8K-X with RTX 3070?

Is a 3070 strong enough for an Pimax 8KX?

I would not recommend it. I am using an RTX 3080 and a lot of times I find I could get better visuals but the VRAM usage ramps hit its limit and end up with sub 1 FPS. Not that it isn’t great, it is. but sometime you want to have a little bit more room to play around with the settings. 3080 has 10gb of VRAM. VS 3070 with 8GB. On higher resolution VRAM is quite important. if you could afford a 3080 definitely go for that instead, sometimes i wish i went for a 3090, gives much more room to play around, but that price is quite steep.

I’m currently planning to wait for a 3080 Ti 20 GB card. That’s what I recommend if you can stand waiting a few more months. Also, try not to give in to the scalpers, since that only encourages them. Unfortunately, availability issues make that difficult.

I thought we here concluded the 3080 Ti would not be as high performance as an RTX 3090?

the 3070 is not the big VR Burner…

Ampere 3070

Turing

It probably won’t but it’ll be very, very close it seems and at what seems to be two thirds of the price it’s the one many (probably including me) will be buying… :wink:

Exactly my thoughts! 20 GB should be enough memory and the 3090 is only a little (~10-15%) faster than a vanilla 3080. The 3080 Ti 20 GB sounds like the best VR GPU value (at least if you’re getting an nVidia chip).

Pimax Vision 8kX users should not be buying their CPU/GPU hardware at the cost/performance point of diminishing returns.

If one is okay with paying 1500 to 2000 for a video card then that is fine, but there is in no way a requirement that you have to do that in order to make use of an 8KX. Of course buying the best available will always allow you to get more out of the headset but it would obviously work perfectly fine with a 20 GB 3080ti. Fact is that a game that you can’t max out with that card wouldn’t be able to max out with a 3090 either. Silly to imply that it wouldn’t make sense to buy something less than a 3090.

I will repeat what I said in the other topic.

Get any gpu with more than 16GB vram. 3070 and 3080 is not enough for VR and you will regret this very quickly. Next year there will be more titles with higher requirements. Think in long run not what is available today.
In ACC I’m already using 15GB vram with smart smoothing :open_mouth:

We are the early explorers getting into the real potential of VR right here.

Any reasonable estimate puts the number of Pimax Vision 8kX headsets in the wild at a small number, similar to the number of actual professional fighter pilots IRL. Even the developers of amazing resources like DCS World are lucky to get such hardware.

To have that, and not be equipped with the computing power to take best advantage of it, not just silly, but a sadly missed opportunity.

Wrong. Some games are already barely achieving 1.4x TotalSR with the Pimax Vision 8kX, while 1.6x, or at least more robust ability to achieve 1.4x might be noticeably better. Or even to be able to disable Smart Smoothing entirely at 1.0x TotalSR (no supersampling at all) in competitive situations.

Here we go again… :rofl:

Are You even reading what he’s saying?!

You still won’t be able to max out settings in most games and judging by leaks there’ll most likely be 5-10% difference in performance between the cards.

It’s funny, kinda… Weren’t You the one that said we didn’t need the extra power and now You’re all ā€œnothing but the absolutely fastest cryogenic yada yada will workā€ā€¦? :rofl:

Have a look at some of Your comments in that thread… :wink:

Fact is, every 1% we get in CPU/GPU power, we actually can put into higher resolution. Every time. These VR games run performance margins that consistently.

Thus, buy the best CPU/GPU.

Independent from that, it sucks that we can’t get enough CPU/GPU from available chips - lack of multi-GPU doesn’t help here - to banish awful Smart Smoothing.

Get it now?

I get that You think You’re there only one who gets it… :rofl:

Let’s just leave it at that, shall we…?

You do keep giving me that impression… intentionally? :wink:
(wisecracking)

Sure. Ironically enough, I was just watching a YouTube video showing a round of ā€˜Among Us’ …

EDIT: It also depends on the definition of max out. I vaguely remember now that fellow who thought ā€˜max out’ meant setting every graphics quality setting to maximum, regardless of whether there was an actual difference in visual quality, nevermind whether such differences were noticeable…

Yes Matthew.

It’s because I’m totally and utterly amazed and in awe by Your skills… :exploding_head:

Have fun in Your echo chamber… :rofl:

Let me add another take on the topic. The memory usage on GPU is often misunderstood. It is true that each company will spin its narrative (now it is Nvidia - you do not need that much memory actually, while AMD will tell you that indeed you are better set with more), the ā€œusedā€ memory usually means ā€œallocatedā€ memory, something the GPU can, but does not have to use, eventually.

You may believe that the games are actually appearing right now, or will appear in the very near future which make use of that memory, well, you may as well remember Rage, which used those famous ā€œmegatexturesā€ and apparently had 1TB of uncompressed textures (Remembering Rage, a flawed but technical marvel | PC Gamer). Surely it did not fit into VRAM back then and would not fit even now.

Or the latest Unreal demo with the streaming of LODs directly from an SSD.

The point I am getting to is that there is more than enough memory in current GPUs (with 10GB) to render the scene, but there is not enough memory even in 3090 with 24GB to cache all the game resources (for all the different operations). So what would really matter is:

  • the resource management (implemented in drivers and in the game engine)
  • the hardware throughput to handle the back and forth transfers.
  • the shader performance (compute throughput) to handle the high res renders (needed in high-FOV VR).

RTX 3070 will for sure be slower than 3080 or 3090. It will however not be slower because it has less memory, but because it is simply a slower card in everything.

@rallivr If you really want to tap into 8k-X potential, I would recommend going with 3080 or 3090. Now between the two, I believe 3090 is not worth the money, but this is just my humble opinion :wink:. 3080 Ti sounds like a sweet spot but no one saw one. I would not even dismiss AMD cards, if there was not the total lack of care for AMD cards from Pimax in the past.

Yes, yes it is. Disregard much of the spew already in the thread. People were running their 8KX just fine with a 2080ti, my 2080 does a decent job too. A 3070 will be fine bro. Yes you can do better, but for the same price? MAYBE an RX 6800, it eeks out just a bit more raw power than the 3070 in non ray traced rendering.

@rallivr, also check this thread:

True. I just want to have enough video ram so that I don’t have to worry about it, even with high levels of super sampling. I’m thinking 16 or 20 GB should be enough for this generation. I’m leaning towards getting a 3080 Ti 20GB, sometime in the spring, once availability improves.
