Would seem Linus is getting about 20 FPS on Tomb Raider. I wonder how low the FPS would be on Second life with an 8k computer...Would it run? or just crash.

I'll bet the viewer's 512MB texture memory limit really helps there.

I'm pretty sure it actually would - it would mean the video memory wouldn't be full of oversized in-world textures so it would be available to drive the monitor pixels, which is a completely different operation.

Still doesn't change the fact that the monitor in question has more pixels than the human eye has cones (the structures it uses to form an image) - in fact, it has orders of magnitude more.

I didn't watch the Linus video, but 20 FPS for the new Tomb Raiders is unacceptable. Also, 8K and even 4K are overkill for most games. When it's fast-paced, higher FPS is always better than more pixels.

Is that really the texture memory limit in the current, official SL viewer? I know that in Firestorm the limit is 2 Gb.

And, would a higher limit really help for SL? In 8K everything's just bigger in size, not bigger in number of textures.

Human eyes can not perceive 8k, so it is a gimmick.

The healthiest human eye won't be able to see a difference even on a 300 inch screen.

It's a bit more complicated than cones vs. pixels. Cones (4.5-7 million, depending on who you ask), and the far more numerous rods (about 20x cones), are quite unevenly distributed about the retina. The central fovea (0.1% of our visual field) which has the highest visual acuity, contains almost all the cones and none of the rods. It takes three (four for tetrachromats like me) cones to match a display pixel (which is actually three sub pixels (red/green/blue), so it's fairer to state that our cones are equivalent to 1.5-2.3 million pixels...

...until we consider "hyperacuity". In addition to raw pixel density, our visual cortex does some pretty cool processing to improve resolution. Some of that magic is thought to involve the eye's rapid eye jiggles, called "saccades". High end digital cameras are now starting to use their image stabilization systems to mimic that jiggle, producing images with higher resolution than possible from pixel count alone. 

A display screen doesn't know where we are going to focus our attention, so it must meet or exceed the spatial resolution of the central fovea at all points if it's going to be indistinguishable from "reality". If the fovea's 1.5-2.3 million pixel equivalents occupy only 0.1% of our visual field, it would take 1.3-2.3 billion display pixels to match it. That's all theory though, and in practice we've been quite happy with far fewer pixels on our televisions. Even so, I recently saw an 8K TV right next to a 4K and, from a comfortable viewing distance, the difference was obvious to me.

They said that about 720p vs 1080p too.

And then there are the millions of poor bastages like me who have Astigmatism. :S

Odd thing is, I have better night vision than most people who have 20/20. Between the two I avoid driving at night as much as possible because those oncoming headlights blind the living *bleep* out of me. If only surplus Sherman tanks weren't so darn expensive.

I got around to watching Linus's video. That 20fps on Tomb Raider was with $15,000 of Nvidia Quadros driving the display. I get the feeling it'll be a while before I make the jump to 8K gaming.

I also have a li'l astigmatism, which is exacerbated by high-contrast environments, night-time being the worst. I like to watch movie credits, to see the names of the people involved. That sometimes requires me to turn up the house lights to drown out the secondary images.

I do dream of driving down the road in my tractor, pushing or lifting obstructions (like cars, bicyclists and moms pushing strollers) out of my way.

It's not a factor of said or speculated. It a fact about how our cones and rods can detect and see detail such as pixels. It is not possible. A perfectly healthy eye can see slightly over 4k if perfect in the 50% of central view. . But 80% can not even see perfect 4k with our normal field of view. The very center of the eye has the best perception in a very tiny space, then lessens greatly . Looking straight on at a monitor your finest tune of view at a screen you can completely see is only the center 1/8 of the screen in high detail. Your eyes details is 1/2 that another 1/4 from that center. and less to the outer edge of site. Many may have had similar eye tests done that you can plainly tell that. It's the way are focus works combines with rods and cones for color detail and image details. 

At this point what matters is stability and smooth frame rate at current 4k. As well as contrast, and good HDR. Detail in textures and the separations are important. 

All of it is useless in Secondlife unless they get well beyond the current limitations. 

THe 8k topic has already been well discussed and the factor and limitations of our own eyes clarified. THe higher resolution can help with extremely large displays , but face the truth, 30" and below gaming screens are useless for it, and hardly beneficial to 4k. While I do enjoy 4k, HDR gaming, I am also playing on a minimal of a 58" HDR screen. 46 and less is not even a benefit, even tho super scaling can help with some fine details. . 

Your eyes has a vary narrow view for high resolution and the large screen has to be a good distance away from you to have any benefit.

There are about 5 different types of Astigmatism. Didn't need to start wearing glasses until I was in my 40s.

You crack me up.

Five or so groups is probably all that's needed to work up acceptable solutions. There are, of course, as many kinds of astigmatism as there are eyes that have it. I first started needing glasses for close-up work about 15 years ago (I'm now 49). I expected that as a result of the nearly inescapable presbyopia. One day, as I was looking at a blinky light in my lab, I noticed it looked like a comet, not a dot. Something was blocking my view, so I moved my head a bit to get a better look and it returned to being the expected dot. I quickly realized that my left eye was the culprit. I knew enough about optics (studied it and I'm am amateur astronomer) to recognize it as a cylindrical astigmatism and was able to estimate the degree of correction (angle and magnitude) needed to fix it. I went to an eye-doctor, described what I'd determined, and was roundly dismissed... until she finished the tests and confirmed my estimation. Had I known "which way is up" for astigmatism angle calculations, I could have written my own prescription.

I switched to a different eye doctor after that visit. He loves to trade book recommendations with me, and happily confirms the diagnoses I bring to him once a year. He's good enough at what he does to not feel threatened by my ability to do a little bit of what he does. He e-mails me the images of my retina from his fancy machine and I make canvas prints of the interesting ones, to hang as abstract art in my home.

Yep VR and Swagbuck's.

I think she just won some Swagbuck's!

I don't see VR taking off until another decade unless they somehow lower their prices. Still 500 bucks too own a oculus rift..

Let's go to the Best Buy website and shop for 8K televisions. There's one selling for $8K!  I'm not sure if I have enough swagbucks!

As long software still not support lsrger fonts on 2k screen. Why think about 2k or 4k nit to think about useless 8k. Things are only harder to read.

For flatscreen gaming everything above 2k sounds useless.

You are misinformed . Firestorm has a limit to 1 Gb . and it blurs some images

It in my computer , can you explain this ?  ( of course my graphic card is not limited to 1GB in hardware )

Hey, I asked you first. :P But let's agree then that FS has a texture memory limit of 2 Mb on some computers, rather than claiming that people are misinformed.

depends on your card's total video memory. 

So, for 11 Mb video memory, FS puts the ceiling on 2 Mb, apparently. On my previous computer, my graphics card had 512 Mb, and FS put the limit there on 512.
