This has been a source of major butt hurt for a large number of users. We're a day or so away from releasing a fix that will solve (let me make a number up and say) roughly 80% of the pain for 80% of users. The other 20% is still a long ways off, I'm afraid -- at least another two weeks. We will get there, though, and we know how to get there it's just a lot of work. No comment on GPU acceleration
