Open GL

I‘ve added it as runtime option in the settings menu so there‘s no need to build two versions.

@Christoph-Hart Oh even better! :)

Very cool ;) However, since Apple has deprecated OpenGL (from Mojave), maybe in the future the Metal support would be good too ;)

I don't see it in the setting panel, is that normal? (macOS)

I'm also trying to render the entire plugin as OpenGL. Is this still an option in the settings? I'm not seeing it in any of the recent builds.

[Casey Kolb]

Oh, I think I found it in StandalonePopupComponents.cpp – line 128

#if !HISE_USE_OPENGL_FOR_PLUGIN
	properties[(int)Properties::UseOpenGL] = false;
#endif

[arminh]

I still have issue where on Windows everything is smooth but on Mac is really laggy :(

[Casey Kolb]

Hmm, it sped up my Mac plugin by like 200%. Crazy difference in speed.

[ustk]

So is it a pre-processor command finally?

[Casey Kolb]

I just set the flags in HISE before exporting

HISE_USE_OPENGL_FOR_PLUGIN=1

[ustk]

@Lunacy-Audio Ok thanks! I never think about the possibility to set flags in the preferences…

[Casey Kolb]

Yeah, same! I've had to do some digging for a few of them.

Isnt OpenGL depreciated on the latest Macs?

[Casey Kolb]

It's officially "deprecated" by Apple, but it's going to be around for a long, long while. The plugin I'm working on is using OpenGL almost exclusively for the main component and works across all Macs without any issues. With Windows it gets a little fishy because the graphics cards are all over the place, but in general also works fine.

yes this is my understanding too, however it's not so simple - the latest MacOS (and I assume all future ones) will use rosetta to virtualise your code - so you may see some performance hits as it morphs your OpenGL calls into Metal calls..

[Christoph Hart]

Doesn‘t rosetta just turn intel binaries into ARM ones?

oh maybe it does - how do the OpenGL calls get managed then on machine that only has Metal?

Is that possible without recompiling from source?

[Christoph Hart]

Yes, it converts the x86 assembly of a compiled binary to ARM assembly and then uses some kind of emulation layer. It works surprisingly well but you get a little bit of CPU overhead compared to a natively compiled binary for ARM.
