I get a high CPU usage scrolling on websites, up to over 50%. Especially this forum scrolls very slowly / jerky. This happens both in IE and firefox. I see some event 500 (Graphics subsystem resources are over-utilized) and 501 (Graphics subsystem resources are over-utilized) in the performance log, so I suspect the culprit to be the ATI board. I am using the latest drivers. The system is a laptop 2.8ghz 4 gb ati mobility radeon 3650. I see the same problem on a Dell laptop with a ATI HD 3200 getting a CPU usage over 70% scrolling on windows7forums.com. Any ideas?
