Using RadeonHD/Warp3D for Southern Islands cards on X5000

[elfpipe]

I am trying to get Wipeout running on X5000 with RadeonHD 7700. I am using the SI Warp3D driver from AmiStore.

To get 3d graphics working, I have to do a custom build of Warp3DPPC.library (rewarp), that disables the z-buffer (which means just returning W3D_SUCCESS in W3D_AllocZBuffer and W3D_ClearZBuffer).

This of course garbles the graphics, although it runs at a very satisfying speed.

Can you help with ideas how to bring this solution further?

Isn't NovaBridge filling in this gap?

Besides, warp3dppc.library is just a wrapper to the OS4 warp3d.library.

This is the first WipEout, right?

Normal allocating and freeing zbuffer goes through w3d_Picasso96.library (at least with the old Warp3D) with W3DGFX_AllocVMem/FreeVMem.

Clearing is HW specific

Yes. I was unable to get it, so I wanted to try alternatives. Very interesting.

Yes. Actually there is one usecase, where it makes a lot of sense. When using nova, you can't get fullscreen in wipeout. By spoofing 32 as 16 bit in Warp3DPPC.library, you can get it working.

Normal allocating and freeing zbuffer goes through w3d_Picasso96.library

(at least with the old Warp3D) with W3DGFX_AllocVMem. I know too little about it to evaluate, what that means. But there is definitely a problem with the z-buffer when using "classic" Warp3D+SI driver. The triangles are not organized right, and there are big areas unrendered.
