Hi there,

 

i'm currently working on a terrain renderer.

i ran into some performance issues on my laptops intergrated intel graphics card (where terrain is rendered without problems), so i switched to the also available ATI card (where the terrain geometry completely disappears).

Trying to debug my exe with gDebugger, the context tells me there are 61k triangles drawn, but i don't see any.

 

Shaders compile & link successfully.

The VBO (~460kb) & IBO (~57kb) on the card seem to be correct.

 

Posting Code here is difficult since the whole project is a bit larger.

(Link to Github Project: https://github.com/Cracky/XiyaGE/tree/master/src)

 

What else information should/can I provide, to help you, to help me ? ;)

 

Why does the geometry disappear / What can cause these problems / Why does the code work on intels card but not on ATIs ?
