Testing the 2080ti with the 8kx

Hi Pimax,

Can you test if the 2080ti can push 4k x 2 @ 90hz natively? I don’t know if you have an 8kx prototype. If not, you can bypass the upscaler to send a signal to both panels on the 8k.

If preliminary results prove positive, then we might yet see the 8kx released sometime next year. How awesome would that be?

There is no -x prototype. You can’t bypass the scaler and single bridge chip, and the 8K doesn’t have inputs for the two wires that 2x4k@90 requires right now. The -x is a well into the future dream, that will probably need far more than 2080ti to drive it at full FPS.

The 2080 TI is only about 30% faster than 1080 TI. Its cracked 4K 60 in most games in 2D. 4K 90hz in Stereo 3D is a pipe dream at this point, unless you had 2 2080TIs with perfect SLI scaling, and SLI doesn’t work in VR unless Developers support it.

If it were me, I would just get a 5K+ and forget about the 8K.

You’re not taking into account DLSS.

With the 2080ti! 20asdaf

DLSS is native 1440p resolution that is intelligently upconverted to 4K using machine learning from 64X MSAA datasets computed on Nvidia’s Saturn V supercomputer.

Digital Foundry did a review of the footage and said that it looked “better than checkerboard rendering,” but noted that you can tell its not native resolution.

Nonetheless, you point stays valid, the 2080Ti won’t be enough to feed 2 x 4K screen at native resolution and at 90 fps (even at 80 fps if it stays the same limit than the 8K).

But it hasn’t been tried. It’s hard to say a definite no until it’s tested.

You are correct that hasn’t been tried… what you are missing is that it can’t be tried right now… the only people that might have an 8kx is the people at Pimax.

It is still a prototype, which means it barely if at all works. We are looking at most likely a year before they have something presentable.

So the answer is, No for right now. Later we can re-evaluate, after the 8kx has become more than a prototype if it exists at all.

Edit: Added the possibility that the 8kx may not even exist per @neal_white_iii

Actually, I don’t think that Pimax has built a 8KX prototype yet. They said that they are focused on releasing headsets and accessories to backers. After that, they will work on the 8KX.

Won’t repeat all my arguments of the 8k vs the 5k+. But if you stick with the 5k+ and a 2080 now you save 400$ vs a 2080 TI. In a few months this give you a great rabate for any new hot headsets with FOV rendering that will compete with pimax offering . I do think that we will get a better offering than the 5k+ or 8k in less than one year.

[/quote]Saving 400$ to put it in another headset might look good (is it ? do people plan to change headset every year ?), but choosing the 2080 for future investment defies the logic of going for a better headset which will requires an even more powerful GPU.

The star vr one is a better headset in some aspect and was certainly not working with the 2080 Ti. FOV Rendering should reduce the requirement for a powerful gpu. The logic that the most costly Gpu must buy both for large FOV vr is certainly not a logic that most people can afford even those with a meaning full amount of cash to put In this leasure.

A few month could be 1.5 year by the way, this is the life expectancy I give to the pimax 5k+

I’d bet a beer that it looks better than the scaler in the 8K…

My bad, I misunderstood when you said FOV rendering. FOV anagram is usually meant for Field Of View, like the large one of the pimax headset, star vr, etc. What you meant was probably “foveated” which will obviously lower the requirement for VR.
But talking about fovated rendering, pimax should be able to do that once the eye-tracking module is in place (yeah, it’s not out yet, but neither the starvr which, by the way, isn’t targeting the general public, only professional at the moment).

Sorry was ambiguous should I’ve said foveated rendering…

Hmm… water cooling doesn’t seem to help the 2080 Ti =/

The RTX lineup is a crappy series. A $1200 card that is 30-40% better than a $630 card. Thats just bad.

True, but it’s the best currently available. You always pay more than it’s really worth, to get the “best” PC components.

What upsets me with this series of cards is that they clearly went for Ray tracing when it wasn’t ready, and with the GPU die as big it is, they could have put way more shaders and ROPs on this card.
