It could be your driver (heh). Your 82865G card driver might have been updated by Auto Updates. mine was and 1 of my old games stopped working completely so i have to roll back to play it now. check Intel's site for the latest drivers, i updated mine and got a few fps out of it.

I have the same intel integrated graphics and struggle to get more than 20-30fps in a race but i find this is playable. If u have an agp slot (i dont) then get an agp card.

in the meantime, turn off every LFS graphics option, sky etc, LODs to minimum, texture filtering NONE and all mip bias to 0.00. textures & skins on low res/compressed. set ur screen to 16bit 60hz, z-buffer to 24, simple track off, v-sync on, limit fps to 58, min sleep 1ms, dynamic Lod red to 1 (max). All these things have helped me squeeze a few fps out of my ill-equipped dell.
