The sim was released atleast a year too early. The epilepsy filter also probably set them back another few months. They are apparently releasing a patch in a few weeks that spreads the workload somewhat more in multiple cores. They are also working on SLI/CF support.
Hopefully while people are working on the optimizations they have others working on the huge amount of bugs, and writing tutorials on engine management, etc.
The early release is a huge publicity debacle, but it was probably the only way to keep Maddox games from folding altogether. Now atleast they have funds to continue development, and with a little patience, the community will have a very substantial sim in time. I've already had at least 30 hours of entertainment, some of it frustrating, but the good hours were alot cheaper than any of my other forms of entertainment.
