to use VAO, we must use VBO, so some legency code was removed:
- ARB_map_buffer_range must be available (OGL 3.0), don't call glBufferSubData if not
- ARB_draw_elements_base_vertex also (OGL 3.2), else we have to set the pointers every time
- USE_JIT was removed, it was broken and it isn't needed any more
And the index and vertex buffers are now synchronized, so that there will be one VAO per
NativeVertexFormat and Buffer.
change naming in all the backends vertex managers to make more easy to continue with the merge an some future improvements.
please test this as i'm interested in knowing the performance in linux and windows with the different hardware platforms.
So to compensate lets bring back some speed to the emulation.
change a little the way the vertex are send to the gpu,
This first implementation changes dx9 a lot and dx11 a little to increase the parallelism between the cpu and gpu.
ogl: is my next step in ogl is a little more trickier so i have to take a little more time.
the original concept is Marcos idea, with my little touch to make it even more faster.
what to look for: SPEEEEEDDD :).
please test it a lot and let me know if you see any problem.
in dx9 the code is prepared to fall back to the previous implementation if your card does not support the amount of buffers needed.
So if you did not experience any speed gains you know where is the problem :).
for the ones with more experience and compression of the code please test changing the amount and size of the buffers to tune this for your specific machine.
The current values are the sweet spot for my machine.
All must Thanks Marcos, I hate him for giving good ideas when I'm full of work.
implemented buffer format fall back to allow hardware that don't support lockable formats to run the games with Z peeking disabled, applied as well the patch suggested in issue 1494 please give heavy test to this commit
