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.

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..

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.

@Christoph-Hart Do you have any recommendations for working with OpenGL in regards to Fonts in OSX? My fonts degrade quite heavily with OpenGL but I really need it with this plugin.
