We are about 30 hours away from seeing patch 4.3 on HD+FE. A lot of wins in the performance department have been confirmed. Frame rate decoupled from network traffic and UI frame rate cost reduced dramatically. The UI frame rate didn't affect my PC but hurt the multiplayer experience because others with not as fast PC's caused the game to lag. Better performance for others means better for me They delayed release to brush up on other known issues. You will see best performance on windows 10 and that has been confirmed as well. It's safe to say they will have duplicate civs in all random fixed. That's what I know will be in the patch, I'll link the notes when it's officially released. Happy soon to be patch day HD fans.
