maybe this problem will be fixed with a new gui anyway, but in Renoise 3.1 under macOS 10.12.6 and a 4K screen, so Renoise displayed like 1920x1080, but scaled to fullscreen / 2x, the CPU amount on my i7 4770 (4 core / 8 virtual core, so maximum is 400%?) is around 50% !
If I reduce the framerate in the Renoise settings, the usage will drop. This is way too high CPU usage, should be around 5%?
FFT analyser: ~35%
pattern scrolling: ~15%
