Tony Hawks American Wasteland

[Stonerofwar]

Ive looked a lot for information regarding this game and best settings to achieve good fps, I have fixed all the graphical errors etc, but I cant get my fps to get above 25 or so. It never hits 30 unless in a menu or loading screen, then i get 60-75. Ive seen people with similar specs achieve a strong 60 consistently so what am I doing wrong.

I doubt you'll get full speed with those specs. As far as I know all Tony Hawk games on PS2 have the same issue that once the camera turns towards the centre of a map, the fps drops. With my previous CPU, which was slightly stronger for PCSX2 than yours, and a better GPU, I struggled on the other Tony Hawk games, usually getting between 35-40 fps.
