weird: game rendering very choppy only in fullscreen

Posts: 9
hey guys!

i just had a 2 week pause from starcraft2 and wanted to play again, but i got this weird issue:

when i run starcraft2 in fullscreen or windowed(fullscreen) mode on ultra graphics settings, it is suddenly choppy as hell (i get about 2 to 1 fps). when i switch to windowed mode and maximize the window, so the application has to render nearly as much pixels as in fullscreen, it suddenly is fluid as it was before my break. when i set the graphics to low, its fluid in fullscreen mode again, but why should i stick to low graphics with my fairly high power machine?

before, i was able to play on ultra in fullscreen with no problems. my specs are:
ATI Radeon HD 5800 Series
AMD Phenom(tm) II X4 940 Processor
resolution: 2x 1680x1050 (native and fullscreen)
graphics drivers (catalyst) are up to date

while playing around with the different graphics options, i found, that only the shader option seems to affect this issue. if its on low and all other settings on maximum, tha game runs smoothly. if its medium, framerate drops to about 10fps. on high i have only 2fps.

again, i CAN play sc2 on all ultra settings in windowed mode (maximized the window to 1680x1050) with 50+ fps, but the windowed mode does not let me scroll the way i am used to.

please help^^
