So I made a few discovers on this, once I got done with the initial tutorial & went up to the moon, then made my hover craft & got away from the market area, it smoothed out pretty much, still doing some lag & stutter, but not so crazy like before. Then after I claimed my first location, harvested some items, it sent me back to the market location & again super laggy, stutter, ect... so obviously this is not a PC spec issue, but has to do with when you get into populated areas with other players and/or large constructions, ect...
