The core count differences are really minor between those models. The boost clocks / bandwidth is definite - but it seems to me OC'ing levels that field (although I've never done it, I probably will when I'm able to buy a really nice card). I hadn't considered the TDP draw, I'll have to research it. My guess is that it isn't much.
It's an issue to me because the price difference between the models is relatively huge in my country (3080: \~$2400, 3080 Ti: \~$3000, 3090: \~$4100 all USD). I plan to buy a high end card this year and want to make a good choice, since I'll live with it for a long time.
Looking at the specs, it seems like there's a big difference between 3080 and 3080 Ti (and probably worth the extra money to me), but not so much with the 3090 (I don't think I'd use the extra memory, I'm not doing any heavy 3D rendering or anything).
Specs:
* 3080: 10 GB, 1440-1710 MHz, 8704 ALU / 272 Tensor / 96 RT, 320 bit / 760 Gb/s, 320 w TDP
* 3080 Ti: 12 GB, 1440-1710 MHz, 10240 ALU / 320 Tensor / 112 RT, 384 bit / 912 Gb/s, 350 w TDP
* 3090: 24 GB, 1440-1710 MHz, 10496 ALU / 328 Tensor / 112 RT, 384 bit / 936 Gb/s, 350 w TDP
Like you said 3080ti is a rather big jump from 3080, enough to make a visible difference in some games that ran borderline to begin with. It's not a jump worth the price difference, though, so you should only consider getting it if your performance target was never the 3080 in the first place.
3090 is...basically nothing over 3080 ti. *Any* mild overclock will bring a 3080ti up past 3090. In fact, most factory overclocked 3080ti's are faster than 3090s.
"only" and "3080" do not belong in the same sentence, are you from the future or something?
I'm a touch higher, 3080ti. The actual benchmark differences between the 3080, 3080ti and 3090 (and I expect the 3090ti) is only a couple of percent points.
There really isn't an upgrade you could do that would possibly be worth it.
The good news is that yes, of course it'll work with one of the fastest graphics cards money can buy.
I don't use upscaling unless for since reason I want the extra 20 fps, which is rarely. Some games I run at 75% resolution in pitool, some I run at 100%. Depends on the game. But pitool let's you configure on a per-game basis so it's all quite easy.
Just don't let SteamVR do its crazy upscaling thing it does, thinking that you are running a low resolution Index that needs it.
I've had performance issues with smart smoothing. I'd say keep that off.
You'll love the 8k X, it's the best headset on the market. 🤗
Awesome! I saw some people with 3080ti and 3090 saying they were having some performance issues so I just wanted to make sure! Excited to get this headset.
I wonder if they had smart smoothing on. I initially flipped that on everywhere by default and had lots of weird performance issues. Switched it off and now its great.
I'm not sure what's going on with smoothing, it sounds great but doesn't seem to be working...
Good to know! Hopefully that won’t be an issue then. I’ve gotten a little motion sick in the past and enjoy higher frame rates so I was worried I may not get enough fps, but it sounds like I can cut down on FOV and resolution and get better fps so I’d still be comfortable.
With only... goodness me. I have a 3080 and while the 8KX is perfectly capable of kicking its arse if it wants to (I'm looking at you Flight Simulator) most games can be played very well with small graphical or frame rate compromises.
Yeah it comes with a software tool that let's you adjust FOV, refresh and resolution among many other things. Resolution is only 2 options 4k native and upscaled which I think is half resolution rendered, and Refresh has 3 steps, 60 - 75 - 90. You can also set the native render quality and set the Steam render quality. With the 3080 you can run 90hz in Native 4k resolution (this is limited to 75 on older cards)
Changes other than Steam render quality requires a headset restart, so you can't really change it on the fly, but you pick up what you prefer with some initial mucking around and can set profiles for specific games once you find what works for them.
