Offline games poor performance, Online games, flawless performance.

It was explained to me on the bug tracker that the priority dropping I was experiencing is a design feature so there's nothing I can do about it. It also made me wonder if something else wasn't going wrong. I put this reply on the other post but, so it doesn't get lost in the mix, I decided to start a separate thread to address the performance issue directly without speculating why.

I open IDE, start a single player game of Advanced brutal doom with av.wad, av20.wad and av.deh loaded with it. I changemap to map13 and performance is instantly horrible. It seems spiky too. I get a second or two of OK performance then it seems to ramp up performance lag until I'm at 1fps. I picked level 13 because this is when I noticed it. Now, I conducted a small experiment by loading those exact same files in the exact same order onto a private server, changed to map13, joined the game and performance is as smooth as butter. Framerate is high, no jittering, no stuttering, no drop in FPS with the same exact files. Now could someone please tell me what the hell is happening between my offline games and online that causes such a vast difference in performance?

Just to eliminate IDE as a potential cause, I started an offline game with the same files through a shortcut and performance is exactly the same.
