Found the issue testing locally

[im-knots]

created #43
tested fix with arch -x86_64 /Applications/Varda.app/Contents/MacOS/varda since i dont have an actual intel mac.
seems to start up for me now. sorry about that! Will merge the above pr and cut a new release pronto

[im-knots]

@FreQRiDeR try out https://github.com/im-knots/varda/releases/tag/v0.1.4
It should now launch. Let me know if you experience other issues and thanks for the detailed bug report!

[FreQRiDeR]

I ran from source with your changes and it's fixed! I also just tried the new binary and it also works fine! However, I'm getting 3-5 FPS on my system. LOL With only 2-4 Chanels and 2-3 effects. Strange because I run TouchDesigner, Resolume with 8 sources and multiple effects with acceptable FPS.

I love the simplicity, layout of Varda. This is how I prefer vj apps to be laid out. I came from Modul8 so 4 channels A and B with a crossfader. It's exactly how I set up TouchDesigner as well. Great because you can run your four layer composition on A while working on a composition on B. Shame it won't run acceptably on my macPro 3,1. (8core 3.2 ghz Xeon cpus, 56 gb ram, RX580 gpu) I'm sure it works great on Apple Silicon!

I am very much actively chasing performance gains across the stack. i have been primarily chasing down engine optimizations so far in varda itself. However all the generator and effect shaders bundled with varda are also from scratch so i know for a fact some of them are horribly optimized. if you have known performant ISF shaders in your library throw them in .varda/shaders and try those out to see if they are more performant than the bundled ones :)

Varda is deff in a very early alpha state right now. stay tuned for performance gainz as me and @DanceMore chase them!

[reset131]

Same here, I'm getting 3-5 FPS on my 2015 MBP.

[im-knots]

reopening this issue since both of you are having the same problem and reporting it in the same place (very helpful!)

@FreQRiDeR what version of macos are you on? you running metal or opengl backend?

@reset131 whats your system specs and os version?

for both of you, can you please post your .varda/scene.json files so i know what you are working with in the software?

lastly a general usage tip: varda isnt like other vj software where its a clip grid. varda more like a broadcast mixer, you have to use opacity, mute/solo, ect to cull stuff from the render loop as part of your workflow. its a bit of a mental model change. but it does help performance a lot if you only have your actual current outputting channels and your cue channels hot at any given time with the rest culled.

Im going to be digging into this today. im already chasing some hot paths that i think would make it extra sucky on older hardware
@DanceMore this may help you too
