Hi , i am new to the Doom speedrunning community and i have a question what kind of source port should i use? I used Crispy Doom but for some reason it didn't work so well while recording , maybe because i was recording with obs and my PC is a sack of shit , so what other source ports should i try? I have a other question . How should i publish my speedrun? I tried recording but the recording were low fps (even tho Doom runs on my PC smooth) i have been using OBS .

I recommend using PrBoom+ and record your gameplay to a demo (.lmp file), instead of recording directly with OBS. Then, you can playback the demo later and use OBS to get the video; when playing-back the video I recommend using glboom (included in the PrBoom+ installation) to play back the demo in OpenGL, instead of the software renderer that prboom uses. OBS doesn't seen to like capturing full-screen applications that use the software renderer, for some reason.

If that doesn't work, I heard there's an option to have prboom directly output a video file without even using OBS. Not sure how that works because I've never used it myself, look around for more info.

Also check this post in the doomworld forums, there's more information on how to get PrBoom+ to record demos and other stuff: https://www.doomworld.com/forum/topic/18410-welcome-to-the-demos-forum-prboom-plus-usage-wad-and-irc-links-general-info/?tab=comments#comment-535005
