Well then, I'm kinda stumped. If there is no override that turns vsync off, there might be a setting to force it on. But for that you'd need to look at your GPU settings. Unfortunately that's all I can say for now.
I'm a 3060 owner as well. Unfortunately, it's not just this, many other games are broken for me as well. I can't even play Borderlands 2 or Helldivers 2. However this problem doesn't occur to me so it might just be you. perhaps a bad cpu and gpu pair?
