Editor runs slow. any way to reduce quality?


i have read system requeriments from here

i own an imac A1419 Late 2012 27", Core I5 2.9Ghz, 16GB RAM DDR3, SSD 128 and Nvidia GTX 660m 512MB dedicated vram.
i guess i´m inside the required specs, but can´t use Editor so well, it lags… Unreal Editor said me that there are some frame drops using it… so i would like to know if there is a way to reduce the editor quality setting so i can work better…


Head shot for that …
