What? No answers? Weird. It is so easy.
First go to http://www.fraps.com/ (Only works on Full screen downloaded games E.G: Minecraft, Roblox, Wonderland Secret Worlds, Return to Wonderland Platinum / Deluxe Edition.
If you are trying to record a flash game which is NOT full screen or a online game which does not support full screen, Bandicam is handy for recording games like that. go to htttp://www.bandicam.com/ .
It supports even Skype messages and webcam, screen, games and many more. Fraps which I just gave you right now is not for screen recording, online games and Skype webcam and other things.
Bandicam is only capable of recording screen, games and everything but not full screen games.
Fraps is only capable of Recording full screen games.
Whatever you want you can choose.
Both are shorter files, good frame rate and even HD / HQ.
:) Hope this helps!
None requires a webcam ;)
