Thank you for playing. Most optimization issues should be caused by mist. What graphic settings you used?
In the boss fight there is wave attack. When Immerred says "For Justice" she activates red wave from Big Otomo. I failed to sync VFX and collision so mby you were hit by it. About stun animation there is one but you can cancel it if you spam block. It's a bug that I didn't fix.
That was a bug? I remember overusing that during the rooftop mobs lol.
I was playing with Low settings at 1080p the whole time (High was unplayable). It was actually running pretty good up until the last stretch before the boss. I think it was so many otomos and big crystals visible in a straight line. It affected the boss fight quite a bit too. It was still pretty playable, but definitely slower than the rest of the game up to that point. So I think just general instancing optimizations or LOD issue. No big deal really, my 'work' computer really isn't very strong for gaming.
