insane low fps

[sgt.maze2]

holy shit , i just played soul rebel and i was hitting 16 fps and constant 20 fps barely touching the 30s. I don´t know if it was the map but it was totally unplayeble and not just that map but also ramiel. My whole squad was also getting bad fps. I have a very decent pc gaming and i have overclocked my graphics card. Current performance for many maps is really damn bad.

PC specs:
1050 gtx
12gb ram
icore 5 2.5ghz

i am running with a mix of high on geometries,effects , medium on all textures and low on dynamic lighting while keeping medium the shadows
