Preview 11 offers a change of pace. We took a step backwards, established some incredibly ambitious artistic and technical goals, and went heads-down for a few weeks. This release includes entirely new ocean, terrain, vegetation, and sky systems. We've also thrown in dozens of bugfixes, framerate optimizations, camera improvements, and a few other surprises. Please note that while you should see higher-than-ever framerates for all quality levels and platforms, this is the most technically demanding release to date and you may encounter the occasional graphical anomaly (especially in Freestyle). Also, the new GPU-accelerated cloud system is Windows-DX11-only at present.
