anyone with more than 1 ati/amd gpu might have noticed that UDK isnt gaining fps with CF enabled

make a copy of UDK.exe in your bin32 folder and rename it to AliceMadnessReturns.exe

it wont be absolute 2x scaling all the time, but it helps

you should have the latest CAPs installed & let's say at least 11.2 drivers (i needed their dx9 dll to fix the sparkling spots)
