2) I swapped out the nv_disp.inf file with the one linked
(3) Used Invidia Inspector to change
(a) SLI compatibility bits (DX10): 0x000000F5
(b) NVIDIA predefined SLI mode on DirectX 10: SLI_PREREFINED_MODE_DX10_FORCE_AFR

I hope changing the nv_disp.inf was correct. Wasn't sure if that was necessary with this beta driver also. Please let me know if you see anything wrong or if I can tweak something. I'll repost if I have any better results

Thanks again for getting this working for me

Once you've installed the driver, changing the nv_disp.inf file doesn't do anything. It's only referenced during the driver install. As the 280.19 driver is a unified GeForce driver, your card is supported. However, nv_dips.inf files are specific to driver version. So if you try to reinstall the driver from the C:\nvidia folder by running the setup.exe it will likely fail because the driver version in the nv_disp.inf file header is wrong. You can read the .inf files with notepad.

Thanks for explanation....I have another question.

Does this fix "force AFR" work if SLI is disabled in the NVIDIA control panel? I just noticed my box was checked for Disable SLI. When I changed it to "Maximize 3D Performance", the game breaks with flickering and all sorts of craziness with 15fps. I must have done something wrong?

I have to keep disabled SLI in this setting. Is this correct? or do I in fact not have SLI going? Looks like I dont...hmm

Hmmm...
As far as I know, Disable SLI at the control panel means that you do NOT have SLI.

It is also easy to cross check whether your two cards are working. Look at my screenshots at the far right you can see I have the monitors for each of the GPU cards and they show different temperature and MHz frequency for each card with SLI working and not.

Yes, I monitored it with afterburner and was showing only one card. I'm not sure how that was disabled, but it was. The good news is I was getting playable framerates with one card, but I don't have SLI working=

Very dramatic glitches and fps loss with SLI enabled...back to the drawing board I guess. Thanks for the help. Let me know if you have any ideas.


This config did not work for me with or without the epilepsy filter.
