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: https://git.rm.cloudns.org/?a=commitdiff_plain;h=b941207315be4d71624526b275cb98e261617457;p=xonotic%2Fdarkplaces.git

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
