When I try to record a screen capture video using CamStudio (portable version), my mouse lags so much that it is practically impossible to do anything. Reducing the size of the region I'm capturing makes it run more smoothly, but still lags very badly every few seconds--enough to be unusable.
This problem occurs exactly the same on Windows 7 and XP
I have no problem whatsoever when I use Microsoft Expression for screen capture, even if I capture the whole screen (but I need it to be portable and to work on multiple OS's)
The only suggestion I was able to find through googling was to turn off Hardware Acceleration. They said to go to Display->Screen Resolution->advanced settings->Troubleshoot->Change Settings to do this, but when I get there, the "Change Settings" button is grayed out.
What should I try next?
