Broken frame limiter on Asus ROG Ally after 3.0.0 update

[Stas]

Describe the bug

After a successful update to 3.0.0, the built-in frame limiter stopped working. Before the update it worked as expected.

What I tried:

• clean install, same result.
• deactivate "unified frame limit management" in the Developer Settings, same result.

For now, I'm using DXVK_FRAME_LIMIT in game launch options (mangohud limiter works too), but it's not convenient.

What did you expect to happen?

Working built-in frame limiter.

Same bug on Legion Go with fresh 3.0.0 install, but DXVK_FRAME_LIMIT has no effect either

Seems to also be the case on the Win Max 2 (6800U).

It seems to me, that it only works if the game is vsync'ed. Without vsync framerate is not limited.
