I'm someone who has always been highly sensitive to motion sickness. When first-person shooters started to become popular it could get really bad for me and because of that I always preferred 3rd person games.
I had issues early on when I first purchased the Oculus Quest 2. I eventually was fine with every game I owned on that platform and overcoming the issues in some cases was due to a setting change or how I moved my character.
When I got the PSVR2 I suffered when playing Horizon Call of the Mountain, but eventually learned how to manage that. With that game, it was less about a setting change. What worked for me was taking a break every 15-20 minutes. I don't mean to take a break by leaving the game. But I would stop moving my character and find myself a visual point off in the distance. Like a mountain top miles away. I would focus on that mountain top for a couple of minutes. Then I could carry on for another 15-20 minutes without getting motion sickness. That game was totally worth doing anything I could to combat the motion sickness.
I have been able to play GT7 for upwards of 6 hours straight without any issues. I just sort of skimmed through this thread. I plan to watch the video above, read through all the comments, and do some testing today and will report back if I have any tips or suggestions.
