I am sorry I forgot to introduce myself.

I am a software engineer at AMD, working on OpenGL graphics driver, I am working with wine issues now. Some uses complained that there are too many issues to play games with wine with AMD graphics card, so we want to improve the quality.

That’s all, Thanks

Regards

Sunny

Subject: about video memory detection in wine

You are using the hardcoded method to get the vidmem now (in function IWineD3DImpl_FillGLCaps), first you call glGetString(GL_RENDERER) to get the GPU renderer string, and then you use this string to set the vidmem in your code. Unfortunately you don’t get all of the ATI GPU’s string now, for our workstation GPU, the string is always like “ATI FireGL V8700”, so you don’t recognize this GPU and consider it as ATI_RADEON_9500, then 64MB is set which doesn’t support 1280x1024 resolution (Out of adapter memory).

I think you can first detect GL_ATI_meminfo in glGetString(GL_EXTENSIONS); if GL_ATI_meminfo exists, then you can use glGetIntegerv(GL_VBO_FREE_MEMORY_ATI, param) to get the current free video memory, you can see more info at:

http://www.opengl.org/registry/specs/ATI/meminfo.txt

if GL_ATI_meminfo doesn’t exist, you can fall back to the original method.

Please tell me if you have any questions.
