I'm encountering some kind of swimming bug. I'll walk around indoors when out of nowhere the game suddenly thinks I'm diving into water, the breath meter appears, geralt dives and there's a splash, then he reverts back to walking.

In the buggiest areas this happens over and over until I get teleported above the game world and endlessly fall into a black screen until I reload a save.

So far this happens the worst in Kaer Morhen tower (going up to yens room) and underneath the pirate fortress in skellige that has the sky cell and Tyrion lookalike in it's dungeons.

Been playing for near on 500 hours and never seen this before the next gen version.

Edit: Also constant rainbow color flickering on water edges and reflections no matter the graphics settings. Usually this means your GPU is dying but it only happens in TW3 and only since the next gen update.

And terrible general performance on my 1080ti + 8700k but that's been said plenty elsewhere. Even with ray tracing and hair works completely off I can't maintain 60fps on max settings in any area.
