r4196 | acceptthis | 2013-02-12 19:06:07 +0000 (Tue, 12 Feb 2013) | 9 lines split in/out client frames, so that we can cope with separate packet/movement sequences for nq+prediction. Make default ports a little more explicit. interpolate input frames. should make things smoother when the input rate does not match video rate. fix centering of crosshairs make sure skins are flushed properly on vid_restart, so 24bit skins don't get messed up. keep sounds ticking even when inaudible. qc addressable block now has a max of 2gb. .__variant works as a function argument. NQ clients now receive player physics consistant with QuakeWorld. ------------------------------------------------------------------------ git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4194 fc73d0e0-1445-4013-8a0c-d673dee63da5
