When TF2 loads the same map a second time, it's much faster. I'm guessing this is because TF2 keeps that map in memory or something like that. But I want to stop it because i'm testing a map, so I want to be able to alt-tab out of TF2, make changes, recompile, then alt-tab back in and run the map. However i can't do that as TF2 will run the old version of my map from memory, not the new compiled version on the hard drive. At the moment i have to restart tf2 every time, which takes ages.
