Freezing / unstable framerate issues?

[Destroyedbeauty]

Go to your Advanced Graphics Settings and check for an option called SSAO. Turn it off if it is on - it should give you quite a performance boost without really affecting the overall visual atmosphere.

Other things include just lowering your other graphics options.

The occasional stutter is also caused by scripts being executed, probably a few as well. Like, if you were to witness a dust cloud popping up, the game needs to create it, play the animation, sound effects... it needs to load it 'on the go' in most cases.

Also, take a look at Problems B and F here: https://www.frictionalgames.com/forum/thread-3754.html
They may be able to help a little bit further c:

Though, I don't know why the game is stuttering at all. My laptop is specific for gaming - regarding the hardware in every way and inch - and can handle Battlefield 4 (just to take an example) without any stutterings on highest graphical settings et.c et.c.

Is it something related to OpenGL or someother non DirectX-related stuffs?
