My PC Specs:
Phenion II X4 955 3.20GHz
8GB DDR III
HD6870 1 Gb DDR V
My native resolution is 1920x1080
My CC is set to balanced - Triple buffer on - ATI AI off
In Game
Ground Geometric Details 35.00
Ground Texture 5.00
Model Geometric 35.00
Model Texture 8.00
If i lower more than that i dont fill any fps gain.
And if i put everything ON a just loose 5 fps.
But...
If i open a session alone or join a online session in a SX track i get 125 fps.
Until 9 bikes i still get the same 125fps, but everybike added after that adds a sensible weight on my PC performance, to reach a point when we have a full SX gate my game is completely locked , running slower than my still camera can shoot a surfer.
Any tips apart from upgrading my game rig would help

Thanks
