Question / Help Any way to not lose FPS when using Monitor Capture?

[Robbie]

Currently playing around settings and I noticed that if I use Game Capture to stream the game I get no fps drop whatsoever but if I stream using Monitor Capture I go down from like 60-70 fps to around 30 fps in games. I have Aero disabled.

No, monitor capture is awful and shouldn't be used.

For what it's worth, monitor capture works fine in Windows 8. Windows Vista/7 users should indeed avoid it like the plague, however.

I see, thanks for the replies. What would I have to do if I wanted to play 2 games at the same time (for example playing Osu during a que time) without having to constantly turn the game capture for Osu off after the que is done and whatnot so it doesn't stay on top of the main game I play? So whichever game I'm currently tabbed into appears on top.

Might be a dumb question but can you explain why Monitor Capture on Windows 7 is "awful" and not recommended? If that's true, then why is it in OBS at all?

Also, a question regarding game capture.....is it recommended to start the game first *then* start OBS, or should I start OBS first then start the game?

 

[R1CH]

Sometimes monitor capture fits the use case (eg if you're streaming a painting / drawing / programming show) and FPS is not important. Also for certain programs, it's the only method that works.

Game first is recommended, this way it won't randomly disappear if you open the game capture source properties.

If you're on Windows 7 and the game is running in Windowed mode or Borderless Windowed mode, you can probably use DWM capture instead of Monitor capture. Just add a game capture and select "DWM Monitor Capture" as the application. (Note that Aero has to be enabled for this to work, and it will only capture your primary monitor.)

That worked perfectly thanks.

Sorry to bother you guys again, The DWM monitor capture was working great till I restarted my PC. After I restarted my PC, using DWM always gives me a black screen for some reason. I have looked through some videos that talk about black screens but none of it has worked or was relevant to me.

My video adapter is set to my nvidia graphics card, everything I play is non-full screen (it's still a black screen even when I try to stream my desktop alone). I also have no drop down box when I try to add OBS at my nvidia settings but I guess that only applies to laptops.

Here is my log of the stream I just attempted.

Edit: I restarted my pc again, it started capturing my monitor but I restarted another time just to make sure and it turned into a black screen again. Could this be something to do with my dwm.exe?
