Alot of people hav motion sickness. Its anoying and so butt i think i got the solution. Look at it this way.. minecraft enderman. U look at them Ingame and theyr angry. But look at them in real life and u can stare at them without the game knowing it.. or
Battlefield... an enemy on the left. U move ur eyes to the left and u see him. This is also with the vr. Maybe in the future they can detect eye movement and optimize the screen cuz this must be the problem. & it would also improve gameplay reality...
Another good example is there are 2 men standing 5 feet away + a star in the middle. Look at the star and the rest is blurry.. but when in a game u have the oppurtunity to move ur eyes but not the game.. u now must see where im going... and it even is really easy cuz the only thing u need is like some sort of detection and software coding to let the screen move with the eyes.
There is no one fix for all for motion sickness, the problem is different things affect different people and in different ways, the day someone does come up with a one fix for all they will be instant billionaires.
