Since Patch Y I have been unable to play LFS due to stupidly low frame races more notibly in South City but also at other tracks too when there's more than 8 cars running (more than 3 cars on SO).
I've tried Patch X clean install and that runs fine 100+fps (down to 50fps with 10 AI cars). Then I move to a clean Patch Y install and all that drops to single digit FPS when there's more than 3 or 4 cars around online. As I understand it online uses up less of the system resources compared to running AI. Am I correct here?
With patch X i ran all graphics options menus set to the right side which as i understand it is high detail for LFS, in Y I ran with them all set to the left side with no performance increase at all compared to them all switched to the right side. I use 512x512 skins from LFSW, however I've also tried the 256x256 setting which made no difference.
I've also tried new graphics card drivers, old graphics card drivers (removing previous driver fully first), turned Hyper-Threading on/off.
Other games run fine on high details (RACE07 and rFactor), so it's not a hardware problem, it's a problem with Patch Y.
My specs are
P4 3.06GHz
2GB DDR400
GeForce 7600GS 256MB
