Sorry to have to do this again but it's very hard to come to reliable conclusions on this.  I have a new 3080Ti unopened, won't open it til the pending performance update.  But now, if you're running Ultra settings on either of these or other 12Gb cards please let me know what you're finding in the worst areas of the sim.  I'm also running vsync at 30Hz so limited to 30fps which helps GPU load immensely but has no impact on reported VRAM use.   Please also report your Render Scaling setting and also T-LOD and O-LOD settings which have big impacts on VRAM.  Please also only respond if you are using a 3440x1440 display.

Thank you so much I'm loathe to commit to keeping 3080Ti if it won't cut it longer term, however OTOH the massive weight and extra cost of 3090 doesn't appeal to me a whole lot either, hence the confusion.

Dont you think you should wait till the 27th Noel?

The most i have seen is use is Orbx London, orbx London city airport parked at that airport. Setting Ultra both LOD's you list @200,  RS 110, 1440p = VRAM 9975.

Since RAM and VRAM is going down, you need to wait to see how much. Your jumping the gun 🙂

I have seen 3090 people report 14-16GB. But that 4ks or even VR. So more than you run.

Yes I am jumping a bit David but that is because I am getting caught in a slight squeeze play because GPU prices are indeed slowly coming down.  Your report above, w/ a 3080 10G card doesn't seem to really apply well enough because you've hit the max your card can manage.  Yes I will wait for the 27th but still would love to hear from people w/ 12Gb cards as able.

Thanks 

 

 

I'm running a EVGA 3090 FTW3 in 4k @ NYC in Ultra settings and only seeing around 8GB max.

The most V-Ram I have seen been used is just over 9 gb on my 2080TI at 3440x1440 max ultra.

I would be so happy if we can see the numbers after SU5 as well. Like some of us I am also on the edge of deciding among 3090 and 3080ti for decent perf. with Ultra @4K(100). I thought 3090 was the only choice but even before update 3080ti seems quite similar in terms of performance considering the 12GB vram deficit? Did I understand correct that 3090 is a bit overkill on MSFS ? Please share your Vram findings after the update wth 3090 4K. Kind regards.

If I had a choice between the 3080TI and 3090 I would buy the 3080Ti.  The 3090 is like 10% more performance for another $400.  I was at Micro center when they received a batch and the 3080Ti sold out before I was selected. All they had left was the 3090 so I got it.

I've seen slightly over 11 GB on my RTX 3090 at 3440x1440p 100Hz.

Outside of the VRAM difference GPU performance for 3090 v 3080 Ti, at least in terms of benchmarks, 3080Ti is at least as strong and in Passmark is actually very slightly stronger performer.  And this is why I'm asking about VRAM w/ very specific criteria.  Intuitively, as our friend TurboKen reminds, my 2070 Super doesn't hit the VRAM wall very often so 50% more VRAM really seems like it ought to be good enough for my needs.  The cost difference doesn't bother me as much as 7lbs and 13" does!  Good Lord all for a lousy 12Gb more VRAM it's a bit hard to swallow.  I'm going to see what the performance SU5 brings which I hope will resolve the uncertainty for me.  I have yet to see solid emperical evidence 12Gb will be insufficient for how I use the sim.  Plus, and I'm parroting my own observation:  Xbox Series X only has 10Gb of VRAM available for the role of VRAM and I have to think optimizing is aimed at that, versus 24Gb or even 12Gb.  I think w/o upping the very poor cost:benefit Render Scaling > 100 the vast majority of the time the top 12Gb of VRAM in a 3090 very likely will never see an electron.  But as we know people always load up to the max wherever possible.

Here's what I mean about Render Scaling. Without looking at the RTSS OSD, can tell which one is w/ RS at 100, and which one is with RS at 140?

It is a hefty monster of a card. I'm on SU5 now and it's a noticeable improvement. 12GB should be plenty unless you just want to future proof.  I was reading an article today that they believe it will take two years until the chip supply is back to equilibrium.

Are you on 4K(100Render) with Ultra ? I wonder if RTX 3080 Ti is pretty enough with SU5 and keeps 30+ FPS all the time ? 

Thanks again for that.   Here is my forecast for what I need this GPU upgrade for:

1. I would like to move O-LOD to around 140, from 100-110 I'm at now.
2. Move T-LOD to 180 or so from the 150 I'm at now.
3. I would like to be able to always have Volumetric Clouds at Ultra.  Now I'm at Ultra, except at a complex airport when there is weather when GPU gets nailed to 99% so I will have to dial back to High on the ground, but nearly as soon as I'm off the ground almost always I can set clouds back to Ultra.
4. I have most other sliders at High now, and a few at Ultra like Terrain Textures and Vector data at Ultra.
5. I definitely want to be able to cope w/ PMDG NG when it arrives, but I'm thinking if DC-6 is any indication it may not be horrifically hard on performance.

I don't have any desire to future proof per se, just be able to run MSFS w/o the need to stop and adjust sliders that is the entire agenda for me.  I don't mind setting some sliders at High as the difference between High and Ultra visually is often imperceptible to me, at 3440x1440 16xAF, 8xSS.  Render scaling will stay at 100.  I say no future proof because my next full build will be about 4y from now, so whatever is high end then I will be looking for, and 3090 will not be high end at that point for certain.

Since I am not looking at 4-8k, and don't require all sliders hard right, I do think the 3080 Ti should be fine.

4k Resolution, 4K 100% render and Ultra.  LOD's maxed. 30FPS constant is doable. Sitting at a large airport on the tarmac is around 45fps , at altitude around 75 if I turn off Vsync. My 4k monitor isnt a gaming monitor so it's running @ 60HZ and I leave Vsync on.

Oh my god. I think I'am gonna hit that Amazon shortcut on my browser after seeing the SU5 ! Thanks friend. It was really good news for me.
