As promised, v0.8.0 focuses on tightening the nuts and bolts, bringing up everyone's FPS counters and smoothing out micropauses. I believe that keeping an eye on performance all the way through the development cycle is the only way to produce a robust title with solid framerates, and from time to time it's necessary to put some concerted time into optimisations. There's still work to do in this area, but this update puts us well on track once more.
There are both CPU and GPU optimisations in this update, with the CPU load falling up to 50% on some configurations. The GPU side makes better use of multiple threads and dynamic batching to bring down the load on your graphics card.
