Bad performance with 670 SLI
Closed, ResolvedPublic

Description

My cards often drop to 10 % usage.

This happen everytime on the helicopter showcase.

I get around 20 FPS and GPU usage on both cards are around 10-15%.

Disabling SLI fixes this and i get way better results.

i can sort of confirm this
with standard gtx670 in 2way sli
average gpu usage is 40% with it dropping much lower frequently
(measured by gpu-z)
disabling sli puts the single gpu at 70% average usage
both tests achived about 20 fps when looking inland on the helicopter showcase
