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.
Very useful to compare performance between two builds, check the impact of
a configuration option, etc. FPS log is stored in User/Logs/fps.txt and is
reset each time you launch a game. Only enabled if you check the "Log FPS
to file" option in your graphics settings.
Could be improved a bit: currently logs only every 1s (so you can't really
see small variations), maybe output more infos to the fps.txt like
average/stddev (but Excel/Libreoffice/Google Docs can compute that easily
too).
Reason:
- It's wrong, zcomploc can't be emulated perfectly in HW backends without severely impacting performance.
- It provides virtually no advantages over the previous hack while introducing lots of code.
- There is a better alternative: If people insist on having some sort of valid zcomploc emulation, I suggest rendering each primitive separately while using a _clean_ dual-pass approach to emulate zcomploc.
This reverts commit 0efd4e5c29.
This reverts commit b4ec836aca.
This reverts commit bb4c9e2205.
This reverts commit 146b02615c.
The GL EFB cache did not clamp correctly the coordinates when computing
the rectangle it needed to cache, leading to negative values being used
as indexes and often crashes.
Fixes issue 5510.
please test for regressions, speed and for other issues fixed, as a example, the black color in water splash in super mario galaxy are fixed with this rev.
please as soon as yo find a bug let me know.
To enforce SM2.0 compatibility, the OpenGL plugin was made to crash when
compiling a shader which does not fit in the SM2.0a limits. However, on some
combinations of OS/drivers/GPU, our shaders already do not fit in these limits,
causing artificial failures only to try to keep a non existant SM2.0a compat.
Basically, this sucks.
This commit increases the artificial limit to SM3.0. If you're using a GPU
which does not support SM3.0 and Dolphin works properly, this should not cause
any problem at all.
