up sv_clmovement_maxnetfps to 120, as the worst case issue - falling through solid - no longer can happen. Still gets lots of "unstuck entity" spam messages at high netfps on certain angled slopes due to an old collision bug (trace.endpos sometimes being inside solid when the trace ended very close to solid) which has to be fixed
