Anyone planning on getting the 3090 for VR?

[flameoutme]

I am super excited that the 3080 has 2x the performance of a 2080, and be priced at less than $800.

 

I'm a single player flyer and in the campaigns I typical fly it's definitely the 1080 graphics card that is the bottleneck, big time. Perhaps in multiplayer its not ... I don't know...

 

If you run a flatscreen at 1900x 1080 the card has to push out 2M pix. My valve index pushes out 4.6M due to it's resolution.

 

When I was doing a lot of testing using fpsvr I discovered that at 80mhz I could keep it at 40fps, but when I turned on the goodies in preferences the first thing that happened is the reprojection rate went through the roof, ****even though in the surface the fps was the same****.

 

When I ran the index at 90mhz, fps went to 45, but the reprojection rate was way higher.

 

 

So what I am saying is fps is only half the story. Reprojection is the enemy.

 

I want to crank up the details, and decrease the reprojection rate.

 

3080 here I come!

I definitely will be upgrading to the new 3090 or even a new Titan, but it will be in conjunction with a whole new box: Reverb G2, 10900K, Titan or 3090, pcie4.0 ssd, 64 GB DDR4 4400, 4k oled 48in monitor, more power...etc... It's all generational changes. I can't wait.

 

PS I've been delightfully surprised by the steady progress being made in the core DCS game, stuff is finally getting fixed afters years...

 

Keep in mind the 10900K (or any other available Intel CPU) does not support PCIe 4.0.

 

I'm waiting to see AMD's lineup of GPU's before deciding, but right now i'm thinking about getting the RTX 3080 together with the Reverb G2, hoping that they will be a good match in (single player) DCS.

I'm thinking of the RTX 3080 and the Reverb G2 too.

Hopefully that will make a big difference.

[Supmua]

The 3080 seems to be a very good deal, offering tons of CUDA cores (8704) even when compared to the 2080Ti (4352). It's no wonder there is such a big performance leap when compared to the 2080. Nobody in the right mind would want to buy the RTX 20 series now.

[GunSlingerAUS]

Yep, I'm jumping aboard the 3090 bus. Considering the 2080 Ti can't deliver high enough performance to get the solid 60fps needed to require the disabling of asynchronous reprojection in my Reverb (running at 60Hz mode), it looks like the 3090 should... provided the CPU doesn't become the bottleneck.

 

However, I don't know if the 3080 will be fast enough to run consistently at 60fps on the Reverb. I have a feeling it won't, but I'll be happy to be proved wrong.

 

But for me, I'm gonna have to reach deep into my pockets for the AU$2500 price of the 3090 to ensure ghosting and stuttering is gone for good. Now, when will I be able to order the Reverb G2 in Australia...

[FoxTwo]

Some mighty wild speculation in that post there friend.

[Supmua]

I think you would need a GPU that is at least twice as powerful as the 2080Ti to eliminate reprojection in VR. Probably won’t happen with this generation.

[speed-of-heat]

Count the cores...look at the vram speeds and the total vram... That is exactly what you have with a 3090

[GunSlingerAUS]

Well, given the specs, the 3090 *should* deliver at least a 50% performance increase over the 2080 Ti I currently run. Given that my existing card can comfortably deliver 45-50fps with decent graphics settings, the 3090 *should* average over 60fps. Which means no more ghosting (async reproj).

 

If not, I'll just buy two and hope that ED finally gets SLI working :helpsmilie:

The 3080 *should* deliver 50% improvement on the 2080Ti. The 3090 *should* deliver way more than that.

 

In WMR, I see no ghosting with motion reprojection on, but I guess that's been done to death already.

Yeah the 3080 is the new "ti" for the current series.

Many even speculate the 3070 will be on par with the 2080ti, but I doubt that is the case with anything not RTX.

 

What Nvidia is doing is bringing the Titan off the proverbial Mount olympus, and into the main brand as the 3090.

 

Nvidia is looking to get rid of the ti moniker entirely, what will happen is that in 12 months or so we will see the 3070 S and 3080 S as a mid generation refresh, perhaps with more Vram, but I would be surprised if they do.

