Description
Description
With Vulkan driver, the menu refresh rate is capped to 60Hz even if ‘Throttle Menu Framerate’ is disabled. Switching to D3D11 or GLCore correctly adjusts the menu refresh rate to match the screen frequency (120Hz in my case).
Additionally, with Vulkan, there is a slight stutter/delay when activating fast forward (and when stopping it). This is particularly noticeable when using a resource-intensive shader. This issue is not present when using D3D11 or GLCore.

Research direction
Start by reproducing the menu refresh-rate and fast-forward transition behavior with Vulkan, then compare it with D3D11 and GLCore using the stated Windows 11, RTX 3070, and 120Hz setup. Done means Vulkan matches the display refresh rate when throttling is disabled and fast-forward activation and stopping no longer stutter, including with a resource-intensive shader.
