You are right, it's a known problem. See DirectDraw7 to Wined3d recent thread, it's related about drawPrimitiveStriddedSlow. We have 3 solutions:
- when app use VertexBuffer: precompilation of VB to be OpenGL compliant
on unlock - using vertex/pixel shaders to do the needed tricks
- for each frame transform all colors in software before rendering
(yuckk)
would you enlighten my, why i was not able to write my own data in the glVertex... method? because this is something precompiled and "source" is already somewhere in the graphics hardware and i can not write data from the heap into it?
because, as you said, it doesn't have the good format. D3D format isn't supported by OpenGL (it's ARGB and we need it to be in RGBA, see D3DCOLOR_* macros on d3d8_private.h)
