[2021] Stutters got worse, game unplayable on Vulkan

A while ago, with the introduction of the previous season or one of the patches afterwards, I've noticed that in t-hunt the game would stutter more. By stutter I mean momentary pauses. Usually when the enemy appeared on the screen. The hardware didn't change (AMD CPU&GPU), Windows didn't change (Windows 7, Vulkan), it was after one of the game updates.

After today's patch, the stutter got even worse, to the point that t-hunt became unplayable. I mean it can be played, the same way as people can climb Mount Everest, it's just not very enjoyable. I'm outside, running straight ahead, nobody in sight, game still stutters every few seconds.

I've recorded this to demonstrate. I run RTSS which displays frame rate chart top left. Normally I get steady 144 FPS, with OBS bit less. The stutter is visible as spikes on the chart. Here's the video:

Unfortunately, this extends to multiplayer too. Same exact thing.

I would kindly ask you, Ubisoft developers, to fix this and not f*ck up the game like this further, if at all possible. Thank you.

Tried DirectX version now, it's mostly stutter-free, so it's a thing with the Vulkan version.
