I wonder if anyone else has noticed this problem, I noticed it mainly from IE and outlook both having jerky scrolling on html, in IE its not as bad but is noticeable on some pages. Also a 3rd party chat app I use called mirc which used to struggle a little in XP but struggles a LOT in windows 7 scrolling extremely slow aturating all processing power.
So I downloaded an app called passmark which has a 2d benchmark feature, downloaded some benchmarks from same hardware (but not all same cpu clock speeds) and then compared the results, on the right pic I underlined the other machines in the same colours as the graph.
any thought I be interested,
Now I have my theories as to why its so bad. It could be just very bad drivers, poor 2d coding (although this would be a surprise since the desktop is accelerated with aero), but I wonder if its to do with 'shared video memory'.
Shared video memory is something normally associated with crappy onboard gfx controllers. According to my display control panel my gfx card 8800gt has the following memory.
available graphics memory 3327meg
dedicated video memory 512meg
system video memory 0meg
shared system memory 2815meg
at a guess 'system video memory' is probably what low end video cards have, 'shared system memory' is something I never encountered before and is using ram as graphics memory?
gpu-z tells me something else useful and that is none of my onboard gfx memory is been utilised, which may indicate my aero graphics is using ram emulated as gfx memory which 'could' explain the slow performance, all a theory from me at the moment.
