SLI working

[335th_GRAthos]

Hi katdogfizzow, sorry for the late reply, I am somewhere at the Greek islands kitesurfing (yes, there is life besides CoD, actually, THANKS TO LUTHIER's fridays' posts ) so internet connection is limited.

Your SLI is not working.
The numbers you need to monitor in order of appearance are:
GPU1 core clock vs GPU2 core clock
GPU1 shader clock vs GPU2 shader clock

You can see that your GPU1 core and shader clock is working at full speed MHz as it should for 3D games. On the other side your GPU2 core and shader is idlling at the lowest MHz speed (in order to save energy).
Only this shows that your GPU2 is not activated.

This is step #1 to know that something is not working as it is supposed to be.

Only AFTER you have GPU1 and GPU2 working at full speed, then you need to check
GPU1 usage vs GPU2 usage
BOTH GPUs should be working in the area of 75%-95% in order to have the SLI system working.

I do not know why you experience so many problems, I am sorry for this.

PS. run the game in window mode when you do your tests, just to make sure you imitate the same testing conditions as I did in my rig.

Its simply not working for me. Tried every conceivable configuration. Thanks for the feedback...That kite surfing sounds awesome. Saw some of that recently in Key West. Looks fun as hell

A: At some point in the very hectic pre-release rush, we have broken SLI support and we have not yet been able to discover the reason for it. We are working very hard to re-enable it. In the meantime, disabling SLI will significantly boost your FPS.
