Mouse Lag

[djc23]

Try using a program called MultiRes to lock your monitor to a certain refresh rate. This application is free, and is quite useful. I can't provide too much evidence as to why this might work, but its worth a shot anyways. I assure you that there is no malware in the program. After all, driver packages such as Omega's ATI drivers actually come with this application.

Sorry it didn't work.
