Problem: Very bad performance in Wrath. FPS barely goes over 30-34 in Dalaran.

No matter what I enable or disable, such as vsny, tri buffering, 8x, 4x, 2x, MSAA, full screen or windowed, its sits at 30fps. >.<

I just noticed that in GPUz, cards 1 2 and 3 have 0% load, and card 0 is running at 60% load, and clocks of 500/500 instead of 500/900

Computer in question:

Core i7 920 stock, 2.66
12GB DDR3 1333
150GB 10k rpm raptor for wow and OS
2x 4870X2 2gb, crossfire enabled
Windows server 2008 with all updates
Catalyst 8.11 x64

Tried so far:

Disable CrossfireX, Performance does not improve or worsen.
Fiddle with processaffinitymask, CPU does not seem to be a factor, fps remains the same
Delete everything but data and redo WTF settings from blank file, same
Format and sinatll WIndows 7, about 10 fps increase, nothing major
Format and install WIndows Vista Ultimate, 4 fps drop. o.O
Format and install Server 2008, still sits at 35 fps.

Have not tried XP yet, I can't find the discs and I can't be bothered to redownload from MSDN atm.

I noticed that the fps will randomly spike up to 230-300 for a couple minutes, and everything is perfectly smooth, then it will drop and chug at 30 again. NO clue why, temps sit at 87-95 and hover there. Seems to be nominal for the cards. Processor usage sits at 100% for core 4 and 50% for core 5.

I don't understand computers. My other computer gets 60 fps locked with vsync on and 4x MSAA.

help


I want to throw this thing back at Frys and buy a Mac... at least they work

Yes, all drivers are updated, I have no viruses, my PSU is a Corsair 620watt with 50amps on the 12v. Enough for the cards, please don't tell me to buy a new PSU like everyone else does, wattage is not everything, and this computer tested perfectly fine on a 15 hour vantage loop on extreme.

And dows keyclone handle cpu affinity ok on an i7? I cannot set it in the program at all
