Thankfully I do not experience any kind of prolonged stuttering, but I have noticed it under certain graphically demanding circumstances, such as mid-spell casting with lots of enemies on screen + zoomed in. I too swapped to DX11 and I have more consistent performance with my RTX 2080 Super.
On Vulkan it would start off reasonably fine, but after about 30 mins to an hour worth of play, the frame rate would gradually dip. I can exacerbate the issue by adjusting the display options once I notice the FPS dropping, and then it drops more and more each time I change and save the settings. This is especially noticeable if I continually switch from Borderless to Fullscreen.
DX11 does not exhibit this problem.
