Subject: fix a serious issue with CSQC frametime being non-zero on both calls
X-Git-Tag: xonotic-v0.8.0~96^2~76
X-Git-Url: http://de.git.xonotic.org/?p=xonotic%2Fdarkplaces.git;a=commitdiff_plain;h=b941207315be4d71624526b275cb98e261617457

fix a serious issue with CSQC frametime being non-zero on both calls
when using stereo rendering, it is now zero on the second eye so that
frametime does not lie
