sorry if this is a repost, but I could not find any answers to my problem other than mouser driver
I am running Windows 7 x64 on my laptop.
The hardware is; i5 M460 processor, ati hd5650 gpu and 8gigs of ram. also 7200-rpm hdd.
While I am doing some "heavy" work on my laptop such as opening a raw image (NEF) file (in PS CS5 or Faststone), or applying sharpening or noise reduction (in PS CS5), or starting iTunes, my mouse lags like I am playing a video game at 10 fps. cursor moves and clicks are all delayed. when such process is complete my mouse goes back to normal. Generally it seems like when the system is "strained" the mouse lags.
I did not experience such problem until recently. For some reasons I had to format/reinstall my Windows (the same Windows) several times, but mouse lags are still there. No issues in CPU or GPU performance (at least not that I am aware of), but these lags has gotten sort of annoying.
I have been experiencing this problem with different mouses.
Can you please help me how to solve this?
