if i had a vote it would be yes. i can understand knowing appoximately where enemies are through radar usage, and i can even see the occasional prefire because of it. i do that sometimes. when i just KNOW a guy's gonna be there via radar and/or footsteps, sometimes i'll prefire. however the frequency, accuracy, and walltracing to me just looks like it could be nothing but hacks. if it helps, i prefer r_drawothermodels to mat_wireframe because you can still see the boxes fully intact. overall, if this sort of thing happened occasionally i'd say meh, but the precision he shows in walltracing and prefiring WITH CONSISTENCY is enough for me. walls are tough to catch, and tougher to prove, but this is one of the stronger cases i've seen.
