motion sickness and nausea working with unreal engine

First unreal engine is awesome, but i have a question!

When I’m working with Unreal Engine, I get headaches, and when I show my project to some people, they also get sick.

I’ve already turned off motion blur and tested various anti-aliasing options.

I play FPS games and never have problems with games like Battlefield, CS, etc. Games made in Unreal make me feel sick; the only game that doesn’t make me sick that uses Unreal is Delta Force.

Games like Gray Zone Warfare also give me headaches.

I really want to find out the reason for this; if anyone has found a solution, I would be grateful.

My config is high FPS and motion blur Off
