ok there is a cache setting here it is probably set at 32 mb!set this at 248 mb max if you can!make sure it doesnt exeed your network cache!mine i can set it to 512 mb!

i am mentioning this cause it is very tempting to go to high !why i chose 248?because it is around the lower limit  of the paging file.if i recall it is 250 .if you set paging file to 0 it auto to 400 mb !try to stay lower then the paging file minimum since the real minum is around 250 by setting cache at 248 mb max you should be safe.(personally i would go half of that around 128!)

WinDrv.WindowsClient  do not set this lower then 24 (fps)yes eye candy are nice but 24 is the minimum!i recommend 29.9
