sorry, i know its not gp4 but some might be interested. ive just finished the download and installed on my xp partition, havent had a go with a wheel yet but game seemes to run very fast, ive only a 1gig, gf2 . it seems the games been designed for low spec, rather than great graphics, i ran it 1280x1024 32 bit high detail and was getting 60 fps, normally i dont bother running games under xp i load up 98 for that.
