OpenGL 3.3 renderer rewrite

[NaN]

Requiring GL3 features effects would really suck for anyone using opensource drivers

Are open source drivers able to run current shader path?

There's a pretty high chance that a sizeable chunk of the GL3/4 specs will never be included in Mesa3D because of patent issues.

There's a pretty high chance that Mesa3D won't be able to run any sufficient complex 3d game at playable frame rates. Given that 3d speed is not even a priority for the developers: "From a high-level RedHat point-of-view we aren't interesting in gaming level drivers. ..."

re-write the renderer (again? didn't this happen somewhat recently?)

As long as nobody gets hurt and we get rid of some of the restrictions of the current one, why not?

you may as well adopt Ogre or another decent graphics engine.

There is an Ogre implementation already: http://vdrift.net/Forum/viewtopic.php?t=1316

It would be cool if we had some minimal graphics interface to allow for multiple renderer implementations(GL3, GL2, ...). Something like being able to upload some vertex attributes, textures and pick a shader/rendering layer.
