Update: It seems right before crashing, the program goes into 'program not responding' state, and right after that, just closes itself without any message.

To what I have tried to fix the issue myself(by then I didn't know the problem was tablet):

Hi, thanks for replying.

Try to run the game without the tablet (and tablet driver). For me it fixed my crashing issue.
I posted separate thing in the feedback tracker, if you interested about more detailed info.: https://feedback.bistudio.com/T123032

I agree with this. Although situational awareness of outside of scope may be minimum, at least you can notice really big thing. But still I remember RO style of 3d scope is very unrealistic.

And one more thing, we need to know that the cameras and the eyes are different. I mean you should not believe pictures are same as in RL.
