Subject: replaced qglArrayElement calls with qglVertex3f calls in showtris code,
X-Git-Tag: xonotic-v0.1.0preview~3274
X-Git-Url: http://git.xonotic.org/?a=commitdiff_plain;ds=sidebyside;h=79fe0dd492780925625f3c408ac6db1898b05b45;p=xonotic%2Fdarkplaces.git

replaced qglArrayElement calls with qglVertex3f calls in showtris code,
this avoids issues with abysmal gl_vbo 1 performance on NVIDIA cards
(which seem to use a software fallback for drawing lines for some
reason)
