Homebrew Discussion OPENGL finally on horizon SWITCH??

[Deleted User]

Does this mean better emulators?

Yes. Software rendering in emulation sucks most of the time, so GPU usage for graphics instead of CPU will make performance an order of magnitude better (and save the trouble of writing/porting a software renderer in the first place).

 

[steven89]

it mean in simple term slow and steady progress in the graphics department it not ready just yet, completely up to devs how they implement in there homebrew though, for some a lot homebrew like retronx it would require major rewriting of the code base @m4xw said this, however once complete more homebrew could be make with this code in mind and there for bring a wide variety of different projects to the table

Does this mean better emulators?

At the very least some of the emulators currently out of reach due to performance limitations of software rendering will now be fair game. Plus a ton of other games which rely on OpenGL will be much easier to port so they'll be a bunch of those pouring in. Anything relying on SDL can have one line of code changed during the init phase and should see a nice speed boost (though for things with delicate timing and hacky workarounds, some stuff will have to be rewritten a.k.a. half my stuff)

Shaders and filters on 16/32-bit emulators? Really?!

"After a long debugging process, way too many mesa recompiles, and Armada's wonderful assistance, I'm happy to say that OpenGL 4.3 (Core Profile) can be used now.

If all goes well there will be a public beta test release within a week, stay tuned for the ( ͡° ͜ʖ ͡°)s!"

While this is excellent news (and it really is) why is the focus on OGL instead of Vulkan?

AFAIK, that would involve more work.

That's an understatement.

 

[OkazakiTheOtaku]

Which will come first?
Aux/Speaker sound on Lakka, or fully implemented 3D acceleration on Horizon Retroarch?

Step right up and make your bets, ladies and gents!

 

[mrsupertom]

As per @natinusala & @fincsdev on twitter...

It's happening folks! OpenGL PSX and beyond, here we come

Major creds to fincs & armada for this, and the RetroNX / Lakka team!

 

[daxtsu]

(and the dev who started the work, i forget their name)

Armada. But yeah, it's really exciting, especially once SDL2 also gets hooked up to this OpenGL implementation, then a ton of things can be easily ported.

 

[mrsupertom]

Thanks for clearing that up (us naive non-techies eh? )

The missing puzzle is JIT, not GPU.
Actually opengl will do nothing to pcsx (unless u want more bugs/glitches!)

 

[daxtsu]

Thanks for clearing that up (us naive non-techies eh? )

M4xw is correct, PS1 isn't so heavily reliant on 3D acceleration, OGL would mainly just look nicer. JIT would do a heck of a lot more for that use case. But N64, PSP, and beyond benefit from both greatly.

From @finccs tweet:
It's based on mesa and nouveau, which only implements GL. Vulkan support is something nouveau doesn't have yet, but the team behind it is working hard on it (also it wouldn't really be part of mesa if I understand correctly).

Nouveau's team plans to add vulkan support by the end of the year I think?

 

[Brunz514]

Hopefully we can get proper n64 and gamecube emulation in retro nx now! I need some proper smash bros on my switch before december!

Yes, that was the original plan, but not much news... The post below is from February...

Apart from JIT and Vulkan this is the news we've been waiting for so long.
No matter how long it takes, I'll be very happy if I can play through Super Mario 64 in Horizon in full speed.

 

[mustafag32g]

so we can get moonlight soon? damn this is exciting

Sweeeeeeet, hoping GC support comes with better than current speeds now! Hype!

Several clarifications: -
Based on Armada's mesa port, continuing where he left off
- This is OpenGL, and concretely es2gears
- Still a lot of work to do but at least this basic program runs at 60fps w/o glitches
- libnx gfx code was overhauled - hopefully no more dequeue fatals!

Feel free to correct me

So sweet whuhuuu
