Re: Low FPS when using OBS monitor capture but not game capt
Yea i didnt mean to say that its UNUSABLE, with aero off its decent~ish with a powerful CPU. I just can talk about my experience with my old amd x6 at 3,8ghz and with that monitor capture was semi-terrible compared to gamecapture (7850DD as GPU). Never got a chance to test it with my new intel i7 2700K but im pretty sure with such a CPU it would be fine.
Gamecapture uses the gpu instead so if you max out your gpu with the game alone it wont perform as well, you might want to try and limit your ingame fps (vsync or other means to limit it). That SHOULD be the only reason that gamecapture would perform worse in your case.
@OP: To capture your desktop monitor capture is totally fine in any case. You could always create 2 scenes and toggle between them with hotkeys or the simple scene switcher plugin in the plugin section of the forum. 1 scene with gamecapture for ingame and one for the desktop (many league of legends people do that to capture the lobby which is seperate from ingame).
