Hello

Ok i have been puzzling this issue for a month or so now

I have in the past managed to use Furmark to stress all 4 GPU's of my Dual GTX 295 Quad SLI set-up but recently whenever i try and use Multi-GPU Furmark it will only stress 1 GPU, this happened when both GTX 295's were installed and the same is happening with just 1 installed.

I ahve removed and reinstalled drivers, i have tried new drivers, i have not tried older ones yet, this issue arose when usin 195.xx or later, i am now on 197.13 and its still happening.

On a side note Furmark seems to appear as "Quake Wars" in Nvidia Control Panel and is set to use

Anyone had this issue or know of a fix please? Its set to Force alternate frame rendering 1 when using SLI, cant remember what it had for Quad SLI but it was still named Quake Wars in the profile section.

    Try uninstalling Furmark
    Then reinstall it to see if that works

    Yay for me.
     
    Does anyone know why this happens? Does one card get dedicated to "Post FX"?

    I would be interested also and it would be good if i could have it enabled but i am sure the GPU's get a good enough stressing anyway without it, aslong as all GPU's are under load thats the main thing.