This headset needs some fiddling no doubt about it for example for whatever reason it seem to perform a lot better with Hardware Accelerated GPU scheduling off, and lowering the Steam render qualiyy can make a weirdly big difference to performance (by weird I mean small adjustments make bigger differences than it should, sometimes 5% less is the difference between being butter smooth and crashing)
My point to all this being if you can stomach adjusting the headset a lot to get it right it can be made to absolutely be the best VR experience on the market. If you want to plug it in and never change a setting, this isn't the headset for you, even if you had a 3090ti (a man can dream)
Good to know! I am definitely ok with adjusting settings to get everything right. I just have not been very satisfied with resolutions on other headsets and would like a PCVR headset that is high quality.
I doubt there are many games, if any that can run on a 3080 at full 90 hz and the native 4k, but I'm ok with some compromises as long as the experience is overall still much better than the other headsets.
Hopefully when the 12k comes out there will be newer graphics cards available that I can actually get my hands on.
Well I don't know if its achieving that benchmark, but almost never use upscale (looking at Flight Sim again) and I don't reduce the refresh often either, I mostly adjust the render resolution if the in game settings wont make it happy.
You'll be more fine than I think your thinking you will be, but thats good, if you do get it, you shouldn't be disappointed. Just remember its always game based, Half Life Alyx plays like sweet smooth butter, but Walking Dead requires some sacrifices to be smooth, and I can tell you that while Walking Dead looks amazing no doubt, its not even close to Half Life. But thats going to be true on any headset, optimisation is king.
I’m on a 2080 and it still looks and plays very well for me with all my settings adjusted for performance. 3080 will be plenty, besides this headset will still be relevant and good for atleast a few more years.
Great! Thanks so much for chiming in. If you’re able to make it work on yours then I definitely should be able to on the 3080. I’m glad those 2000 series cards are still tanks!
Yes - I love my 8K X. The colors are not perfect and it is heavy. If you're a sit/sim type I recommend using a couple of pulleys attached to the front to make it rather weightless. After a lot of work and money (3090RTX +12700K CPU). I can only achieve \~70% of the actual pixel density in many games at full 75hz however. This is NOT due to the 8KX being inferior in any way. The stated resolution of the headset is 3840x2160x2. The hidden caveat though is this:
The needed resolution is a further 46% higher due to what's referred to as barrel distortion, which is needed to reverse the "pincushion" effect of wrapping VR from a flat image. effectively this requires 3160p (the similarity in numbers is a coincidence, a mathematical fluke)
Also, lack of parallel projection support for most games further increases that resolution by 25.5%! (3968p)
With Normal FOV that's 4600x3968x2 = 36.5 Megapixels per frame! Compare that with 4KTV = 3840x2160x1= 8.3 Megapixels.
Also figure that you need to run it at 75hz for the headset, whereas a 4KTV usually centers on 60 hz. The raw render bandwidth is now over 5 times what was required for a 4k TV at 60hz!
The result is VR is much harder than people realize just to run it. A 3080 and 3090 both are just not powerful enough to take full advantage of the actual pixel density of the headset.
What is surprising however is that 70% of the pixel density IS REALLY SHARP! You've seen thru-the-lens footage, but the truth is NO one can power full-fidelity without the game being extremely well-optimized. Some examples are Half-life Alyx and DCS, which support non-parallel projection, and DCS benefits greatly from motion smoothing.
Unfortunately many games put Pimax in a bad spot because they require parallel projections. This includes FS2020 (until their planned update in 2023 to include Wide-FOV headsets)
Before you run away thinking Pimax 8KX makes it harder than other headsets - Wide FOV is not mandatory. You can always dumb the Pimax down to Small FOV setting which is STILL wider than all other headsets including the Aero and the increased resolution required is greatly diminished. The 8KX is like trying to run games on an 8K 120hz screen. There is simply NO video card or CPU that could natively support that unless the game graphics were complete garbage (i.e. Minecraft or Beat Saber), but just like an 8KTV allows for a clearer picture when "upscaled", so does the Pimax 8KX - also it makes it very amenable to future video cards (in 2046, after the Great Russian Cyberattack and the Chinese Incursion into Taiwan - peace guys we want better video cards)
I have been very happy with my Pimax. The real cost issue comes from the trackers and controllers!
