More VRAM helps a lot with DCS VR performance

[speed-of-heat]

Certainly on my 4K monitor that’s not the case. I see my 2080Ti being maxed out on VRAM in various 2D scenarios.

 

Can’t remember what res you are running in 2D.

 

Fair shout, and my panel is 2560 x 1440. If you are seeing double that in 4k that also aligns, as it's a similar pixel drive between 4k and the reverb at that level.

DCS runs butter smooth now. I have even underclocked the 3090 to save power and it runs cold and will serve me for many years. So happy with the 3090.

 

Very pleased to hear it

So as ED updates the core (hard work, I'm willing to give them slack), the goal should be to prioritize VR experience. It's more demanding so that's the high bar that they should attack.

 

 

 

 

Players also have to make sure their systems are not the problem, like GPU/CPU bound to avoid bottlenecks and optimization of the whole system for higher resolutions.

 

I don't know about Nvidia for GPU setting but AMD released RYZEN Master and it works rather well in gaming mode.

 

For Nvidia GPUs, the last edition of Afterburner allows for a precise allocation of VRAM use.

 

All in all, they allows for more efficient systems while playing DCS, and it is not the only issue...

Did some more testing yesterday. I only reduced render resolution settings to 100% which ends up with 2016x2240 per eye. VRAM usage dropped down to ~10.8GB. However, didn't do a longterm test and this drastically reduced visual quality and i still needed to force motion smoothing because CPU frametimes won't allow 90 FPS. Conclusion: the crispy sharpness of high SS settings - once you've seen it, you never want to go back. More VRAM opens up a lot of headroom to enhance your VR experience.

Yes, we had this discussion in another thread the other week but there was different ideas about this. My experience is about the same as yours, and I have found myself needing to lower settings a bit when I hade VRAM usage( or allocation) close to the physical limit of 11Gb and got a little stutter from what I at least thought was due to Physical VRAM limit.

 

I tried SS between 150 and 200 and found it sharpening the picture(= cockpit instruments) more the higher the SS, byt my OC:d 2080ti only had the power enough for SS150 to keep the smooth gaming that I personally needs to enjoy.

 

I dont have the slightest concern that the 3090 will add the headroom I would like

May be a good idea to sit and wait a month and see what AMD comes up with. Speculation about Navi is all over the place for performance (from 15% over a 2080ti to beating a 3090) but the 16GB VRAM buffer isn't really in question.

[RealDCSpilot]

Yep, this new generation of GPU's is the first one that doesn't struggle with highend VR. If the DCS engine gets optimized for todays CPU gen someday, we can go even further. Nvidia will also release a 3080 with 16GB VRAM, i really recommend waiting.

[Qiou87]

JI had this problem (switch of airplane after a while, get horrible stutter). So I "only" have 8GB Vram on my RTX2070S, 32GB system ram, but that's enough for my Rift S and I get smooth framerates when I start the game. Actually after a lot of trial-and-error I found that the problem dissappeared when I increased my pagefile size. For some reason Win10 had set mine to 2GB or something. I increased it to 16-32GB (flexible), and now the stutterfest is gone if I decide to switch airplanes on a server. Similarly I can do two missions without restarting the game in between. It seems the game likes to use the pagefile for some reason...

 

Just wanted to share since this "fix" didn't require me to use bots to buy a 1500$ graphics card. :)

[RealDCSpilot]

That's because windows uses the pagefile also to cache video memory to RAM and HD. It's called shared GPU memory. The performance impact comes when dedicated VRAM is full and a lot of additional HD activity is needed to constantly load stuff from the cache back to VRAM. If the amount of data is small, you may not notice any impact. If it starts to need bigger chunks of data to swap, the trouble starts.

And with the current 3080s being £800-900, a 16Gb will be? Maybe £1100-1200. Might as well buy a 3090 for £1400-1500.

It's $699 USD for the 10GB 3080

 

I expect a maximum of $899 for the 20GB, and possibly as low as $849 (based on estimated costs of 10GB of GDDR6) thanks to pressure from AMD.

 

That's still a few miles away from $1499.

 

I swear to god the amount of money you people consider to be insignificant is hilarious sometimes. Not to mention the fudged math and estimated pricing.

 

A 3080 with 20GB of VRAM will achieve 90-95% of what you can hit with a 3090 for far, far less money. Which you can use to buy a R9 5900X which will actually improve your frame rates due to it's superior single core IPC.

[AKA_Clutter]

AS I have a 3080 on the way, I hope I'm not too disappointed. That or the 3080 20 GB comes out within 90 days.

$699? Not in the UK it isn’t. See attached. Please don’t talk about fudged maths and estimated pricing. That’s exactly what you are doing!

Are those founders editions?

 

Stop comparing apples to oranges.

 

The Nvidia FE is 649 GBP.

Of course they are not as you can see. Forget the FE, I'm talking about realistic prices for more 'normal ' cards.

 

UK facts (all non-FE)

3080 10Gb - £800-900

3090 - £1500-1700

3080 20Gb (if exists) - £1200 estimate.

 

I'm not going to bother replying to any more of your posts. You've convinced yourself, and facts don't seem to matter to you.

He never said anything about Founders Editions, he simply gave a price range in the UK (a correct price range, BTW, for cards from the manufacturers that a lot of us prefer). I think most of us understood that. Not sure what is tripping you up. Also not sure why exact pricing is so important to you in the context of the comment you were responding to. It was simply to illustrate his personal reasons for justifying relative cost increase between known prices and estimated prices of a card that doesn't exist yet. His estimates differ from yours, but they're no more "fudged math" than your estimates are. Now we all know that he isn't talking about FE cards. Isn't context a wonderful thing? It helps if you attempt to understand the context of a comment before getting pedantic on somebody. Maybe what you meant to do was to politely ask, "Are you talking about pricing of Founder's Edition cards in the UK?" :doh:

It won't. It's not even announced yet, hell, it's only speculation at this point.

IF Nvidia releases an upgraded 3080, it won't be around for another year in my estimation.

[streakeagle]

Supposedly updated compression techniques make the 10GB of VRAM in the 3080 effectively larger than the 11GB of VRAM in the 1080 Ti/2080 Ti. If that is true, the slightly smaller VRAM of the 3080 should be a non-issue if the 11GB of older cards was enough. I would love to see someone lucky enough to score both the 3080 and 3090 compare DCS performance with both especially focusing on whether the extra VRAM of the 3090 is utilized to good effect or if they both perform about the same due to DCS Worlds ancient graphics engine and single core cpu optimization.

 

I originally planned to get a 3090 but based on what I know now, I am more likely to get either a 3080 or AMD. But if I knew for sure the VRAM on the 3090 made a critical difference with DCS VR and a Reverb G2, I just might eat the cost in money, size, and heat output of the 3090 to see the full quality possible on the G2. But it seems like other than VRAM size, the 3090 is only about 10% better at twice the price and given I am upgrading from a standard 1080, the 3080 or even the 3070 will be a huge jump forward at a fraction of the price.

[eatthis]

when watercooling and overclocking does it matter what version of a card you get? do they mostly have the same headroom for oc or are the different oc versions prebinned?
