For anyone with a PS5 that has a really blurry performance mode
When I first turned on performance mode objects were blurry. I'm talking right next to me syringes were 50% larger due to the blurriness. I checked my console and VRR was set to auto. I turned it completely off and the blurriness is now gone. I cannot see as far without a sight but this was expected as resolution has to be lowered to get to 120 fps. Now the game feels smoother for me. I've seen a lot of everything is blurry complaints and just thought I'd offer what helped me.
Also, a couple other things- You have to have the proper hdmi 2.1 or better cable. Next gen consoles need these and usually come with them. Your TV or monitor also needs to support hdmi 2.1. A lot of setups do not have any 2.1 ports. Even some monitors that are 144 hz do not have this capability. I have 2 tvs that have 4 hdmi ports. Only 2 of the ports on each TV are hdmi 2.1 so I need to make sure I use one of them for my PS5.
