I'm not sure how common this issue is, but I can't seem to capture the video while playing Doom. I use OBS Studio 64 bit, and I can capture the audio just fine, but the video only captures the first frame, basically a screen shot. I'd really like to try and get this resolved if anyone could help me because I'm really eager to start speedrunning this.

My core specs are: Intel i-7 6700k cpu XFX Radeon GTR RX 480 gpu

I have no idea what difficulty to play on. I assume Easy, but I'm not sure. I'm going to learn Any% first I think. Also, besides the scroll wheel, can I rebind anything else?

I want Episodes 1 & 2, NOT Episodes 1 & 2 plus, correct?
