I cannot believe I am saying this, but I just downloaded GP4 (of course only as a try before you buy
) and all I can say about the frame rate is urghhh. My system is:
2ghz Pentium 4
256mbDDR ram
Geforce 4 mx420
The frame rate was disgusting. On GP3 I was pleased with the 27fps or so I got, but 18fps??? It runs way too slow to enjoy it and to be able to drive properly. I put nearly everything down to low - and I got 20fps.
Hopefully the official release will somehow be different, all I can say is people with lower specs are in trouble.
