marcooder...

it seems that I have a major problem with OpenGL graphics, beyond my limited IT skills, so I'm asking for some help and advice here.

Basically, I get the OpenGL rendering context - the gray background; I can change its colour, but nothing else works, like videoplanes, 3d objects (like plato), 3d text and so on. Not even the jitter tutorials.

my openGL version should be fine (2.1): I tested it using OpenGL Extensions Viewer, and this is the report of the passed test (graphically everything was ok):

Renderer: AMD Radeon HD 6770M OpenGL Engine

Could anyone point me to where the problem could be?

without seeing a patch, there's really no way to know.

for example, jitter tutorial 30 (the first, I think, involving OpenGL) doesn't work properly: it doesn't show the 3D text nor the axes, nothing actually. Apart from the gray background.

here's a patch of mine which doesn't work, but, since I could never get OGL to work, there's no way for me to tell whether its code is right or wrong:

are there any error messages reported in the max window?

Hi, no I don't get any message in the max window, apart from "jitter initialized".

Is there anything i could try before completely reinstalling it?

i would update to the latest version of max
