Gentlemen.....i guess old Geoff's got loads of Nvidia and Radeon shares cos everyone upgraded their pc to play GP4 it seems....
I heard that XP needs at least 256Mb ram so if that's what you got maybe it's a bit short or ram. Update all your drivers. Start with reso 800*600*16 with everything turned low and switch on what you like to have most (e.g. mirrors are nice but take a huge p.o.) 32 bit is out of the question. to let the game run smoothly it needs at least 20 fps i reckon. Better play smooth on a low reso than have stuttering gameplay on a higher reso.
I have a P4, 1,4 Ghz. 640 MB ram and XP with a GF2 Mx 200/100 and i get no more than 800*600*16 with 21 fps, videowalls and heat haze turned off and no dynamic environment mapping (po killer!). But it runs pretty good when racing. Try different graphics.cfg files some decrease po dramatically. But in the end it's what you are satisfied with is that determines whether your pc suck or not. Probably not if you are playing Solitaire. But probably if you want to run GP4 at full detail. Good luck!
