HISE HEAVY ON GPU PROCESSING?

@Fortune It causes issues in certain contexts. For example, in Vienna Ensemble Pro it's a bit of a nightmare and my test users have had crashes whenever that setting was enabled. It can definitely speed up the interface if you have a massive number of knobs, sliders, waveforms. Waveforms are generally the biggest culprit in terms of GUI snappiness.

This is what Christoph said to me months ago about the OpenGL:
"Watch out for headless systems. I got a few bug reports from users that use PercX in a slave setup through Vienna Ensemble and their UI was black because they had no monitor attached to their slave PC so it deactivated any kind of hardware graphic rendering..."

Fortune

@Lunacy-Audio Very interesting info, thank you so much.

So maybe it is better to compile with open gl and without open gl separately, right?

Casey Kolb

@Fortune You can compile just once, but the OpenGL can be a setting in your Settings Floating Tile, so the user can choose which one to use.

Fortune

@Lunacy-Audio So first I need to set HISE_USE_OPENGL_FOR_PLUGIN=1 in extra definitions menu.

And also must use in Settings Floating Tile?

Also I can't see use open gl option in Custom Settings Floating Tile :/

Casey Kolb

I think you need to add a Settings Floating Tile and set the content data like this:

const var settingsEngineTile = Content.getComponent("settings_Engine_Tile");
const var isPlugin = Engine.isPlugin();
const var tileData = {
            "Type": "CustomSettings",
            "Driver": !isPlugin,
            "Device": !isPlugin,
            "Output": !isPlugin,
            "BufferSize": !isPlugin,
            "SampleRate": !isPlugin,
            "GlobalBPM": false,
            "StreamingMode": true,
            "DebugMode": false,
            "GraphicRendering": true,
            "ScaleFactor": true,
            "SustainCC": false,
            "ClearMidiCC": true,
            "SampleLocation": true,
            "ScaleFactorList": [
                0.5,
                0.75,
                1,
                1.25,
                1.5,
                2
            ]
        };

settingsEngineTile.setContentData(tileData);

graphicRendering is the OpenGL combobox that allows the user to toggle it on/off.

Oh I see Thank you.
So if I use this floating tile I won't need to use HISE_USE_OPENGL_FOR_PLUGIN=1 in extra definitions menu, right?
Also there is no combobox for Graphic Rendering even when I make it true.

Tania Ghosh

@DanH Ok....

HISE_USE_OPENGL_FOR_PLUGIN=1

Natan

@Tania-Ghosh Yeah, Just Paste That Code Into The White Boxes

Tania Ghosh

@Natan Superb (y)

DanH

@Lunacy-Audio Am I right i thinking "VoiceAmountMultiplier": true / false should also be in that list?!

"GraphicRendering" doesn't appear in my settings floating tile when I add HISE_USE_OPENGL_FOR_PLUGIN=1 in extra definitions menu. Is there something I need to do with Projucer to amek this available?

Natan

@dustbro Same Here @Lunacy-Audio

d.healey

@dustbro I think you need to add it to your custom settings floating tile as Fortune showed in his image a few posts back.

"GraphicRendering": true

Dan Korneff

@d-healey i tried. Not showing up ‍️‍️

Fortune

@d-healey Same here like @dustbro & @Natan "GraphicRendering": true doesn't make the opengl combobox show up in CusotomSettings floating tile.

I am also confused that, in order to make OpenGl enable:

Is HISE_USE_OPENGL_FOR_PLUGIN=1 enough?
Or should I do HISE_USE_OPENGL_FOR_PLUGIN=1 and "GraphicRendering": true both?

Natan

@Fortune It's Enough Here.
HISE_USE_OPENGL_FOR_PLUGIN=1

And No Extra Codes

DanH

@d-healey FYI everyone, it seems my FloatingTile "FilterDisplay"s were causing a lot the GPU lag.

d.healey

@DanH How many did you have displayed at one time?

DanH

@d-healey 6..... And then a spectral analyser, 4 audio waveforms, a Goniometer, 2 tables, a sliderpack, and 3 sliders linked to LFO gains which would be constantly moving... lol

But actually way back in the beginning of this project I noticed the lag (before all the extra stuff), and I never considered the Filterdisplays to be the issue, and removing them has made the biggest difference of all.

DanH

@Fortune Ok so.... I was thinking the same thing and I just compiled my plugin and opened my 'settings' tab and there is the 'Use OpenGL' option! Weird!
