Hmm, ok. So turning off flick gestures seems to have helped a little bit. I have tried uninstalling the Wacom drivers and installing the default HP drivers (the OS doesn't want to give me a driver by default; the tablet just doesn't work if I simply uninstall the Wacom drivers) but the performance is the same. I'm hesitant to do another reinstall, but I will try that when I have the time. wisptis.exe priority is already set at "realtime", so I don't think that's an issue. I noticed that the effects of the lag seems to be of varying severity across different programs. In OpenCanvas 1.1 it's absolutely appalling (like I said, extremely hard to do rapid or precise strokes), but it's almost unnoticeable in OC 4.03. Why is this? Is this actually a driver problem or something to do with the apps themselves?
