why gta iv is working so freaking SLOW (on new rig)

Voath · 10-26-2011, 08:12 AM

Month ago i bought new computer. I thought it'll be awesome for new games also for gta iv, because i had low fps with last comp.
My new one is radeon 6850 asus + athlon x4 645 @3.1 + 4gb ddr2 kingston. And gta iv fps is like on old computer... i said what the heck and tried to find fix. I clocked cpu, card and no effect on fps, tired some fixes with win 7 like running like win xp and no effect.

my old rig: radeon 4850 + athlon x2 5000+ and 2gb ram ddr2

Almost same fps - 2 different rigs - same resolution 1280 x 1024 - low -mid- high it doesn't matter i getting 7 - 17 - 25 (all time) - 35(max when looking to warehouse) fps at day and >20-29 (max 35) fps at night
latest radeon drivers

I noticed also have some problems with other games like brink, newest stalker, vindictus

i hope you can help me...

EDIT: my psu is ocz stealthxstream 500w
and motherboard: asrock n68s-ucc

and gta iv benchmarks say i getting 44ffps fraps in-game showing no more than 20-30

What I noticed with my HD5770...
Catalyst AI should be disabled and "flip queue size" set to 3 or more (vsync is off). This way i can get ~58fps in benchmark but number drops some ~15fps if I try with any other AI/queue setting in Ati Tray Tools. I assume they go by same name in Catalyst Control Center.
