I recently bought a new rig:
Intel Core i5-3550P @ 3.1 GHz
HIS AMD Radeon 7790 1GB
I tried playing GTA IV but it doesn't matter if I play max out on 1080p or all details on low on 1080p - the game lags every 4 seconds for a good second like the framerate drops. It also doesn't matter if there's a lot action going on or not.
I tried an unmodded version of GTA IV with Patch 126.96.36.199. Should I try 188.8.131.52?
Drivers are all up to date and I'm on Win 8 Pro 64-bit.
Thanks in advance.
