Vermintide 2: Frametime Spikes

I've been playing Vermintide 2 lately (Ryzen 5 5600x and RX6800XT). In general, the game looks and run fine. But, I get occasional frametime (one word or two?) spikes. According to Adrenalin, the game's 95th percentile for frame time is 16ms (with framerate pretty much staying where I fixed it at about 60 fps (actual average is 55.6 fps). But, every minute or so, I'll get a spike off to about 85ms. If anyone else is playing the game, do you see the same thing? Is it the game? Is it the GPU/CPU? Or, does the game just not like AMD?

It looks like my using DX12 in the game was the problem. I switched to DX11 and the frametime spikes went away: 55.8 fps and 16ms frame time. Odd since I'd read some comments here and there on this board that there is some kind of DX11 issue on AMD.
