GSdx-ogl + nouveau + 260GTX + mesa 11.2.2: buggy driver detected

[Soukyuu]

Testing how pcsx2 would run on nouveau to work around #1355 and I'm getting

Buggy driver detected. Geometry shaders will be disabled
Buggy driver detected, GL_ARB_separate_shader_objects will be disabled
Note the extension will be fixed on Mesa 11.2 or 11.1.2.

Well, my mesa version is already 11.2.2, I guess it didn't get fixed?

Overriding doesn't seem to do anything, the text in ar tonelico 2 is lacking any alpha, so it's all blocks. At least it runs better than with the nvidia blob in hardware mode...

Geometry shader has only an impact (positive or negative) on the speed. Maybe it is a gui issue. Check GSdx.ini file. -1 means auto, 0 disabled, 1 enableed.

Could you post a screenshot of a AT2. It could be a gsdx bug when I made the copy to legacy repository.

[gregory38]

Oh by the way, you don't need to use the legacy branch with nouveau. You could use the full and latest version.

[Soukyuu]

Same on non-legacy branch:

edit: but the "buggy driver" message is gone

[Soukyuu]

The text issue is fixed by setting blending unit accuracy to anything above basic, but the black areas around text boxes and other textures stay even if I go up as high as Ultra.

[gregory38]

Could you post your current GSdx.ini file.

[gregory38]

My guess is a bad setup of accurate date or the extension load_store_image shader.

[mirh]

Couldn't it have something to do with how NV50 driver still lacks Geometry shader instancing and multiple streams ?

Also, I can't understand why mesa_amd_buggy is triggered by nouveau.

[gregory38]

1/ you won't win with a random keyword ;) Those features aren't used. So it is either a bad conf or a bug in the driver 2/ both driver, due to gallium, often shares the same bug. Beside the detection is done with the vendor string name. I don't run an opengl testsuite to detect working driver ;) It was a temporary solution anyway.

[Soukyuu]

Accurate date requires openGL 4.2 (or at least it says so) and I don't have that (3.3 only).

GSdx.ini.txt

[Soukyuu]

Should've posted this too, probably:

[gregory38]

Hum. Did you enable safe fbmask hack? Please try without it. (I don't remember if the gui checkbox still exists, otherwise delete the line in the ini) If you still have issue, could you try to generate an apitrace trace. This way I could replay it on my side and confirm the driver bug.

[gregory38]

And it might worth to check accurate date. It could partially work with your gpu.

[Soukyuu]

Right, I did set that flag. But that was me trying to test if it would go away if I did - it doesn't affect anything though.

I also tried accurate date, no change. Here is the apitrace: click

[gregory38]

Could you replay the trace on your side, to be sure you do have the issue on the trace.

Edit: trace was generated on the SW renderer. Do you have the bug on HW or SW renderer?

[Soukyuu]

Yes, it did. It also shows an error message in the terminal:

[gregory38]

Ok. I have the bug.

Edit: I will try to fix it for tomorrow.

[gregory38]

Please try latest git.

[Soukyuu]

Yes, that fixed it, thanks!
