GPU overload...
????
Some Video cards use system memory and that is a lot of Graphics processing taken together with any applications you run, along with CursorXP and Windowblinds for Theme continuity.
just guessing...
I know my desktop doesn't care what I throw at it, nothing seems to slow it down much.
But this laptop
900mhz, 512 meg Ram with a few gig's of free space, absolutly crawls...... with OB,DTX,WFX,CXP and WB loaded...
WB, CXP runs fine
WB,CXP + WFX crawls after about 10 minutes
DTX, WB, CXP, OB crawls from the start
DTX,WB,CXP - crawls after about an hour
DTX,OB,WFX - crawls from the start
The most common I found in all instances was WFX always hits my laptop hard...
It's the chipset....
