Making Your Game Go Fast by Asking Windows Nicely

Two comments that kinda go against the flow:

1. Please add options to conserve battery too. A FPS limiter would be good. Messing with the system power management when the user doesn't want to be tethered to a wall plug is Not Nice(tm).

2. When you do UI scaling, especially if you're young with 20/20 eyesight, please allow scaling beyond what you think is big enough.

The other reply mentioned that vsync can save battery--on top of vsync, Way of Rhea supports syncing to every other vblank, halving the FPS. This will presumably should save even more battery (though the intended use case is to prevent stuttering on computers that can't consistently hit the monitor's refresh rate.) Ultimately, though, no matter what I do I don't think you're gonna be able to play very long on battery power.

For #2--my glasses prescription is so strong that I spent $330 on fancy lenses today in the hopes that they'll distort less around the edges. Wish me luck. (:

1. FPS limit needs to be an integer multiple of the display refresh rate, or you introduce stuttering. That’s why missing a vsync results in exactly 30fps on a 60hz monitor, and that isn’t a good user experience.

Using Vsync is actually conservative power wise. You can always smash the gpu by rendering frames as fast as possible. This a one way of reducing input latency in FPS shooters, using vsync guarantees one frame of latency on a fast GPU.

2. Agreed 100%. All too frequently the UI is too small on high dpi monitors (see CIV6), or unreadable when viewed from a distance when playing on a TV (see Witcher 3)

It depends on the game. What does Civ need 60 fps for? Not sure if they have a limiter because I'm not playing 6 due to some of their design decisions that tick me off.

On the other hand, I do keep my Minecraft limited to 30 fps.
