You want to avoid textures swap as much as possible to avoid performance hit.

So makes sense to keep the VRAM being used to max with everything they can..

especially with MSFS 2024 I am glad I got a RXT 4090 back then with 24 GB VRAM and 18.000 cores, twice that of the RTX 4080 only 9.000 cores.

Test @ 4K, and this is not yet the most demanding situation: 

12.7 GB VRAM used

98 % GPU load

363 Watts GPU board power draw (MSFS 2024 probably best played only in the cold season  🤣)

good to see they are finally squeezing every little bit out of all 16 CPU- and of over 16.000 GPU cores to the max, as measured in GPU-Z. otherwise many of the new enhancements (a lot more data points for Computational Fluid Dynamics calculations offloaded to the GPU, ray traced shadows or animated vegetation to name just a few) wouldn't be possible while at the same time maintaining or even increasing fps/smoothness.

the 12 GB of the 4080 would already be VRAM limited for my tests with MSFS 2024 Alpha @ 4K, and this is not yet the most demanding situation:

The 4080 has 16GB of VRAM...

Besides that, I doubt that performance analysis in the stripped down tech Alpha have any meaningful relevance...

looking at the 98% GPU load tells me: the more CPU and GPU cores the better. finally. and that's what they have been aiming for - for a long time now - more efficient CPU multi threading and more GPU computing, to the max.

telemetry can hardly result in 98% GPU loads. new raytraced shadows, animated vegetation, massively increased CFD calculations etc. does increase GPU load though.

"The 4080 has 16GB of VRAM..."

right, I corrected that, thanks.

I sure hope so right now half of VRAM on this GPU hardly sees an electron.

Well, dont give nVIDIA any (!) reason why they should again release a x80 card with only 16GB of VRAM. Please 😉

@turbomax you could restrict your 4090 to below 300W and most probably would not notice a single FPS less. I have my 4080 restricted to 1.000mV and as such, never above 250W and performance wise I see no difference to use it unrestricted. Or simply reduce the power target down to 80%. You will loose only some percentages in performance but way less power consumption: https://www.tomshardware.com/news/improving-nvidia-rtx-4090-efficiency-through-power-limiting

same here for MSFS 2020, it seems MSFS 2024 has changed that.  

will have to look into that, thanks for the link:

the 5090 will have up to 32 GB VRAM according to:

Yes, but did you also read about the potential price tag of this thing? This is ridiculous...

The RTX 5090 price is estimated to be between $1,599 and $1,999,

we don't know that yet and $ 1,999 is not more than what I paid fpr my RTX 4090. but what I do know is that MSFS 2024, despite improved graphics etc. runs even better on the same hardware than MSFS 2020. therefore I see no need to upgrade. for the first time. well done Asobo!

https://www.pcgamesn.com/nvidia/geforce-rtx-5090-guide#

 

other rumors:

"... report suggests that the 5090 could end up costing between $2,000-$2,500"

https://www.techradar.com/computing/gpu/nvidia-geforce-rtx-5090-could-be-up-to-70-faster-than-the-4090-but-its-best-chips-might-be-reserved-for-ai

 

at an estimated 50% raw GPU performance increase over an RTX 4090 I would expect typically only 25% fps increase. probably not enough for me to justify  $ 2.000- $ 2.500 since the MSFS 2024 Alpha ran perfectly smooth @ 4K on my existing hardware. but this forum will be the first to find out. MSFS 2024 will keep me happy and busy no matter what. 😄

Should that be interpreted as being 100% stutter-free for an entire flight?  I have to assume not but you said, perfectly smooth which IMM means stutter-free.

my flights were all pretty short and only the default C172, yes smooth but without all the future graphics improvements it is too early for final results. so lets wait till November 19th, but I thought it was very pleasant, no frame counter and all those benchmarking gadgets.

I'm planning on replacing my 6800XT with an 5090, I might later upgrade my CPU to a 9800X3D with a new MB and 64GB Ram, I currently only have a 850W PSU, what do Wattage should a new PSU be, or world my 850 be enough wattage?

Sure.  Well, I've had two almost stutter-free (maybe 2-3 brief hitches during a long taxi) then not a single other stutter in a 2h14m flight in a row now in PMDG and FBW out of KDEN.  The most useful tact on this is to not start FSLTL until I'm ready to commence taxi and I think the 64Gb and no paging is *probably* helping as well.  2024 sounds like it will be that much better.  Anxious to see more VRAM in use.

See above, you will also be able to limit the powertarget of an 5090 as such that your PSU is sufficient. But considering that you are going to invest several thousand dollars anyway for the planned upgrade, it might be wise to add an additional 200 bucks to get a good 1000W PSU...

There is no completely stutter free in a flight simulator and certainly not in one that is partially streamed, that's just a fact !!!

And no RTX 5090 or whatever will help you in this case..

cheers 😉
