my navmesh plugin, now working on path management for multiple agents for my demo ,i had 10 guards at one point each generating paths but without avoidance and still got around 512 fps at avarage. nothing big yet but i have been asking around on mikko's recast discussion group as to where find the new source and will be upgrading my recast source from 1.4 to the newest which has avoidance for agents ,crowd control and other goodies ...
