ok im DL right now, but this is exactly whats going on.. im playing planetside 2 right now and it was only showing 800-900mb being used but this is a beta game and still is being optimized but that doesnt explain why it showed 900mb still when in certain situations while playing it would bump up to 70-75% on the GPU.
Now when i ran BF3 it was showing the same thing.... so i looked around and was told to use driver sweeper to reinstall drivers etc... well i did and right after i i cleaned out of everything and installed the newest drivers... went on to play the same games.... the memory usage dropped almost by HALF! ?? and now i get reading 400-600mb on planetside 2 and 700-maybe 800mb tops on bf3.
