f.lux works by simply setting a new ICC profile - right? That’s often supported directly in hardware in the GPU’s scanout system (so it doesn’t appear in your framebuffer). So why would that cause poor performance?
yea never had any performance related problems on the visual end of things with flux (typing this with it on). Although flux is getting pretty outdated on Big Sur, so there are some hiccups and lockup bugs that could be interpreted as "performance issues".
