Fps in game keep changing every 15 sec. If you just start WoW fps will be around 50-70 and after 15 sec it will drop to 10, and after about 15-20 sec it will become 50-70 again etc. So basically fps keep changing all the time and doesnt matter in which location you are. Also there is no difference if you minimize video options.
I changed all drivers, i was trying different versions. Also I changed power supply unit, mother board, ram, and cpu cooler. Current cpu temp is about 55C and video card temp is 51C.
I tried to delete WTF folder and CASH folder. Also I tried to reinstall windows and WoW.
My current system is:
PENTIUM D 3Ghz
Dual Core Intel Pentium D830 Stepping:B0
3000.1 MHz (current clock speed: 3000.1 MHz)
4Gb DDR-2-SDRAM 400/800
ASUS 8600GTS 256Mb
Sound Blaster Audigy
current driver ForceWare 174.93
running windows xp sp2
Also I tried to run WoW in window mod and without sound.
Nothing really helped.
Could you please help me! I dont want to lag during raids!
