World rendering is way too slow & broken

I'm still waiting for the Switch version to not have a huge portion of the world not rendered in for a very long time. Any Short or Lengthy travel by foot, boat, or horse, etc; on the Nintendo Switch edition of Bedrock will greatly stall the world render speed. It isn't playable at the moment. I'm tired of standing still most the time, waiting for the world to finish loading, while both attacking mobs & most the world itself  haven't been shown to render in. This Version needs to be better optimized, soon. The blocks that do show to be rendered, sometimes appear to be missing multiple sides. Please fix.  Perhaps an "up to 30fps lock" is needed; only if it helps...which would be unfortunate, but it may be better than constantly not being able to see a huge portion of the world and/or look through it
