Subject: added separate cl_nopred cvar to use when playing on qw servers since
X-Git-Tag: xonotic-v0.8.5~88^2~5
X-Git-Url: https://git.rm.cloudns.org/?a=commitdiff_plain;h=9ba529f6b88337d1f8ca249a66dc060917e3c3e8;p=xonotic%2Fdarkplaces.git

added separate cl_nopred cvar to use when playing on qw servers since
players expect prediction in quakeworld, now cl_movement is only used on
dp6/dp7 servers.
