Dear oh dear, what is this country coming to, an aussie admitting he's a moron
Do a search on f1graphics, there's been a few posts on it and it's likely that there's some tweaked versions available for download. Also there is an f1graphics editor available for download, probably on this site somewhere
When you do get it up and running at a decent rate post your f1graphics file, I'd like to see it. Getting gp4 to run at 28fps with 80-120PO with a P3-500mhz is an achievement itself. Have you tried running without using the file? I've sent you mine to test. Good luck.
