Hard fps lock to refresh rate value in fullscreen games - Win11 22H2 (DX11) about directxtk

Compat issues are best addressed to the original developer/publisher, but you can also file an issue with the Feedabck Hub.

Note that all DirectX 12 applications use a newer style of flip and have "Full Screen Optimizations" in place. This means they are not actually using old-school Full Screen Exclusive. This is referred to as "emulated Full Screen Exclusive" (eFSE). This is on for DirectX 9 application as well, but it only enabled on a case-by-case basis with DX11. It's quite possible that there's some bug in the game that requires a fix from the developer to properly enable the modern flip swapchain mode and the codepaths related to "variable refresh rate displays".
