I have a low-end PC and I have tried different recording software for recording different games. The two software which I think are the best are:-
- FBX Game Recorder
- OBS - Open Broadcast Software
- FBX Game Recorder
FBX is great software by BB Software Inc and the best thing is that it is completely free. It is very simple and easy to use unlike the OBS which a little bit complicated.
FBX recorded my games smoothly on 20fps and the quality is great. FBX is specially made for games and once you press Ctrl + F12 it shows floating small banner which shows the game is recording.
- OBS - Open Broadcast Software
OBS is a multi-purpose video software which is used for live streams and screen recording. This software is also completely free
when I was using OBS I had to optimize many settings in it for recording because the video was lagging and quality was not good. But in the end it worked well. I was also having a problem of black screen in OBS game capture mode so because of that I switched to window capture mode.
Conclusion
I wish I could show you a demo video but I deleted my youtube gaming channel. I think you should give it a try to both of the software. Both have the options to record the games up to 60fps in high quality and both are completely free.
