SLI Performance has degraded with the new driver. GPU utilization rates have dropped from 90-98 percent on all gpus to 40-70% from driver 326.01 The attached charts show performance at Brianza with Build 240 @ 8002 x1440 resolution at Level 8 with HDR, no HDR and low level reflections witrh no HDR. No HDR gives a steady 60 fps. Low level reflections halve the fps from 60 to about 34. HDR no reflections drops framerates to 14 fps.

I tried these drivers on my gtx780 single card, I lasted about 20 minutes till I deleted and reinstalled the older ones. Its funny because they are meant to increase framerates for the new gen however all I got was terrible performance, I never got a driver this bad from nvidia for rfactor 2 its normally a performance increase.
It seems that HDR and road reflections are the main causes for framerate losses. The attached graph shows 4xMSAA + 4xSGSSAA with low car reflections but no road reflections and no HDR. This setting eliminates aliasing artifacts of lines on buildings and road surfaces. A solid 60 fps is possible with multiview, but the 326.41 driver does introduce more stuttering on all tracks that the previous version. View attachment 9093
None of these drivers have ever been optimized for rFactor2 or any other sim i know besides console ports. I don't think they ever will, Nvida and ATi have a million games more popular to worry about.
Hi, Ok, which is in the best driver at this Time? I have 2 x GTX 680 and I7 4,5 Ghz CPU, and the Performance is "terrible", with the Nvidia 326.41. Which nvidia driver have the best rF2 Performance now? Thx
