Hello. I have a 2600+ and a gig of ram id really like to keep. FarCry runs ok at max settings, however sometimes it just runs like an absolute dog. Notably inside with the flashlight turned on. With the flashlight off i get ~70 fps, with it on i get ~22 fps (this is everything as high as it will go). Im wondering if the lighting calculation and all for PS2.0 has any load on the CPU, and if a new vid card will remedy this. Thanks!

I'm guessing that the flashlight effect is produced via a projective texture, possibly using something similar to depth-buffer shadows. If that's the case, then multi-pass rendering is required, which may result in a performance hit. Either way, the CPU load for the effect should be minimal. Projective textures have full hardware support.

I *believe* the flashlight is mainly a GPU task, though your CPU ain't doin' you any favors in Far Cry, either. What video card are you using?
