解锁30帧方法：
Go to Batman: Arkham Knight folder and find there Config folder
e.g. C:\Program Files (x86)\Steam\steamapps\common\Batman Arkham Knight\BMGame\Config
Now open with notepad (or use any other text editor) an ini file: BmSystemSettings.ini
Press CTRL+F keys on your keyboard to open "Search", paste this MaxFPS=30.000000 and press "Find":
Now you should edit 30.000000 value to set desired fps.
For example you want 60 fps, then this string should looks like:
MaxFPS=60.000000
If you want to disable sick motion blur:
Use search again to find string MotionBlur=True
And change value from True to False
Should be: MotionBlur=False
Save the file.
