GPU Audio [new technology or not new]

If I were making a DAW, I think I’d want to build it on top of something like Cairo, Skia, or ANGLE. The popular web browsers take this approach.

I would love to see this. Especially considering that the current CPU-rendered GUI is having major performance problems on HiDPI displays:

Slow framerate with HiDPI in fullscreen mode (on a Mac Book Pro 2018)

I’m having the same problem. The issue seems to be with the surface area Renoise has to render to: The bigger, the worse the performance. I get the same poor performance in a maximized window as I get if it is full-screen. I don’t know how Renoise’s UI is rendered, but if it is not using the GPU, that may be the source of the problems as rendering on a 5K display as the iMac 27" I have with a CPU is going to be extremely costly. And it’s not like my iMac is a slouch: [image] What’s weird, tho…
