I logged on and about 5 min later got huge fps drop, the whole game slowed down to about 5 fps.
I have tried:
Trilinearfiltering to "1"
All low resolution and settings
Machineclass to "1"
Deleting D3Prefs.txt all together
Updating mac, graphics card ect.
Resetting PRAM and SMC
Deleting Adobe Flash/ reinstalling
Cleaned the dust out
Tried deleting all unneeded patch/report errors
Set ChannelsToUse to "16"
Whenever I restart my computer it fixes it for about 5 min then the FPS drops again, I know im running a mac but it has been running it for over two month just great.
Any suggestions would be very welcome thanks.
