I wondered why it could make me feel sick and found the following possible reasons: frames per second, field of view (especially if you sit close to the screen), mouse sensitivity, brightness. There are many parameters, but I think it's the mouse sensitivity, but maybe these are my local problems. For this, it is important to make game settings, but it’s not for me to advise you to make advanced settings (after all, I don't do the settings either). Thanks for music and game!
