Exactly what has happened with my game, only I had stepped down from the HD textures for most things originally, though with this update, I have re-STEP-ed my game (especially as there seems to be a lot of updates to the overall project since I initially did it) in HD where applicable. It is downright beautiful. 60FPS, No lag, no skips, it plays like the STEP project no doubt has intended all along. Very happy with this.
