I suspect some other problem as G450 certainly does support a depth buffer. No modern card, as of '97 or so, lacks this support. Even scene-capture cards, ala Kyro, perform depth-buffer operations.

The default values are as follows: depthSize : 16 doubleBuffer : REQUIRED sceneAntialiasing : UNNECESSARY stereo : UNNECESSARY redSize : 2 greenSize : 2 blueSize : 2 --------------------------------- Calling tmpl.setDepthSize(0) for the template will do. It seems that Matrox G450 does not support depth buffer.
