[ouyangzhuzhu]

hI~,all:
WHEN testing ,we can set the fps by [--fps FRAMERATE] in command line,
but now i want to change the fps when training, how ?
I tried modify the vizdoom_wrapper.py and change the fps from 35 to 1000 and then modify the common_defaults.yml by changing from "display：false" to "display：true", so i can observe when training, but i can not see the image go any faster from my eyes....can u help me? Did i do the wrong modify? what can i do....3ks ,friends~~

def init(self,
config_file,
frameskip=4,
display=False,
vizdoom_async_mode=False,
smooth_display=False,
fps=35,
change to:
def init(self,
config_file,
frameskip=4,
display=False,
vizdoom_async_mode=False,
smooth_display=False,
fps=1000,

and i found that if change the threads_num in a3c_defaults.yml smaller, the image will go quiker when training, this is why?
