Opt-out of G-SYNC

[parasyte]

G-SYNC is a huge pain for windowed apps with differing refresh rates. When running CarTunes on a system with "Windowed G-SYNC" enabled, some apps like Edge will start to stutter (especially when playing videos). Switching focus between CarTunes and the other app will change which app stutters.

There is a way to opt-out of G-SYNC using the Nvidia control panel:

But it's kind of painful, and very hidden.

Windows Terminal used to have this same problem. But more recent builds show "Not supported for the application" in the Nvidia control panel. Suspicions in that thread indicate that Nvidia has "blacklisted" Windows Terminal so it doesn't enable G-SYNC. But who knows, honestly...

Ok, this can be done with NVAPI: https://gist.github.com/rickbrew/10e5c0fa3593ceb6f03766914f43a0c6

There is a Rust crate for it, but it doesn't have any of the DRS stuff.
