What sort of performance increase is generally seen from enabling SIMD? Obviously I know it will vary from project to project, but what sort of range are we talking about? 5%? 10%? 50%? 100% (in terms of processor time to solve the step)?
I'm currently using the evaluation version to develop a game, but it is fairly physics heavy. If SIMD is a fairly noticeable increase in performance, then I guess it would be worth my while inquiring about the Budget-based License sooner rather than later.
Edit: I had read outdated information that SIMD wasn't avaliable for the free downloads, but I can see it listed, so I'm just going to try it.
