GSdx-ogl speed increase

Which GPU. Is it well supported on Mesa?

Edit: I know I take liberty with the spec. Normally I must ensure I can write data. In worst case I will only expect drawing corruption.

I'm using an A10-7850k, I'm not really sure how well supported it is by mesa though. The last time I had a lock up like this with mesa was with my previous richland apu when running various steam games for example brutal legend, and the cave both did the exact same thing. I haven't really had any issues like this since I upgraded.

Ok. Thanks for the test. If someone have an intel gpu, it is time to shine

Anyway, I need to finish a pending work on a special alpha test slowdown. Once done I will get back to this storage extension with a proper synchronization mechanism. Maybe it will work better.

I decided to try the fglrx driver to see if maybe that one works. It doesn't crash like mesa, but all I get when I start a game is a green to red gradient from the bottom left to top right.

Ok if you have latest catalyst could you give me the output of glxinfo. I want to check the support of gl 4.5 extensions

It misses the interesting part the extension list

Please retry. I updated the code. I hope it will work.

Edit (try with either small upscaling or big upscaling)

I think I'm running into a different bug that is causing the crash on mesa and the gradient on fglrx. Every time I build with the --debug switch on current master I get those errors even with ogl_vertex_storage set to 0. When I build with the --release switch pcsx2 works and setting ogl_vertex_storage = 1 works on master. I'll see about doing some benchmark tests tomorrow.

Hum, I maybe found the root cause. I need to change some code.
