I'm ready to upgrade my 1080ti.  While it is more often than not up for the mission, I certainly have certain situations in P3DV5 where I find myself maxing it out.  VRAM is rarely a concern, but not never either.  This news is disappointing because in my mind the 1080ti would have been the perfect card.

These prices are ridiculous and remind me what CPUs were costing in previous years. One good reason why I'll be staying with P3D v4.5 as I can run in UHD with my ancient 1080Ti and still get great performance.

I was not able to find a 1080ti when I upgraded about 2 yrs ago, and still ended up paying a tad under R10,000 (all the Bitcoin miners apparently) but I am more than happy with my 1080 running my 27" LG LED Full HD monitor. Although it "only" gives 80 ppi, it is more than adequate for me still on 4.5 for the foreseeable future..

@IanHarrison, I had a 1080 before the 1080Ti and at 1920*1080 it's fine. But with the extra pixels of 4K (four times as many) the 1080Ti is really the minimum required. That's for P3D of course.

It might still be after the 5.1 patch comes out. An 11Gb card should not be brought to its knees by DX12.

Actually its not DX12 but settings and too high texture sizes Devs use for marketing reasons.

For sure.  I have the ability to prevent the 2 or 3 airports that seem to be the offenders from running out of vram, I shouldn't have to.  But for me the reason for upgrade isn't to get more vram.  that's just an added benefit

A good example is Madrid form LatinVFR. Unbelieveable how much VRAM this on eats.

I think any aircraft that uses true glass is also at present day a huge tax on VRAM.

I wouldn't be surprised if it's more because of PBR than texture sizes. Remember that PBR necessitates to the use of several texture maps, whereas non-PBR airports really only need one, perhaps two if you use normal maps. I have VRAM issues with OrbX's KBUR running 2048x2048 textures with PBR turned on. Turning PBR off on KBUR saved it. LatinVFR's LEMD being a vast airport. I can see it causing trouble. Of course, this would be less of a problem if textures were optimized to use smaller sizes in areas that are less apparent to the player, or one could use repeating textures where possible (not always the case though, due to the AO and shadowing effects).

Though I will add another observation. For whatever reason, while KBUR's PBR was still switched on, switching views really bumped VRAM usage up. I was sitting on the runway at FSDT KLAX in the default F22, and like clockwork, cycling views back into the cockpit would add perhaps 600MB of VRAM usage. As I was approach KBUR, P3Dv5 finally notified me I was out of VRAM when I tried to cycle to external view. I have no idea why cycling views between interior and exterior aircraft views would cause such big jumps in VRAM usage. Has anybody else seen this? Mind you it seemed to be vastly mitigated when I turned off PBR at KBUR...

Put my  Radeon vii under water, and could bring her up to 2100 mhz core and 1200 mhz RAM. And i have to say i have between 17-30 FPS @ 4K with 4xssaa but ist feels fluid.

And also no VRAM issiues 😉

but as you mentioned as nvidia is not available and or too  expensive i maybee also will stay with team red.

I do indeed see exact this vram behaviour on my end even with RTX titan 24gb. Switching views does add a lot of vram. You can't get rid of it anymore. I am also thinking LM does learn along with implement DX12. Maybe this is also new to them and therefore a little bumpy at the first roll outs of P3DV5

FYI -- if you are waiting for the 3080 20Gb version read this -- https://www.pcmag.com/news/report-nvidia-cancels-rtx-3080-20gb-and-rtx-3070-16gb-graphics-cards

Anyone own the 3090 24gb and using it on a 4k 50inch tv/monitor with 4xssaa?maintaining smoothness ?

im wanting time upgrade to this card from my 1080ti 

thanks

The screen size would have no effect on smoothness whatsoever.  What frame rate do you run?

I run at 60hz using rtss limited to 30fps 

buttter smooth with 8msaa but as soon as I switch to 4xssaa stutterfest with 4k.

it would be nice to use 4xssaa. 

To get rid of jaggies with 50inch monitor.
