E5500 2.8 GHZ Radeon 6850 HD 6 GB RAM not solid state Up until now, I've had 100% instances of CPU throttling, but have been able to play the game on High+ ("Ultra") Settings since launch, without it ever mentioning GPU. GPU fan was never noticably loud, either. Come patch, GPU throttling kept popping up, so I decided to turn down my settings. I've turned my settings to everything from Low to High (Ultra is defaulting to Low) with shadowquality=0. Results Shadows are always on FPS is identical to previous on patch in low-activity areas, but it's saying GPU instead of CPU throttle in certain circumstances FPS visibly stutters, but is numerically identical to previous patch in high-activity areas, GPU throttle when looking away from busy base, CPU throttle when looking at busy base. GPU is temping up to 90C while looking at the in warp gate, claiming GPU throttle (looking at the ground) Limiting FPS (to 30 or below, normal play is 20-25) only lowers GPU MAX temp by 5 degrees. FPS is identical between Low and High, no change in GPU activity, same throttle indicators Manually limiting the FPS to below the GPU limited threshold does not prevent GPU heating There is no reason a 6850 should hit 90 degrees with everything on low, in sanctuary, at 3 AM EST.
