[Mrtrix-discussion] mrview running with opengl 3.0 ?

[Donald Tournier]

Hi Romain,

Sorry, I just tried to run MRView under OpenGL 3.0, it can't be done. The
shader language version we use requires 3.3, and strangely there is no 3.0
version of it... Sorry.

If you can update your drivers to have OpenGL 3.3, then you should
definitely do it!

Cheers,

Donald.
