gsdx ogl: various minor optimization. * move most of gl states into a separate namespace. Extend it to depth/stencil/blend micro state => save 10,000 opengl call by frame for colin mcrae 3 * Only setup blend state of first drawbuffer * Don't request anymore a debug context on dev/release build git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5713 96395faa-99c1-11dd-bbfe-3dabce05a288

gsdx ogl: Test the ARB_shader_subroutine GL4.0 extension The idea was to replace shader program swith by pointer function calls inside shaders. At least parameters that are often changed between draw call. So far I only ported atst and colclip. Unfortunately code is "slower" (on GSdx standalone). For the moment keep the code but disabled. If I understand well the validation of program is done in the "driver thread" but the additional call are done in the overloaded MTGS thread. Apitrace profiling shows faster GPU draw calls. Another possibility is that the driver still need to validate the draw call because of others state change. Here some stats on colin3 (90 frames): without subroutine: UseProgram 125246 with subroutine: UseProgram 2906, subroutine 125945 => 3605 extra calls overhead (not all parameters are ported to subroutine) git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5715 96395faa-99c1-11dd-bbfe-3dabce05a288

gsdx ogl: Flush various pending work * try to use more subroutine on VS&PS, unfortunately hit a driver crash! * Call Attach/DetachContext through GSDevice so I can unmap currently mapped buffer * Implement glsl part of GL_ARB_bindless texture, again hit another driver crash! * various fix of GL_ARB_buffer_storage. Basic benchmark show only improvement on 'cold' case, I guess it will improve smoothness * try to fix GL_clear_texture, no success so far. It seem the extension is limited to basic texture (aka no depth/stencil) git-svn-id: http://pcsx2.googlecode.com/svn/trunk@5752 96395faa-99c1-11dd-bbfe-3dabce05a288
