I’m currently on a 1080ti on a 43in 4K Sony TV. When I’m in MSFS2020 in drone mode looking around I can hit over 9gb of usage. When in normal view it averages 8gb with heavy clouds. I’m also interested in P3Dv5.1 once it releases which can also be a vram nightmare. So will 10gb be enough. I’m hoping that in 2021 a higher TI card may drop with more memory.

I just came here to ask the same question. Beat me by 11 minutes

I was surprised that the 3080 did not come with 12 or 16 GB as the 2080 TI had 11. My 2080 Super already has 8.

I'm happy with my current system so I will be waiting for a "3080 Super" that has 12+GB memory.

That’s if they do come out with a Super or TI. This years naming, price and release is different than any other year.

If it is not enough then the software developers should be the ones to be under the gun to comply well within current hardware constrictions.

I think we need to be specific in what we want to know if it’s enough. For me I want to be able to run this in VR with the PMDG 737. This is where I need to know if 10gb is enough. My suspicion is it will run it but perhaps not on ultra settings. 

There should be a 20 GB version of the 3080 coming later. I will wait for it.

It can be argued that they already do, by providing the option to dial back features in order to stay within the VRAM limits.  A one-size-fits-all solution may well render the additional VRAM on an RTX Titan or 3090 useless if it's required to play to the lowest common denominator, or an automatic load-shedding feature may shed features the user would rather keep at the expense of others.  I'd rather they let the user decide where he wants to take risk or not, and on which features.

No, not if you want to increase visual fidelity to very high levels (who wouldn't) ... on my Titan RTX with 24GB VRAM, I demonstrated MSFS using 19GB, I demonstrated P3D using 16GB, I demonstrated XP11 using 19GB.

 

What is your conclusion?

Rob, from what your saying the 3080 won’t cut it if you want to go all out in any flight simulator. Hasn’t it always been this way anyway? We’ve been restricted all these years with the 1080ti and the 2080ti. We’ve just had to adjust our settings. Even if a unicorn 3080ti or Super with 16GB or 18GB of memory was released a year from now it wouldn’t be able to meet the demand as you suggested. The 3090 looks like the perfect card but due to either size, cost or power demand, I don’t see everyone getting one when a 3080, which is more powerful, affordable and 1GB less can outperform the 2080ti. I was eyeing the 3090 myself and it’s not a cost issue. It’s the size of the card and the thought of upgrading my [email protected] to something to complement the 3090. Finding a 10900k is impossible these days. The 3080 at its performance level and cost is a better fit. Thanks for the insight.

Does the memory capacity requirement reduce with an increase in the bus bandwidth, which I understand has doubled?

I'm also curious to hear about the vram compression I read about.  Something about being able to compress it down so it would actually use less vram than in the past.  I'm going 3090 for sure.  but I'm still curious

 

@Rob_Ainscough What are your thoughts on FE vs AIB?

answer is go for 3090 as a safe bet

next year we will probably see 3090 TI and the Super Editions.

I found it strange they only put 8GB in the 3080. The 2060, 2070, & 2080 super all have 8. The 2080 ti has 11.

There is the 3070 also with 8 then the 3080 with only 10 and then a huge jump to 24 with the 3090.

It does not seem right that the 2080 would not have at least 12 or 16 to future proof it a bit.

I'm glad I'm not planning a build now.  Hopefully in a year or so a 2080 with 12gb+ ram will be avaliable for around $800.

They're leaving themselves some room to respond to Big Navi. I think they're sure that the 3090 will not be beaten but possibly the 3080 could be. Once Big Navi specs are released in the next while Nvidia will then produce a 3080 super card that tops Big Navi is my assumption.
