I would have to see how you’re doing things before I could comment on any improvements. Since you mentioned the PMC, what issues are you having with it? I kind of watch what people are doing with it as well as my improved version to see what areas I can further improve. I’m currently working on some of the collision support as the PMC collision cooking is far too slow for my project. I’d recommend trying the RMC as it’s usually a nice boost in both memory and performance over the current PMC in the engine.
