Subject: added r_transparent cvar to turn off transparent rendering for
X-Git-Tag: xonotic-v0.6.0~163^2~469
X-Git-Url: http://de.git.xonotic.org/?p=xonotic%2Fdarkplaces.git;a=commitdiff_plain;h=5d0d1ba365ad6a2cb0e67cd7a4f26f1c1247bd0d

added r_transparent cvar to turn off transparent rendering for
performance testing
added r_deformvertexes cvar to turn off deforms for performance testing
neither of these settings are meant to be performance improvements, only
testing methods
