We’re doing a new segmented speedrun of RtCW single player, but we have hard time finding the best way to record it. First we couldn’t record demos at all, it said “the server must have g_synchronousclients 1 set for demos” which crashed the game if put to 1. There was another similar command (same command without H) that allows demo recording, but demo playback crashes game again, giving error: “VM_Call with NULL vm”.
We can’t really use Fraps or similar program to do it either, since we have different players with different computers/resolutions and combining the video would be impossible to make look good.