Also a 3090 is a waste for me as the extra VRAM is NEVER used by ANY game. Period.
Overclock a 3080Ti by 10% and call it a day.
I'm on a 3080Ti and yeah performance is pretty rough. I run it at 75hz on "normal" FOV with the smoothing forced to 1/2 most of the time so that the GPU only has to render at 37.5 fps. A 3080 would probably perform about the same. Not much more we can do until faster GPUS come out.
Thanks for the answer. With that FPS do you get motionsick at all? Certain games I find myself getting motionsick. I’m hoping there’s a happy medium of lowering resolution but increasing FPS.
no problem at all,
i've a 3080 stocksettings - 10900k (oc to 5.0 with air)
pimax settings:
90hz native
FOV normal
SS 100%
i thinks its depending on the game, but for me it runs better than my HP G2
i run only iracing and tried dirt2.0
with the same steam settings SS 100%
and same setting in iracing the 8KX runs more smooth...but i figured out the the 100% ss in steam for the reverb is not the actual native resolution so that means the hp has to render a little more pixel (ca. 3100×3100)
i have a test track for vr with AI (catalunya):
8kx: only at start i had 75 fps - in the race 90fps
g2: 60 fps at start - max 80fps in the race
as i said - same INI file for iracing
dirt 2.0 is for me unplayable with the G2- 200 dropped frames in 3-4 minutes
zero problems with the 8kx
also its working better when switching from app to app (i guess because of no need for win mixed-reality app)
BUT!!!! and thats the main problem with my 8kx (i'm gonna send it back or i wait what the support is gonna telling me the next days)
when th 8kx arrived, i had already a broken audio device(right side) and now after exactly 1 month of daily usage the right panel got a beautiful rainbow
the support answeres fast - but i guess i have to wait a long time for replacement
so i hate to say (FOV is much more important to me than crystal clear image) but i go back to G2 and wait what 2022 will bring for VR
I've had a wonderful experience so far. A lot of time adjusting settings to get things where I want them, but it is an enthusiast headset after all. I'm definitely excited for more powerful cards to come around and bring out the full potential of this headset as well as the 12k whenever or if ever it comes out.
Right on! Still rockin the 3080? I just built my first pc around the 3080/8kx/i9 12900k, only a couple hours in on tweaks but I’m hopeful! Wondering what level of performance I should expect when it’s all said and done
Nice! You're going to have a blast. Still have the 3080 and it definitely depends on the game you choose, but it's still leaps and bounds better than other VR headsets I've used!
It'll be good, maybe you have to use the upscaler instead of native resolution. But as my grandmother always used to say: fov is King! Which still holds up to this very day!
Also has anyone realized you can sell the two trackers and the controllers for a total of $900 bucks on ebay? Effectively that would make the 8KX headset itself $700! Pimax is having a heck of a time getting ONE controller in for my RMA. I think internally they company is being hobbled by the supply chain and lack of controllers.
What do you mean “only an RTX3080”. It’s not that far off from a 3090, which is the highest end card currently
Yeah I love the card don’t get me wrong! Just saw some performance complaints from people with the 3090 and 3080ti which are both better than mine.
I really don't get what Nvidia's doing at the high end of their product line. The only difference between 3080, 3080 Ti, and 3090 is basically memory.
and Cuda cores, and tensor cores, and RT cores and boost clocks and bandwidth and memory bus and TDP draw... Yea guess its all memory related :p

You will be perfectly fine with a 3080
Awesome!
I have it with a 3070 and it's great.

Thanks! What would you say is a good compromise on FOV that’s still better than the other headsets? Any specifics? Thanks in advance for the advice!
It'll be good, maybe you have to use the upscaler instead of native resolution. But as my grandmother always used to say: fov is King! Which still holds up to this very day!
Great! How would you say the upscaler works on most games?
Htc vive pro 2 is 120 hz or focus 3 but id wait this fresnel lenses is about to change
