D3DRM = Direct 3D Retain Mode (obsolete now)
D3DIM = Direct 3D Intermediate Mode
Thats actually Immediate mode, which is basically what we call Direct3D now, since (I think) retained mode was stopped being worked on in 8.0 apparently (Though still works fine with DX8 drivers).

I didn't see anything about 3D with Omega is what I was basially saying.

And there really isn't a post in here that is offtopic. It's about all the different gaming components for Delphi.
