After seeing a lot of threads of "will my specs run beam?" I think it'd be a good idea to make the Bananbench a free standalone tool that would allow people to get an estimate of their performance so we don't need any more of these threads.
I worked on a similar project. The initial plan was to benchmark CPU with only the physics of the game. It would be a tools that allow us to optimize the physics depending on the average CPU profile. Sadly, it's a low priority project, we have no deadline dates.
