00d97197db - removed deprecated method to retrieve OpenGL extensions 
Since we force a core profile and this was explicitly disabled for core profiles, this code has no use anymore

fdf324cce5 - fixed error message for old OpenGL versions. There was still a mention of "with framebuffer support" which is core in 3.3. 2018-10-31 10:50:45 +01:00

5f838d52b9 - some cleanup on the OpenGL interface and its flags. 
Most importantly, the separate command line options for switching on the legacy buffer handling have been removed.
There's really no need for them anymore, because unlike in earlier versions many of the implementation differences no longer exist - with the exception of where the light and vertex buffer contents are generated.
For testing this, -glversion 3 is sufficient.

a516210b18 - always retrieve uniform buffer properties. 
They are sometimes needed even if shader storage buffers are available.

9768698eda - do not use SSBOs for dynamic lights on Intel graphics hardware for performance reasons. 
This was already disabled for GL 4.4 and lower but also needs to be done for Intel's GL 4.5 drivers.
Unlike before this is now exclusive to the light buffer, the shadowmap feature is not affected anymore, although that should be impossible to use anyway on all affected hardware due to lack of computing power.

369267bbe9 - adjusted stat code for the new survey. 2018-07-21 19:14:11 +02:00

8ab68264c1 - removal of all code to handle OpenGL 2. From this commit on the main build of GZDoom will be OpenGL 3.3 or higher.

59827cd601 - use layout binding qualifiers on uniform buffers when GLSL version >= 4.2 
This has no performance benefits but allows checking shader generation correctness without having to implement Vulkan first.

3069b53804 - disable shader storage blocks if none get reported for vertex shaders. 2018-05-20 00:16:06 +02:00

c0837f42bd - gl_system.h as well, in particular this has no place in hw_* files. 2018-05-16 23:34:52 +02:00

401c9ab8ca - moved gl_interface.cpp/h to gl_load folder. 
These files are not part of the actual renderer but part of the system code.
This means, for separated modern and legacy GL renderers, there still will only be one set of this, unlike everything else.
