stuttering gameplay

You have to lower your Chunks settings in order to adjust to the new visuals in the game.

There's a lot more vegetation that gets loaded onto the screen which of course requires a lot more CPU work per chunk. so lowering this settings will lower the amount of work your CPU has to do.

When lowering your chunks settings, you may need to restart the game in order to apply the new settings ( just do it to be safe )

Hope that works out for you. if it didn't then drop down your PC specs it might help for troubleshooting this issue
