Hello TF2maps.net-ters. I've been downloading a lot of the WIP maps in an effort to reciprocate just some of the awesome help I've gotten from lurking on the boards. However, every map I load locally (including stock valve maps and my own recent creation) causes so much lag that I can't even walk up stairs (I clip through them and am stuck at the same elevation that I spawned on) or jump because the engine never catches up to my actions--or something similar to that effect... Do I have a setting or something wrong? In theory, if I create a game locally I shouldn't have any lag... Thanks for taking the time to read my Q.
