HISE HEAVY ON GPU PROCESSING?

d.healey

I haven't noticed any issues, does your plugin have a lot of interface components?

DanH

@d-healey about 60 knobs on the main interface, plus 6 analysers (which you can toggle on / off - def helps performance with them off but not game changing). It's busy for sure. Knobs are made in Knobman and about 0.5MB in size. It's a lot slower if I use images so have mainly used paint routines. I don't notice much on my new mac mini, but on my 2013 mac air it's very noticeable.

I also have a project with 100 instances of my plugin and the graphics really freeze up in it lol

@DanH Danny, Use The OpenGL Option, It Smooths The Performance Out
Just Add This Line, Into The Prefrenceses, For Win, Mac, And Linux.

Works Like A Charm Here

HISE_USE_OPENGL_FOR_PLUGIN=1

DanH

@Natan oh great, will try asap thank you!

I didn't find it in preference >settings... Can you guide me where it is located exactly?

DanH

@Tania-Ghosh You have to enter it into the 'Extra Definitions' boxes in Settings.

It hasn't made a huge difference for me, will continue testing though

@DanH Be wary of the OpenGL option. It's a naughty little beast and will screw up a lot of things if you're not careful. It's better to optimize your GUI first by removing unnecessary hover and drag callbacks from panels, etc.

Try optimizing the code as well: https://forum.hise.audio/topic/79/scripting-best-practices/2

DanH

@Lunacy-Audio Will do, cheers!

So is it possible that enabling open gl can cause issues? What have you experienced so far? Can you please give an example or a little bit info about it please?

Casey Kolb

@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.

                1,
                1.25,
                1.5,
                2
            ]
        };

settingsEngineTile.setContentData(tileData);

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?
