I've noticed that after the last Experimental update on my Steam Deck, AC Valhalla can no longer maintain smooth 40 FPS in most scenes. Out of curiosity, I've tried VKD3D_CONFIG=swapchain_legacy and with that frame times were back to normal.

Legacy swapchain:

20221204212207_1

New swapchain:

20221204213535_1

Interestingly, when I press Steam + R1 to make a screenshot, it goes back to smooth 40FPS, but only for as long as the "screenshot saved" notification is being displayed.
