That is true. So don’t render at an FOV which is 25% larger.
We already know the 12K will have adjustable FOV. It’s an easy guess that it will have an FOV setting that is similar to the 8KX. So use that if you’re trying to run the same settings as you were running before on an 8KX.
On the 8KX, the extreme edges of its widest FOV are blurry. The same is likely to be true on the 12K… only those edges are further out. The implication is that if you restrict it to the same FOV as the 8KX, it’s probably a lot sharper out to the edges than the 8KX at the same FOV.
I’m hard pressed to think of VR games where peripheral vision doesn’t matter. I mean, yes, you’re focusing on the center portion most of the time, but usually when something that matters comes up in your peripheral vision, it matters a lot.
I say this right now having just come from playing Contractors VR where I was dominating a bunch of enemy players with a 7:1 kill ratio in terrain where I could sneak around in the weeds. I was absolutely taking advantage of the 8KX’s FOV and fidelity and my knowledge of the enemy players’ narrow FOV limits. I could see them trying to flank me and sneak up on me, but they could not see me doing the same. It was really unfair.
Even for something like walkabout mini golf it makes a big difference because I can easily see the hole and the ball, whereas my Index wielding friends can only see one or the other at a time.
When I’m playing co-op VR games with my friends, I routinely spot stuff they missed. Objects on the ground that they just walked past because you have to constantly pan and scan with a narrow FOV headset, and it’s just much easier to miss stuff.
A very typical exchange when I’m playing VR games with my friends goes like:
Friend: “How did you spot that?!”
Me: “Pimax.”
Friend: “Pay to win! Cheater!”
Me: “Yup.”
I have to agree with that. I formerly had a 2080 Super, and I waited until I got a 3080 Ti before buying an 8KX. And even the 3080 Ti can’t max it out. I think the 2080 Ti is around the bottom of the range that can reasonably drive an 8KX, and admittedly that makes my comments about still being able to run a 12K and get more out of it less true in that case.
If I had less than a 3080, I’d put my money into upgrading the GPU before upgrading from an 8KX to a 12K.
