ARB_shader_texture_lod is a requirement for SM3 support. If the driver doesn't support that while the hardware can do it, you should probably file a feature request with NVIDIA. Note that the driver you're using is fairly old though. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

Even most new. Even with up-to-date drivers. And there is no standard demanding it to be the requirement for shader model detection. So it is just working wrong. And opengl does not follow Shader Model format. And it's not working as requirement, because actually new Nvidia videocards are satisfying gl_info->supported[EXT_GPU_SHADER4] condition, not ARB_shader_texture_lod. Even 7900gs is not passing this check. Only SM4 nvidia videocards could pass this condition! I would so happy, if NV_vertex_program3 check were restored, so nvidia 7 series cards shall be recognized by wine as SM3 compatible without tricky manual patches. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.

As said in Comment #6 GeForce 6/7 series cards do not support ARB_shader_texture_lod, but they are SM3.0-compatible. The hardware is, but the nvidia GL drivers don't expose the required functionality. You need either ARB_shader_texture_lod, EXT_gpu_shader4 or GLSL 1.30 to implement the SM3 texldd and texldl instructions. The hardware clearly can't support EXT_gpu_shader4 and GLSL 1.30, but it could do ARB_shader_texture_lod if nvidia implemented it in their drivers.

Are you sure that SM3.0 that ARB_shader_texture_lod is required for supporting SM3.0? For example, patching wine for disabling that commit (http://source.winehq.org/git/wine.git/commitdiff/c51db63ba4eda7e2cb565ebadf5...) gets running EVE Online with SM3.0 And I'm not sure that checking ARB_shader_texture_lod is the best method for checking SM3.0 NVidia (http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0...) recommends do it with NV_vertex_program3: "In OpenGL, all you need to do is check for the presence of the NV_vertex_program3 extension. If you are using the GLUT library, the glutExtensionSupported function can perform that check. The number of supported vertex texture images is queried as follows: glGetIntegerv(MAX_VERTEX_TEXTURE_IMAGE_UNITS_ARB, &vtex_units);" I don't know what functions are available in the NV_vertex_program3 (http://www.opengl.org/registry/specs/NV/vertex_program3.txt), but maybe better will be giving Nvidia to correct their drivers? If we hide this driver error in the Wine code, it will never be fixed.

Well, you can get lucky if the application doesn't actually use texldd or texldl in fragment shaders. Many SM3 applications don't, but that doesn't mean we can report the capability if the driver doesn't support it.
And I'm not sure that checking ARB_shader_texture_lod is the best method for checking SM3.0 NVidia (http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0...) recommends do it with NV_vertex_program3:
That's for vertex shaders, the specific issue is with texldd and texldl in fragment shaders. More importantly, that extension is for NVIDIA's proprietary NV_vertex_program / NV_fragment_program extensions, it doesn't do anything for GLSL shaders. That said, if the driver supports the NV_fragment_program2 extension, you should indeed get SM3 if you disable the GLSL shader backend and use the ARB program shader backend instead. Note that that configuration is mostly unsupported though. Something else to consider may be using the Nouveau drivers instead. I'm not entirely sure what level of support it has for GF6/7 hardware at this point, but there's a decent chance it either already supports ARB_shader_texture_lod, or could be made to relatively easily. -- Configure bugmail: http://bugs.winehq.org/userprefs.cgi?tab=email Do not reply to this email, post in Bugzilla using the above URL to reply. ------- You are receiving this mail because: ------- You are watching all bug changes.
