DirectX 11 vs Vulkan: which is best for Baldur's Gate 3? - Beehaw

I think this will vary too much between OS and hardware. For me, Vulkan feels better overall. Dx11 looks slightly better but less performant.

But I’m running all and hardware, Linux steam with proton.

I'm on linux with hyprland. With vulkan i get large black boxes that flicker in the bottom third off the screen.
That’s weird, I do get the black boxes as well, but a much smaller portion of my screen. What resolution are you running? I’m at 4K.
1440 (whatever is between 1080 and 4k)
