After i've played BF3 for abit in Windows 8 - it starts to stutter as hell. Apparently it goes from using 3-4gb up to 8gb.
This is a well known bug for using amd cards combined with win8 and bf3. Not everyone has it though.
Anyway, after reading around on the net I still can't find anyway of getting rid of this anoying memory leak or how to clear my memory without rebooting. When you check the taskmamanger you can't see anything using particulary much memory 
shitloads of new stuff in my pc. Cant keep track of it all.
