Performance issues with EXT_point_parameters & quake2
-Broken drivers:
- --> After integration of the changes in kw3, only the X and FX
-drivers are known to work. Windows and D3D are known to be broken,
-and all others are suspected to be broken. Please test your driver
-and update this entry when more is known.
+Using glPolygonMode() where the front and back modes aren't the
+same causes poor performance on 3Dfx.
-Separate specular color interpolation isn't implemented for points and
-lines. Also, will have to add specular color add to pb.c (pixel buffer
-code).
+Broken drivers: some of the Mesa device drivers (such as BeOS, D3D,
+etc) haven't been updated for Mesa 3.3's device driver changes.
+
+glDrawRangeElements() should use vertex array locking to improve performance
+but trying to do so causes a rendering error. Reported by Scott McMillan.
+Fixed by disabling locking in glDrawRangeElements (varray.c) but that's
+really just hiding a bug in array locking.
