Setting up Sli

Hi Diablo,

You could try but I don't think so. Inspector is for Nvidia cards, don't know if ATI have a similar program. If they do all I can suggest is try.

Cheers

Hi GRATHos,

The Vram issue is what I thought as well, so I have a poll running in the main section. Interesting to see the results so far, some with an excess of 1gb Vram are also having problems. About 75% of replies to the poll are having stutter problems regardless of Vram size. It is all pointing to graphics engine optimisation.

Cheers

Rick

Rick,

if you ever have some free time, test how SLI works in window mode....

I just noticed that my game runs very nicely at 3072x1024 window (my desktop is 3840x1024) but very poorly (with sutters) in Full screen or pseudo screen mode.

Who knows....

Hi GRATHos,

Tried your suggestion, made things worse as far as stutters were concerned. What I have tried is to use the best refresh rate my monitor will give, that seems to have helped a little (75hz).

Cheers

Rick

Hi guys, I'm using 285.62 WHQL 64-bit with two GTX480s. Your suggested profile results in everything being mirrored between the two cards in Precision (GPU memory, temp, usage but only at abut 50%) but no increase in frame rates and stuttering which I don't usually get.

Also, IL-2 doesn't appear in the Inspector list now. Do you know if there have been some changes in 285.62 that stop your profile increasing FPS or am I doing something wrong? Thanks.

Just tried Rick's settings and didn't work for me first time, only one GPU was doing the job.

I found out I had to enable another two options further down the list in nVidia inspector, and now SLI is working for me, both cards at 99%, temp at 80-81º and 50 fps average at 1680x1050 and medium settings ingame, very good

It doesn't show up actually. You have to manually create your own "launcher.exe" profile and check if SLI is really working using a tool such e-vga precision.

Are you absolutely sure your SLI is working?. Did you check it using some kind of tool like I was mentioning before?

Hi Guys,

Sorry I haven't been too active on the forum lately. The other things to look at is make sure that you don't shut down Inspector when playing COD, (you will have to select the correct profile each time as in my case it reverts to GLOBAL) just minimise it. EVGA Precision tool is a great way of checking that your Sli is operating as it will show: -

Temp of both cards
How the card useage is on both in % (I find that the demand on both cards shifts from one to the other thou not greatly as the graphics demand).
And FPS on both cards.
This tool is available through the EVGA web site and is suitable for all Nvidia cards regardless of manufacturer.

In the Nvidia control panel set Physics option to CPU (this takes the demand off the GPU).

I still have some minor stutter problems but only when down low and mainly over land (hope the coming patches will address a fully working Sli (this was broken prior to release and hasn't been fixed as yet, the profile I am using is a work around until then).

Cheers
Rick
