Ok I found why it was not good in X64, I check if everything is ok, when compiling a Release target, then I'll be able to release a new version. It's very simple and it is just the filtering for a start.
I created a new thread as I restarted code from scratch, so there's less stuff than the old one ATM. Just the most important and main purpose of the plug , bump filtering. http://isiforums.net/f/showthread.php/20746-Real-Head-Motion-for-rf2-reboot-1-0?p=290168#post290168
