I'm having serious troubles with my d3d app (DirectX 6.1 interfaces), especially with Voodoo2 cards
First, the IDirect3DViewport3::Clear2 doesn't work when used with D3DCLEAR_TARGET (and I'm not too sure about the ZBuffer, since I get very strange ZBuffer artifacts, but not in *every* frame)
my app is quite simple at the moment
it draws a picture in the background using D3DTLVERTEX's as seen in many sdk samples
then I draw some triangles (with star texture) on top of it. Now on some areas they seem to be overlapped by the background, on some they are in front of the background, though they are coplanar
Hope someone can help me,
and Merry Christmas !
