Luthier-Will SLI be fixed in the patch?

the game itself is not written in C++ but in .NET Interop is what happens when you go from managed to unmanaged code (speed tree's ,direct X...etc) which causes a performance hit.

here is a much more in depth explanation

Thanks.

From what I read the stutters are from badly/hastily coded software.
Not hardware issues. Correct?

sloppy coding just exacerbates the problem...but the interop is still there even with clean code and if you read the latest update Luther said "reduced" and "decreased" not fixed! as I understand it this is just the nature of the beast....interop makes a performance hit whether it be minor or major.

A robust rig will show less of the issue but it will still be there

I have tried disabling one of my cards and that shows zero use on the V/mem on that, and the fps drops to about 60% of what I get with both cards working but the V/mem still shows near max use on the working card. I have my clocks and voltages set to the same for each card even though they are from different stables and the percentage of use on each card only varies about 2% from one card to the other, that also varies with one card using more, then the other. Temps on both cards are within about 2--3deg of each other with card 2 always slightly lower than card 1 (this is what information I get from the different makers, the EVGA slightly hotter running than the Asus) and both are within the 50--60deg range. I wonder if others using Sli are getting the same results, it would be interesting to find out.

Here are my GPUs full bore in CLoD

It was the same with 1946. The stutters ended once a rig had a processor fast enough to compensate. It's just going to be a long road to perfection, but I'm happy to shoot you all down with the odd stutter till then

Using sli doubles the fps (130fps) but there is a very annoying "unsmooth" flow of the screen, mainly due to lack of power of the GPUs and lack of V/mem.
I have experienced exactly the same result trying CoD on a PC with an NV420 GPU.

So, non-sli is less fps but smoother game. Also the moment V/mem will reach 99% capacity, the fps will drop by half.


Temps on both cards are within about 2--3deg of each other but it depends on which card-fan has better air intake, both GAINWARD are at the 75deg range with optimised cooling, 83deg without optimized cooling.

I'm confused. If its because my processor is too slow, why are none of the cores maxed out ever? I never go above 60% on any core.