For someone who has just upgraded a PC like me, and using a PCIE 3 motherboard I wonder if there will be a bandwidth bottleneck compared to the new PCIE 4?

Edited September 2, 2020 by BIGNEWY

[speed-of-heat]

the current rumor has a 5% overall improvement out of PCIE 4, on a 3090 as the bandwidth was not even close to being saturated on PCIE 3

That is good to hear, waiting for real world benchmarks now. :thumbup::music_whistling:

Do you have any links for you could give me? I'd really appreciate it.

It was on a YouTube video, I think it was gamers nexus, if it was it was an aside comment in one of his two videos on the 30x cards, if my memory is right.

[Mathius_001]

Thats the question I have, PCIE 3 allows 16GB/s, PCI 4 allows up to 32GB/s. The 2080Ti is capable of 14GB/s. The 3090 is capable of 19GB/s, surely PCI3 will limit the 3090. And as stated there are no Intel boards that support PCI 4. And even if there was its going to require new MB, CPU and the 3090. As with others awaiting the benchmarks and reviews to make sense of this mess.

Dont think it is that straightforward - 2080ti has only just saturated PCI-E 3.0 x8

 

https://www.techpowerup.com/review/nvidia-geforce-rtx-2080-ti-pci-express-scaling/7.html

 

"We are happy to report that the RTX 2080 Ti is finally able to overwhelm PCIe gen 3.0 x8, posting a small but tangible 2%–3% performance gain when going from gen 3.0 x8 to gen 3.0 x16, across resolutions. Granted, these are single-digit percentage differences, and you won't be able to notice them in regular gameplay, but graphics card makers expect you to pay like $100 premiums for factory overclocks that fetch essentially that much more performance out of the box. The performance difference isn't nothing, just like with those small out-of-the-box performance gains, but such small differences are impossible to notice in regular gameplay."

[Delareon]

To me the question is if there is a real difference in DCS VR between the 3080 an 90.

Im planning on a Upgrade, since i currently have a GTX 1070 both cards are a huge step forward anyways. Not just the GPU thats gonna be a complete system.

 

But there has to be a good impact on VR Performance for me to spend 700€ extra on the Card.

Currently i thought about the 3080 and spend those 700 to get an Reverb G2.

[speed-of-heat]

So there are two things currently "stopping" me looking at getting the 3080, ram and ram...

 

The first RAM; is the amount 10gb, is kind of where my 1080ti hovers in Dcs, and so I wonder if 10 will be "enough", that needs to be balanced by better throughput and compression technology...

 

The second RAM : is sort of related but I just keep looking at the pricing and the memory and wondering if a potential response to any AMD threat looks like a 1000$ card, with say 12 or 16gb of ddr6x, call it a 3080ti/super... Whatever...

 

I have no knowledge on the last and only supposition on the first... YMMV etc...

 

I suspect that a 3080 will be more than "fine"... actually I think it will crush it, in terms of GPU perf..

Would be useful to know how much ram DCS actually needs during VR gameplay. It may just fill up the coffers when it is available but only use half of it.

[speed-of-heat]

It seems to be 1gb less than you have.. I have 11 I'm nearly always at 10, when I had 8 I was nearly always at 7

[TBAR]

Thanks, I'll take a look.

[dawgie79]

If you already have issues with performance in DCS and have a 2080ti already, I wouldn't expect a big leap after throwing in a 3090.

 

Fix your pc first, I would say.

[Vullcan]

I disagree, DCS performance in VR (especially multiplayer) is... poor. Even if you have a 2080ti you can struggle to maintain 45fps if you want to enjoy the "bells and whistles" such as using 2x MSAA to eliminate shimmer, shadows, whatever.

 

Running FPS VR to chart the distribution of GPU & CPU frametimes will typically show the GPU is struggling to keep up with the CPU, until you start throwing in some crazy mission specific events (lots of units, GRAD spam, etc).

 

So yes I would expect a 3090 would significantly reduce GPU frametimes, and might even get them in line with the ideal 11.1 m/s for 90hz in something like the flight over tibilsi test.
