what the hell kind of donut computer are you running
A good old XP Professional.
You make XP sound bad, which it isn't. At all. Rather, we are interested in the usual specs like CPU, RAM, GPU, etc.
There is no program that will record something flawlessly. The only way you can improve performance is with a faster computer. Now, I'm not saying FRAPS is as good as you're going to get, but don't be saddened if that's the case.
(I've used both Camtasia and ZD Recorder in the past for Touhou, both of which underperformed versus FRAPS. I still find Camtasia useful for occasions where FRAPS falls short though, like emulators and stuff like StarCraft.)
Let me just ask one favor of you. If worst comes to worst, do not,
do not get that damn
Unregistered HyperCam 2 shit. I will stab you.
