Verwandlung: Very depressing performance here:
System:
Gigabyte P55 motherboard
i7 920
6gb ddr3
hd 4890 (updated drivers etc)
Vista 64
Game feels unresponsive and laggy.
ASvinda: Try these tips
1. Run the game in windowed mode.
2. Enable Vssync and force it on with RadeonPro
3. Disable anti aliasing (also in radeon pro)
4. Max the Flip Size queue in Radeon Pro
5. Enable all optimizations available in Radeon pro
6. Fake the game to think my Graphics card is an Nvidia 465 GTX using RadeonPro (google the vendor ID).
