Why does it feel so slow???
Did you forget to host_timescale 1 when recording?
host_timescale .25 when recording and 400% speed in post. The map is actually just kinda big. It may be actualy .95 times the actual speed, but not too noticable. I don't record with startmovie n such, I just use shadowplay. So much faster. I'll double check the speed from the demo to the actual video.
Edit: Ok yea, I found the problem, when running the game and recording on that map at 4k, my game was running about 27-30 fps, and I accidentaly had host_framerate set to 30, so any dips in framerate effected the shit out of the recording. I'll redo it and upload a fixed version.
