Lag in Develop...

[Dan Korneff]

I haven't seen it here on any platform using all of the latest develop commits. Currently not using IPP.

@lindon Are you not asking too much processing in a timer, paintRoutine, LAF function, etc... ?
A while ago I experienced UI lag because I had too much component on the interface (several hundreds I reckon because of a big mod matrix)

[Lindon]

Is this with a fresh project?

nope - just projects initially built with Master - which now compile and run in Develop....I heven't spent enough time in Develop to build and complete anything from scratch.

[d.healey]

@lindon Then it could be something in your project which was tolerated by the Master branch but the Develop branch isn't so keen on.

Well I don't think it's "too many widgets" - as this has not been a problem in Master, and as it happens I'm running two timers only - 1 to do VU meters and one(when they are asked for) in the presets - but now in develop I'm using the pre and post preset load callbacks so - I'm actually using less timers than in Master.

Opening the preset browser and loading up some sub-categories (about 15 of them) is taking a very long time to do in Develop

Cant say I'm seeing the same results on Mac....

@lindon Running HISE Debug Build I notice JUCE Assertion failure in PresetHandler.cpp:2629 before I've even opened my project. Might be related.

right... this fix is down to @Christoph-Hart right?

[d.healey]

@lindon I've just taken a look at the assertion in the source jassert(f.exists() && f.isDirectory()); It doesn't look like it should be causing a lag issue, so I guess this is unrelated to your problem after all.

[Lindon]

@d-healey - well in any case its not just the presets browser that is behaving badly - its widgets all over the place... I think its a bigger problem.

I cant get the develop branch to behave well under windows at all...

[d.healey]

@lindon Can you make a minimal example?

[Lindon]

@d-healey said in Lag in Develop...:

@lindon Can you make a minimal example?

minimal? no. I think this is about scalability...

[Lindon]

@lindon - so more experimentation - the preset problem is to do with the number of presets in a sub-category - 10 or 12 no problem, 30-100 presets? - big problems....as soon as the number of presets is bigger than the page there are problems.

[d.healey]

@lindon Is this with the stock preset browser?

[Lindon]

@d-healey - yes....

I just made a "minimal project" - no back end no sound nothing only widgets

30 sliders, 15 buttons and 15 combo boxes... Button 1 turns on/off a panel holding a stock preset browser.... as soon as I create more presets than fit in a single screen I get really really bad lag.

I copied and pasted the same preset 30 times and its nearly unusable...

@lindon in the exported plugin or in HISE?

[Lindon]

@danh in HISE.. though my Beta testers are reporting the same issue with the compiled plugins.

Is the lag present in the scrolling of the preset browser list?

[Lindon]

@d-healey - yes thats what Im saying - create 30 presets in a single sub-folder - open the prest browser - go to the sub-folder - and try and scroll through the list of 30 presets.

[d.healey]

@lindon I created 120 presets and no lag here, but I haven't tested on Windows yet. I'll do that now

[Lindon]

@d-healey -I have no lag on MacOS either its WINDOWS problem (I think)
