Hey guys.
Whenever you alt tab, and your graphics get all screwed up, you don't have to restart TF2 anymore.
Here's all you have to do:
1) Put this into your autoexec.cfg
Alias altabfix "record bugfix; wait 15; stop"
bind "F9" "altabfix"
2) Whenever there's a graphics glitch after you maximize TF2, just hit F9 and it will be fixed.
The method that is used, is a demo is started then stopped immediately, allowing the video to re-sync and the models will all become correct.
