How to reduce Windows 11 input latency?


The compositor in Windows has V-sync turned on, surely this creates input. Any way to disable it?

No there isn't and no you don't actually want to do that unless you want to get windows that slice in half as you drag them around and other very nasty and ugly visual anomalies.

You have to remember that what you see visually isn't the bottleneck. You can type as soon as a window can accept input. Any visual "input lag" isn't actual lag to input. Disable animations and transitions and you get a very snappy OS.

Also think of it this way. If you have a 120hz or 144hz or higher monitor... You have a vsync locked desktop at that refresh rate... It's very much not input lagged.

The feeling of editing code and doing art in Photoshop on my 1080p 120hz lightboost ulmb monitor feels amazing. When I turn it down to 60hz it feels like molasses. At 144hz it feels good but then I get slight ghosting due to no backlight strobing.
