Update:
Tested DXVK on windows, no stutter while "Compiling shaders..." during game play.
Frametimes are similar to native dx11 but moderately more gpu usage (33% vs 50%).
I mean yeah, Nvidia's Vulkan shader compiler is slow and the game compiles everything at draw time. Can't really do anything here.
After I moved the game from ntfs to btrfs. i couldn't reproduce the issue even after clearing nv cache.
Not sure what ntfs has to do with shader stutter, my prefix where shaders gets stored lives in btrfs.
I think this can be closed? Notably DXVK doesn't stutter in windows.
Eh, well, fair I guess, but these Frostbite games are somewhat known to have stutter problems anyway if stuff isn't cached.

Issue
Battlfield 3 has severe stuttering that happens in time with "Compiling shaders..." indicator.
On windows (native without dxvk) the issue doesn't happen, not a single stutter.
Haven't tested older DXVKs
