@Daytona In addition to what Hans states above, allow me to reiterate. The W3D_Gfx driver is allocating VRAM for textures. It does this by allocating BitMaps. However, only the required size in bytes of the texture is passed to the allocator function, not the dimensions or even the format , the allo...

Here is what I believe is happening 1) When querying the maximum texture size, the value supported by the given GPU is returned. This does not imply that your particular card is capable of supporting a texture that size. Note that for 2Kx2Kx4 we need 16MiB. Should not really be problem for a card wi...

@Lio
PS Running Quake2 in CLUT mode will use software rendering. Although the Permedia2 can do 3D operations on 8-bit screens (limited, no shading, 8-bit textures only), There's certainly no support for 8-bit render targets in MiniGL.

@Lio Sorry to hear you are having such sub-optimal experiences with the Permedia2. What I can say is that the Warp3D driver itself is, unquestionably faster than it was in OS3.9 (I have the synthetic benchmarks to prove it), especially for v1-v4 rendering functions. There's no comparison for v5 rend...

Are you able to run the WarpUp version of ScummVM on OS4.1 on the same box? It could be that the 4.1 native version just isn't as optimised. It's a common nuisance caused by people developing on much faster hardware and forgetting those of us on original Amiga hardware. That said, for WarpUp applica...

Can you please post the version numbers for each of the Warp3d components installed on your system? A number of similar colour format bugs were fixed for the Radeon R100 and R200 drivers for the non-interleaved colour pointers previously. Its possible that the interleaved version was overlooked at t...

Note that both compositing and Warp3D make use of the same RadeonCP resource on R200 (and AFAIK also on R100). It's possible that bugs may exist there or that some command packets aren't quite configured correctly. As for poor documentation for Warp3D, its true. Unfortunately that affects driver dev...

I expect the non rendering of triangles in Warp3D with vertices a certain distance outside the viewport may be down to guardband clipping. Unfortunately I no longer have a functioning system to confirm it. There are numerous issues with texture mapping in the R200 driver when multitexturing is not e...

The Envarc:Warp3D drawer contains subdirectories for each hardware driver that in turn allow you to adjust the behaviour of thr drivers, mostly to improve backwards compatibility with software written for older iterations. Most drivers allow you to ajdust these settings for each installed applicatio...

Sad to know you have only an old A1200 ..
Aniway can you release a test version of the library now ?

I presume we can help you with any eventual test

Nothing sad about it. IMHO it will be a sad day when OS4 no longer runs on original Amiga hardware.
