test override_GL_ARB_separate_shader_objects = 1 on AMD

[gregory]

Could someone test this option on latest AMD driver?

This option will force GSdx to use the previously disabled extension GL_ARB_separate_shader_objects. AMD drivers used to be broken with this extension.

Mesa 10.2 will support it (GL, GLES3.1). So I would like to make this extension mandatory for GSdx. It would reduce a bit the complexity of GSdx ogl for me.

So Fedora finally got Mesa 10.2.

It didn't work right. It would just show a small box in the upper right corner of the screen, while the rest went mad.

Weirdly enough, it's in the lower right corner in the snaps taken with F8.

When I force disabled separate shader in advanced config, the problem disappeared.

Sorry it is my fault. I wanted a catalyst driver test. Result is still interesting. I need to check mesa code (nouveau) on latest git.

Finally got my 32-bit fedora on fglrx 14.4.

It worked fine without separate_shader. But when I force-enabled it in the very advanced options, the output wasn't as pretty.
First 2 screens are from Tekken Tag Tournament. The last is the intro to Dark Cloud.

Thank very much for the test. Basically the driver is still broken when both GL_ARB_separate_shader_objects and GL_ARB_blend_func_extended are used...
