Tried it on Windows on a powerful workstation. Felt sluggish. The framerate seems to be capped as 60Hz. My monitor is running at 240Hz. Removing the framerate

Tried it on Windows on a powerful workstation. Felt sluggish. The framerate seems to be capped as 60Hz. My monitor is running at 240Hz. Removing the framerate limit could help.

It's actually not even 60. The FPS target is configurable in the settings and for some reason the default is 57.

Does it bother you when you see flourescent lighting that's connected to 50/60 Hz mains power and you just see violent flashing? (edit: This isn't snark, I can't see changes that fast, but I know what they look like slowed down and that other people may be different to me.)

  Not the OP, but yeah that used to bother me when I was younger. As did any CRTs running below 75hz My “super power” used to be that I could tell what refresh rate a VDU was operating at just by looking at it. Well, I couldn’t tell past 80hz. But anything below that I could.

  Most lights try to avoid flicker in the design, but bad/failing ones can drive one nuts. E.g. fluorescents flicker at 120 Hz (2 crossings per cycle) but the phosphor coating carries some glow and that they stay on for ~80% of the cycle time anyways makes it a lot more bearable that if it were an idealized instantaneous 50% duty at a 60 Hz rate. God bless LEDs with some capacitance though...

  Fifteen years ago I started to develop mild neurological symptoms. Mostly headaches, some minor muscle twitches, and some weird vision issues. I started working with first my GP and then with a neurologist to try to get to the bottom of it. The investigation was leading towards some form of optic neuropathy. In parallel I moved to a new job. All of my symptoms went away and in retrospect at the time all of the symptoms had started when I'd started that job. The fluorescent lighting near my desk there was terrible and as far as my doctors and I could figure out that was likely the cause of it.

This is the exact opposite of what I want, actually: imgui keeps promising an official mode that doesn't totally melt the machine from running at peak refresh rate the entire time (since it was developed for games, not normal desktop apps), but it never materialises, and the hacks we all implement ourselves stop working as they update the code etc. Everyone seems to want 9234567345863489634589 fps, when that's IMO completely absurd for a normal desktop app, e.g. editor! What you actually want is low latency, not constant massive bandwidth and power usage. If all your normal desktop apps constantly ran at uncapped FPS, your computer would scream and laptops wouldn't last 5 minutes on battery.

  It should be running at 0 fps, then when there is movement it should run at refresh rate.

    It blows my mind how controversial this obvious point is; makes me wonder if people also keep their washing machines running at full tilt without any clothes in them.

  Wouldn't it look stuttery if the user tried to drag windows or other widgets with a limited framerate? > What you actually want is low latency High frame rates directly contribute to lowering latency. I guess I'm the polar opposite of you here, I heavily prefer low latency/high refresh rates over low CPU/GPU usage, as long as the machine is plugged in to a power source.

    Maybe it's car analogy time: this is a bit like saying, well it's fine if my car is redlining 24/7, as long as it gets the speed I want when I happen to be on the highway. Nobody is saying they want to tolerate some horribly laggy interface for the sake of lower CPU usage. The point is simply about not wasting enormous amounts of power when it's not needed.

To all other comments in this thread. So many "hackers" apparently did not hear about adaptive refresh. There is no need to update a static image every 240fps. You only need to increase the refresh rate for animations like scrolling, like in... everywhere??? Android, macOS, Chromium, Qt, and GTK(?) do this.

Hey Ned developer here, there is a target fps slider in settings. I am able to get 800+fps on my MacBook m4. There is a mode where it reduces fps until user input on Mac to save battery life. However this only works with shaders turned off, as the shaders depend on continuous rendering.
