The current FPSC cannot handle large, detailed areas with dozens of enemies and objects all around. You have to divide the map into smaller zones, kinda like rooms with some sort of "wall" blocking the movement and/or view of player, this helps alot. Also try having LESS than 10 enemies on screen at once, and make lights and objects STATIC without physics if possible (note that some entities like doors often have physics ON, eventho' they don't need it. Try turning these OFF too). Making characters and objects to spawn to the area when player enters a certain zone can also improve the performance, since these objects are not rendered right from the start.
I tested the 1.05RC2 with small (about 20x20) area with couple small buildings and about 12 enemies, some objects and lights, and everything played smoothly, even all the enemies followed and attacked me at the same time without problems.
