E1M4 Tyson demos I record keep desyncing. I tried twice so far, both demos go out of sync within the first 30 seconds.
I use Ultimate DOOM 1.9 WAD with CNDOOM 2.0.3.2, here's the command line I used to record the demo:
Hmm, can you try to record demo with chocolate doom v2.0 and see if it still desync? I will try to look into it but does not promise anything. I'm aware that 2.0.3.2 has some serious issues with mouse and graphic. Also try to record with 2.0.3.1 if you are willing to waste some time to bug this out.
I looked into it a bit, and your config is a bit weird so please delete your config and create new one with setup. I've tried to record several demos and I didn't have any issues. So first, try with new config. Second, I need you to pinpoint second when demo started to desync.
Seems like it's a Chocolate Doom issue - it happened in Chocolate Doom 2.2.1 too. I guess I should create an issue at Chocolate DOOM GitHub then.
I'll try a different config later though, just in case.
A new config solved it, but it's pretty weird because my configs for Chocolate Doom and CNDOOM are completely unrelated.
Anyway, I've got a new config all set up and it seems to be working fine.
