Yes, the truth...people here have to be free to say the truth, this is the message of this thread.
All the people here have to say the truth, so I beg moderators, for the second time, to put this sticky thread up on the list.

Correct, Luthier has consistantly mislead everyone regarding SLI, even during development.

i can now say after some testing that my Xfire isnt working , usually around 5% on the 2nd GPU , saw a max or 17%

My xfire is working 2x4890's, both cards report same usage through gpu-z, and the usage scales with higher gfx options, I did have problems at first, I found an uninstall, then a CLEAN reinstall of drivers (currently 11.8 ) is what works, then don't touch anything driver side except vsync, start playing with it and it leaves out optimisations that in my experience with buggy ATI drivers never get put back again

i just tried with two runs of GPUz running and did indeed notice full load on both cards , couldnt get the log for both cards though . tbh when i was testing i was in windowed mode so maybe only one card works then ..

but anyhow wasnt getting these fps yesterday , for me starting the game from the launcher in the game folder ( or shortcut ) is better than using the launcher the game installs on the desktop

( steam://rungameid ) etc

I don't need it because i always run single GPU setups: much easier to buy a good single GPU card and upgrade it once every two years, than spending money on dual GPU setups and having to wait for optimizations and profiles every time.
I don't usually play blockbuster titles that get immediate attention in this regard so i never go dual GPU, it's like spending money on performance that isn't always realized.


I have no objection to it being added to the game of course, since other people use dual setups and would need such a thing. The question here is on what priority?

Even a poll wouldn't be representative since a lot of people don't frequent this forum. I don't know if there's a way to do a hardware survey via Steam that is limited only to CoD owners, that would be the best criteria available: it would really give us an accurate indication of how many people run dual GPU setups and of which company, so the devs can decide on how to prioritize it.

Majority of people with dual GPU setups in the survey? Then give it some priority and even further, prioritize first the kind of setup that most people have (SLI or Xfire).
Majority of people in the survey running single GPU setups? Then give priority to other bugs.

That would be a fair and accurate solution i think.

I only have a single gpu, but those running sli or crossfire do deserve to have it running properly. At what priority is the question. General optimization and other things/bugs seem to be more pressing.

Still voted yes for above reason. But I do agree with blackdog, a good single gpu solution is imho the better way to go, there is an link to an article about measuring fps, single gpus and multiple gpus on this forum, very interesting and demystifiing and to me confirming that multiple card solutions maybe be a bit overrated. It is in the performance subforum, "nice article on gpu testing".

Rick, did you get anything else running/improved via nvidia inspector. The profile is, just like in the nvidia cp, "launcher.exe", right?
I couldn't really get any more improvements than I already had with the normal nvidia cp, such as force vsync on.

Good idea, if someone could do it would be great.
At the moment we have to be satisfied to see the trend inside this forum.
A sticky thread maybe could help the poll...

Could you plz share your knowledge with us?

I have tried to follow some posts that claimed to have SLI working.

I get both GPU´s to work at the same load, but i get no performance gain and my FPS get more ups and downs (my FPS are lower but more stable with single GPU config).

So, can you help me???

I need one. My 4 year old system has 2x8800gts and in Il2 it gives a 100% increase in fps. Every bit of performance I can squeeze out is welcome untill I get a new system this winter.
