* Multithreaded image loading, each thread can load a separate image. * Better multithreading for multiple instanced meshes, different threads can now build BVH's for different meshes, rather than all cooperating on the same mesh. Especially noticeable for dynamic BVH building for the viewport, gave about 2x faster build on 8 core in fairly complex scene with many objects. * The main thread waiting for worker threads can now also work itself, so (num_cores + 1) threads will be working, this supposedly gives better performance on some operating systems, but did not measure performance for this very detailed yet.
