HISE HEAVY ON GPU PROCESSING?

[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!

[DanH]

@DanH And I would also like to point out that selecting the 'yes' option here has completely sorted out any GPU lag, even on my 9 year old laptop! Bravo @Lunacy-Audio

[DanH]

@DanH it's never quite that straightforward is it.... Selecting yes here means that the font in the button below now goes weird! lol

[DanH]

@Natan So it does't seem like the code "HISE_USE_OPENGL_FOR_PLUGIN=1" actually does anything to my plugin..

FloatingTile "FilterDisplay"s were causing a lot the GPU lag.

I have a project with 3 filter displays and it's practically unusable on certain computers. It make the entire DAW GUI lag.

Bummer! I was hoping that was the magic cure

[DanH]

@dustbro Well the OpenGL setting is definitely going to help this. We need to figure out how to set it 'on' via scripting now! @Christoph-Hart any ideas Christoph?

@dustbro @Fortune @d-healey @Natan @Tania-Ghosh Ok so I found this thread:

Open GL

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

Forum (forum.hise.audio)

@Lunacy-Audio found the setting in this doc: StandalonePopupComponents.cpp – line 128

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

I've set it to 'true' and recompiled HISE and now I have the 'Use OpenGL' option in my CustomSettings window :)

[DanH]

@dustbro Are you Mac or PC? Changing the OpenGL setting has made a huge difference on Mac, but the reverse is true on PC!

[Dan Korneff]

@DanH said in HISE HEAVY ON GPU PROCESSING?:

Are you Mac or PC?

Both

[DanH]

@dustbro did you test it on both? What was your outcome? I'm now finding on Mac that the the general resolution is not as high when OpenGL is on, knobs and texts look more blocky.... :(

[Dan Korneff]

@DanH said in HISE HEAVY ON GPU PROCESSING?:

did you test it on both?

Not yet. I'm gonna test out a version with the FilterDisplay disabled first, then trying OpenGL. I'll post an update when I have some info.

[DanH]

@dustbro Cool, so FYI it seems you'll need the 'HISE_USE_OPENGL_FOR_PLUGIN=1' definition as well as the '"GraphicRendering": true' solution noted in the thread above in order to test the OpenGL stuff...

I had just removed it and, whilst the UseOpenGL box was still in the settings window, it didn't change anything.

I'm not seeing any quality issues due to OpenGL on mac or pc. I DO, however, have an unrelated image quality issue I need to figure out.

Definitely seeing a benefit on Mac. Testing PC now.

@DanH @dustbro Not sure if this helps, but you can also manually toggle it in your product's General Settings:

<?xml version="1.0" encoding="UTF-8"?>

<GLOBAL_SETTINGS DISK_MODE="0" SCALE_FACTOR="1.0" VOICE_AMOUNT_MULTIPLIER="2"
                 GLOBAL_BPM="-1.0" MIDI_CHANNELS="1" SAMPLES_FOUND="1" OPEN_GL="0"/>

I think so. It doesn't solve the mysterious crash problem on startup but definately speeds up.

Samplitude Shows Blank Screen When The OpenGL Is Enabled :(
@Lunacy-Audio The Setting For Disabling OpenGL won't Show Up At My End, You Have Any Advice?

@Lunacy-Audio said in HISE HEAVY ON GPU PROCESSING?:

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.
