Using ANY part of ReShade in Doom Eternal (Vulkan) always causes a 10 FPS drop

Like the title says. Even using just the FPS counter without ANY ReShade effects enabled always drops the fps by 10.

And if you have absolutely nothing from ReShade on, just opening the ReShade customization window causes a 10 fps drop.

Seems to happen when any aspect of ReShade is displaying on the screen.

Using 4.6.1, the Steam version of Doom Eternal, and all my drivers are up to date if that matters.

Mainly tested in the main menu with the slayer on the podium, happens in levels too.

EDIT: Tried (one at a time) disabling all my overlays (like Nvidia, MSI Afterburner), Turning on and off Windows 10 Game Mode, Enabling and Disabling Fullscreen Optimizations, Running as Admin, using Windowed and Borderless Windowed Modes. None helped.
