+Performance tips for software rendering:
+</P>
+<ol>
+
+<li> Turn off smooth shading when you don't need it (glShadeModel)
+<li> Turn off depth buffering when you don't need it.
+<li> Turn off dithering when not needed.
+<li> Use double buffering as it's often faster than single buffering
+<li> Compile in the X Shared Memory extension option if it's supported
+ on your system by adding -DSHM to CFLAGS and -lXext to XLIBS for
+ your system in the Make-config file.
+<li> Recompile Mesa with more optimization if possible.
+<li> Try to maximize the amount of drawing done between glBegin/glEnd pairs.
+<li> Use the MESA_BACK_BUFFER variable to find best performance in double
+ buffered mode. (X users only)
+<li> Optimized polygon rasterizers are employed when:
+ rendering into back buffer which is an XImage
+ RGB mode, not grayscale, not monochrome
+ depth buffering is GL_LESS, or disabled
+ flat or smooth shading
+ dithered or non-dithered
+ no other rasterization operations enabled (blending, stencil, etc)
+<li> Optimized line drawing is employed when:
+ rendering into back buffer which is an XImage
+ RGB mode, not grayscale, not monochrome
+ depth buffering is GL_LESS or disabled
+ flat shading
+ dithered or non-dithered
+ no other rasterization operations enabled (blending, stencil, etc)
+<li> Textured polygons are fastest when:
+ using a 3-component (RGB), 2-D texture
+ minification and magnification filters are GL_NEAREST
+ texture coordinate wrap modes for S and T are GL_REPEAT
+ GL_DECAL environment mode
+ glHint( GL_PERSPECTIVE_CORRECTION_HINT, GL_FASTEST )
+ depth buffering is GL_LESS or disabled
+<li> Lighting is fastest when:
+ Two-sided lighting is disabled
+ GL_LIGHT_MODEL_LOCAL_VIEWER is false
+ GL_COLOR_MATERIAL is disabled
+ No spot lights are used (all GL_SPOT_CUTOFFs are 180.0)
+ No local lights are used (all position W's are 0.0)
+ All material and light coefficients are >= zero
+<li> XFree86 users: if you want to use 24-bit color try starting your
+ X server in 32-bit per pixel mode for better performance. That is,
+ start your X server with
+ startx -- -bpp 32
+ instead of
+ startx -- -bpp 24
+<li> Try disabling dithering with the MESA_NO_DITHER environment variable.
+ If this env var is defined Mesa will disable dithering and the
+ command glEnable(GL_DITHER) will be ignored.
