Hd 6770 problem

[blackbox009]

I have HD6770 with core2duo 2.9GHz and 1600x900 res monitor
I recently installed crysis2 and GTA4
crysis 2 is fine in hardcoremode.
But in gta4 it fails to get more than 17fps
//Also images are not so good at its good settings.
// I changed catalysts properties to its best but a narrow change in GTA4's output.
Why?

Upgrade you CPU to quad core so that you can play GTA 4 FINE and upgrade your RAM to 4gb

If you play GTA 4 set it to medium

RAM is 4GB

By default Crysis2 is DX9; so if you haven't applied DX11 patches then thats the reason why you can play it in hardcore settings as new cards are very good in DX9 mode.

For GTA4 try it in medium settings (your CPU seems to be a bottle-neck here at-least at your current resolution)

GTA4 wants Quad core and a fast one at that to be played at its best. Even a fast clocked Duo wont touch a cheap quad when it comes to that game.

thx 4 the reply guyz.... I dont think so that gta iv will give AA within quad core cpu or the latest one ... Cuz its the problem of vga which is not giving soft image AA ...

Ah i see sorry didn't quite get what the issue was just thought it was slow. GTA 4 needs to have the AA forced through the drivers from what i know of it. I don't have the game so am just reporting what i have read elsewhere. There are people reporting this issue and others are linking patches etc but to be safe i would stick to any patches supplied by teh games official site.
