Trouble with OIT and Mesa 18.2 git

[MastaG]

I'm currently building the OIT version of reicast with: DEBUG := 0 NO_REND := 0 HAVE_GL := 1 HAVE_OIT := 1 HAVE_CORE := 0 NO_THREADS := 1 NO_EXCEPTIONS := 0 NO_NVMEM := 0 NO_VERIFY := 1 HAVE_GENERIC_JIT := 1 HAVE_GL3 := 0 FORCE_GLES := 0 STATIC_LINKING:= 0

However when I run reicast it fails with: [code][libretro INFO] Using Recompiler Sh4 Reset recSh4 Init Freeing fpcb Shader: failed to compile 0:1(10): error: GLSL 4.30 is not supported. Supported versions are: 1.10, 1.20, 1.30, 1.00 ES, 3.00 ES, 3.10 ES, and 3.20 ES

Failed shader source: #version 430[/code]

I think it only shows the OpenGL ES profiles somehow? I can verify that it links with libGL though.. [code]libGL.so.1 => /lib64/libGL.so.1 (0x00007fbaeae2c000) libGLX.so.0 => /lib64/libGLX.so.0 (0x00007fbae9acb000)[/code]

When I change the Makefile for OpenGL Core profile support, by setting: HAVE_CORE to 1 Reicast will fail with the following message: [code][INFO] [Wayland]: Setting buffer scale factor to 2.

You need to likely define both HAVE_CORE and HAVE_OIT since Mesa Intel only supports GL 3.0 max for compatibility contexts, so you likely need core profile.

[inactive123]

@flyinghead Do you know why fogging appears broken when using a core profile for OIT renderer instead of a compatibility context?

See this pic as an example -

[inactive123]

@MastaG I updated RetroArch so that hopefully it should no longer fail on gl_FragColor when compiling the menu shader pipelines for GL core profile. Apparently this is only a deprecated warning on Nvidia GL drivers while it is an error on Intel Mesa drivers.

[MastaG]

@twinaphex yes that fixed it :) Updated both retroarch and reicast-emulator to the latest git. I've built reicast with both HAVE_IOT and HAVE_CORE enabled (as Intel indeed doesn't have compat-profiles yet like the radeon gallium3d driver).

Now the only problem when I run it, is that many textures aren't rendered correctly. They are either white or black.

Here's the full log: https://pastebin.com/DCJus3JE

See some screenshots of Sonic Adventure2

[inactive123]

Yeah, I have numerous graphical issues too with HAVE_OIT=1 and HAVE_CORE=1 both enabled. @flyinghead would likely be the only person to know how to fix these issues.

I still think in both these cases, it's fog table-related.

[flyinghead]

Yeah, if I disable the fog it seems to work. Pardon my ignorance but what does the HAVE_CORE=1 option do? Is it something that's handled by the RA frontend?

[inactive123]

HAVE_CORE makes the libretro port use a core profile for setting up GL4.3 instead of relying on the implicit compatibility context. Mesa Intel does not support GL 4.3 with the compatibility context.

[inactive123]

See this -

https://github.com/libretro/reicast-emulator/blob/master/core/libretro-common/glsm/glsm.c#L2819

[flyinghead]

Got it: GLES only supports alpha for single-channel images, while GL core only supports red. Here is a fix to backport: https://github.com/flyinghead/reicast-emulator/commit/bb2d860902f26734008cd7556190960e3f418c52

[inactive123]

Backported the commit and made core profile for GL 4.3 the default now for Reicast OIT instead of a compatibility context -

https://github.com/libretro/reicast-emulator/commit/fc8eb6db0484def28291466f3d03d305db1098bc

Hopefully things will work fine now for @MastaG in the next subsequent buildbot build.

[MastaG]

@twinaphex @flyinghead Using retroarch rev: 5159f71cf5aeb5b89e0860fd630bef9bb8f8179b and reicast rev: fec826ebd9c249c270ae8bc1ba28d31230363b31

It seems to render Sonic Adventure 2 now perfectly without any glitches :) This is with HAVE_OIT and HAVE_CORE enabled.

Thanks alot, this is very nice, as only the closed source amd/nvidia drivers implemented OpenGL compat profiles. (the radeon gallium driver as well, but only in Mesa git so far).

This means the Lakka/Recallbox/Batocera.linux/whatever PC-linux builders can now target HAVE_CORE and OIT as this should work for all OpenGL drivers.

Only minor thing is that it seems to run too slow for some reason. Like 3/4 of the speed. But that will require some more tweaking on my side I guess, or perhaps my notebook is just too slow. i7-6600U @ 2.60Ghz with Intel HD Graphics 520 (Skylake GT2) running Mesa 18.2 (git weekely updated).

Thanks for now!

[MastaG]

Alright, figured out the slowdown as well. According to RetroArch the estimated refresh rate would be 38.830 Hz.. and vsync is enabled by default causing it to run at this rate. Disabling vsync fixed it.

This is probably a thing on my side as I'm running on Wayland within gnome-shell.. so many layers.

Anyways since my inittial issue has been fixed, I'll be closing this for now and enjoy my Dreamcast games.

Thanks again!
