I have a terrible computer, first off. I've tried Avast!, which records my desktop well. As for games, it skips a lot or fast forwards. Fraps is good, but it drops FPS a lot. Bandicam is laggy. Any good softwares that can actually record games on a horrible computer? :/
Try changing the setting on all to record at a lower fps. If not, I guess try OBS, I heard that is good.
I tried putting Avast at lowest settings. When I record with OBS it freezes the recording and stops early. :( I can't use the Windows 10 one, because I'm on Windows 8.1 and to me it's easier to use.
