Firstly I know that WoW has a max FPS of 60. However I just got both my Sister and her BF a ATi Radeon HD 4850 1Gb Video card, but I am currently not happy with the frame per second they are getting. Currently they are getting about 20 FPS on Yogg-saron (heroric). Any way in which we can improve this?
System specs are
AMD Athlon x64 Dual Core 5600+
2Gb DDR II Ram
Gigabyte Motherboard
ATi Radeon HD 4850 1Gb Video card
Windows Xp Pro Sp3 (SP2 in the case of Her Bf)
Any suggestions?
