|
|
|

<li>Entirely new Shading Language code generator.
|
|
|
|
|
<li>Much faster software execution of vertex, fragment shaders.
|
|
|
|
|
<li>New vertex buffer object infrastructure (replaces old array_cache code).

|
2007-03-21 17:57:30 +00:00
|
|
|
<li>GL_MAX_DRAWBUFFERS is now 4 (software rendering) so
|
|
|
|
|
"multiple render targets" are really supported.
