> This is not hacky or has higher power draw - the display has a minimum refresh rate, and sudden large changes in refresh rate can lead to visible flickering. I get that[1]. It's a shame we can't specify next frame latency as well, it should be fairly predictable for video (or enable triple-buffering on the monitor side). > It is negligible. Your GPU will do nothing most frames, and the panel power consumption comes from backlight. I was basing this on a recent patchset with the following quote[2]: > Enabling this feature also have the potential side effect of causing higher power consumption due to running a mode with lower resolution and base clock frequency with the highest base clock supported on the monitor as per its advertised modes [1]: https://github.com/swaywm/wlroots/issues/1406#issuecomment-473465765 https://github.com/swaywm/wlroots/issues/1406#issuecomment-4...
