Hi guys, I have installed gta4 on my m/c that is having intel C2Q8200 cpu+2gb ddr2 ram+evga 8600gt(1024ddr2). The os is xp sp2, i've got rmn 40 error, and with a registry patch i'm able to play the game, but the fact is inspite of metting recommended requirements for the game, even on 800x600 resolution with everything lowest, i am getting fps no more than 15 on avg. Is it due to the fact the xp sp3 can resolve the problem, or anything else. the new thing is that i got a samsung 2233sw 22in monitor, but the resolution i have set is 800x600 only. Even crysis warhead is performing well with 4x antialiasing on the same system. Should i get the sp3 upgrade, or my m/c can give this much only. Please comment on this.
