After playing the various Opt-in versions and the release version, I have noticed that the ship movement is very jerky and no longer smooth. My system has run the game maxed out without issues (for the most part) since the Alpha but this is some of the shakiest movement I've seen to date. Drivers are up to date with the latest official release versions. Specs as follows:
Maximus VII Hero, i7 4790k @4.4GHz, EVGA GTX970HD 355.82s, 32gb DDR3 2134, 1000W PS, Onboard sound, 32" Bravia XBR, Win7Pro64
Even after a fresh reboot and making sure no other unnecessary processes are running I get this kind of graphic oddity. Current game is on an Insane map, 50 major races, rare minors, tight clusters, common stars, abundant planets, Gifted AI, and the rest at default except only doing a conquest victory.
