But I will attend at the swedish wcg finals as a organizer not a player =)

Hi,

At the end of the day, Most, if not all Directx functions can be run in software mode. Even the vertex and pixel shaders can be run on the CPU instead of the GPU. (See the Wine Directx -> OpenGL wrapper for the way they are currently emulating the shaders)

Yes this will most likely be slower, but once cxbx can actually run games, what's to say that the functions can't be added to run on low end graphics hardware as well. At the end of the day you pick your CPU/GPU and you take the framerate and features that provides.

But I won't disagree, the faster the card, the better it will go...

So, in other words, there's a VERY high chance we'll see XBOX emulation (at a decent stage) before ANY other system emulation.

Since Xbox is a DX8 part, and not DX9 any card that full supports DX8 should work fine. remember the GPU in xbox is basically a geforce3 with an extra vertex shader.

Well, caustik is using a Radeon 7000 series to develop CXBX on... It might be tough emulating some of the more complex features and graphics that his card does not support.

However, Radeon 7000 is a purely DX7 card. No shaders.

The XBOX GPU is the NV2A chip, the closest PC chip is the NV25 used in the Nvidia GF4-TI.

The GF4-TI is DX8.0 compliant, and has hardware support for Pixel Shaders (PS) 1.0/1.1/1.2/1.3 and Vertex Shaders. The ATI 8500/9000/9100/9200 is DX8.1 compliant, and has hardware support for PS 1.0/1.1/1.2/1.3/1.4 and Vertex Shaders. The GF-FX 5200/5600/5800/5900 should be DX9 compliant, but due to lack of full support in the drivers, is not. They support PS 2.0 and all lower levels (1.x). The ATI 9500/9600/9700/9800 is DX9 compliant. They support PS 2.0 and all lower levels (1.x).

Vertex Shading can effectively be emulated by modern CPUs of moderate speed. The SIS Xabre 400 cards support hardware PS, but use software-based VS.
