1) Whenever I open OBS after opening Desmume (NDS Emulator), windows will change the theme to Windows 7 Basic which will interfere with my OBS scene. Is there a way to prevent this?

2) Whenever I use OBS to stream Desmume, Desmume starts to slow down. Anyone knows of a solution to prevent this from happening?

Argh, I was going to test all the emulators, I keep getting behind on everything.

I'd have to see a log file to see what capturing you're doing with desmume. Also you don't have OBS set to disable aero do you? Though I take it you're implying that's not the case. Emulators can use a lot of CPU, though it's just a DS emulator so it shouldn't be anything significant.

I have disable aero unchecked.

Ah, okay, I don't know about aero disabling -- that might be just caused by the drivers.

But as for the emulator slowing down, I think I see the problem. Emulators use a lot of CPU. However, encoding video also uses a lot of CPU. So most likely what's happening here is insufficient CPU, as your computer only has two physical cores, and it's causing the emulator to slow down.

The way to fix this is by either turning down the FPS and/or resolution of OBS (via downscale), or by turning the x264 CPU preset to superfast or ultrafast (though quality will be less). I'm fairly sure that's what you'll have to do in the case of an emulator, as emulators use quite a bit of CPU (especially for a more modern system like the DS)
