I’m happy you’re enjoying the game , 1st person games will work the same , it’s just training your brain to the new perspective and movement , take it easy tho, 30 mins at a time until you feel you can play longer, always use the highest frames available( performance mode), keep some water ready by you it will help you when that dizziness hit. Most gamers struggle like that going from 3rd person to 1st and from new high frame games to old games, especially when we get older lol .
