sorry for my english
i get strange stuttering issue with my pc:
core 2 quad q9400 2.6 ghz
amd 6950 1gb
4 gb ram ddr2

in some singleplayer levels of Mass effect 3 like the first mission on earth i get small occasional fps drops while looking around.
after few seconds they are gone and my framerate returns to normal 60 fps. It is almost like the game loads level around me. Rly annoying.
same thing with multiplayer maps in Bad Company 2 - game stutters for few seconds, than goes back to normal.
But for example BF3 and many others work fine.
is this normal? somebody else get this?
i even post a screenshot
