Hey guys. I recently bought a new computer (parts then built it myself). For some reason though, some of my older games lag considerably when I ramp up the graphics. My computer runs Prince of Persia (latest one) on full graphics perfectly but struggles with Psychonauts, Warcraft III, Frozen Throne and Dawn of War (only when using the Daemonhunters mod). I am also experiencing severe graphical glitches in both Fallout and Fallout 2. The screen is filled with all colours of the rainbow, with only faint outlines of shapes visible. It’s pretty much fine in game but cutscenes and most menus are messed up. Here are my specs:
Gigabyte GA-P55-UD3R Motherboard
Western Digital Caviar Black 500GB
Intel Core i5 750
Patriot PC3-12800 2x2GB DDR3
Sapphire Radeon HD5770 1GB
Microsoft Windows 7 Home Premium 64bit OEM
Corsair HX-650 Power Supply
Thanks in advance for your help!
