Hi,

Params::InterfaceGlRef impacts hugely on FPS on M1/Apple Silicon, it reduces greatly the frame rate.  
Here my environment:  
Cinder 0.9.2 / 0.9.3 - Xcode14 / macOS Monterey / M1

On Intel mac, it works fine.

Any helps to solve this issue?

Hi,

Sorry for the late reply while travelling - why not use the Dear ImGui that has shipped with cinder for the last couple versions? It’s quite easy to get going with, all the samples now use it rather than the older AntTweakBar (what `ci::params::InterfaceGl` wraps), the latter of which will likely disappear at some cleanup phase.

Cheers,  
Rich
