Q6600 @ 3Ghz
HD 7850 1GB
4GB DDR3
750W PSU
Win8 RTM
1680x1050
graphics maxed out obviously (vsync on).
OK so for no appearent reason when driving on the START/FINISH straight, GPU usage drops to lows 60s%, FPS drops from 60 to ~40.
CPU usage never seen higher than ~75% there, so no room for ANY bottleneck. This is so annoying that game becomes practically unplayable...
Tried lots of drivers, results were the same.
What could be the possible reason for this nonsense? I'am confused
btw, when FPS drop occurs CPU usage rises from 60s to 70s. Core parking disabled in windows.
PS. The highest GPU load seen in this game was about 80% (when getting 60FPS in other part of the track), so it is not 'usage wall'.
PPS. Temps no higher than 50C
