Game stutters (visually) when a block is placed (or broken). Seems to be correlated to how long the world has been loaded for, as it wasn't noticeable when first starting to play in world.
Persists through exiting local world and reopening, but exiting and reloading game client appears to fix/lessen.
Have the same issue with 16 Core 4Ghz processor and gtx 1080Ti.
