The new assets are looking real nice, it's really coming together. I particularly like the new pistol and plasmagun.
I ran into a few issues but Cybdev already covered most of them, I would just say the near-clip is a bit far off so I can see through walls on an angle if right next to them. My FoV is set to about 75% so it might not be visible lower.
Had to play the GL version on Linux due to libvulkan.so.1 missing, but I've made no attempt to explicitly check if Vulkan is even set up to be working on my end.
The mouselook slowdown seems to be related to animated actors being in the view frustum (whether they're visible or not) and can be seen especially on the second level after dropping down the red pipe. Panning around standing in front of the red door causes much lower mouse sensitivity when the rocket-launcher area on the opposite wall is visible. Funnily enough, I get the exact same problem in Jedi Outcast and Jedi Academy when running via Wine/Proton.
You could also use some sort of V-Sync or frame limiting as the game constantly squeezes its core to maximum.
