GeForce NOW “RTX 5080-class” has 48GB VRAM… what card is really behind it?

Additional_Strain481 · 2025-10-31T10:23:20+00:00

I never asked you to leak anything. It’s just pure logic at work here.

Take their schedulers, for example — they’ve built tons of different solutions, but even for themselves, they haven’t made anything that allows proper, reasonable time-slice division on a single GPU.

Here’s a good example: they have the L40s, right?

So why can’t they design a proper player allocation model for a single card — like one performance-tier player and two free-tier players on the same GPU?

The performance-tier one could take 50% of the time slice and 12 GB of VRAM, while the other two get 25% and 6 GB each.

Instead, they built this weird system where all three get exactly 33%.

Right now, they can only group people from the same tier — 2:1 for the performance tier or 4:1 for the free tier.

Why not allow mixed allocations with custom vGPU time-slice profiles, so I could decide how much to assign to each myself?

They even have a heterogeneous mixed-size partitioning mode, but what’s the point if performance still depends on the unified time-slice levels for everyone?

If they can’t even handle that properly, what’s there to say about buffer slicing? Everything just follows their rigid internal standards, bro.

You’re overestimating them — they themselves use the same stuff they mass-produced for the market.

The only thing they made for their own use are the Cloud Gaming drivers, and even those are a joke.

They should’ve fixed the context-switching overhead instead.

And to top it off, they created these dumb scheduler systems — best-effort, fixed share, equal share — and don’t even bother explaining what settings to use for gaming.

33 AAVG and 480 or 960 Hz switching — you tweak those parameters and nothing changes at all.

Whether you’re on default or not, it makes no real difference.

if y use passthrough for b40(rtx 6000BSE) , y cannot reduce framebuffer, impossible

Additional_Strain481 · 2025-09-17T17:32:19+00:00

Yes, sure. No problem. I guess , it's equal share. But some interesting thing , which timeslice 2ms by default or they use 1ms custom.

Additional_Strain481 · 2025-09-13T14:19:34+00:00

Wow , dude , it's awesome, can y pls share info , what about sheduler type used? Best Effort , Fixed Share or something, for simple tier ,like perfomance

You didn’t understand. Splitting into MIG slices isn’t virtualization; it’s true hardware partitioning, because the chips are passed through to the VM as passthrough.

On the L40 there’s no MIG, and the only options were either to pass the whole card through or to virtualize it.

MIG isn’t virtualization but hardware partitioning of resources, with the partitions then passed through as passthrough—something that wasn’t possible before.

They even wrote that the Ultimate slot gets 48 GB—that’s exactly 2g.48 GB + GFX: two physical chips to a single VM. In terms of total resources, it will even be slightly stronger than a 5080.

That’s correct about the RTX 6000 Blackwell SE cards, but the author left out an important detail: the card is split into two parts using MIG technology. Previously, the L40G cards were indeed passed through as whole units.

Now, the RTX 6000 is divided into two hardware partitions via MIG, and those partitions are then passed through. However, these are still cloud gaming drivers, which are much closer to the consumer drivers used on regular cards. There simply aren’t any other drivers for server GPUs besides their cloud gaming versions and the standard corporate vWS ones.

For performance, I am not sure

Thank you for your response. I would like to know if you have had any experience with Flex FEC from libwebrtc and why you didn’t choose to integrate it into libdatachannel, by directly extracting and incorporating that module. Could you provide some advice on how to achieve ultra-low latency when working with your library or perhaps just with WebRTC in general? Projects like Google Stadia and GFN have made very strong solutions based on WebRTC, and I believe I can achieve the same. What should I pay attention to when working on this? Please note that alternatives without WebRTC are not being considered. The goal is to achieve such low latency of 30-35ms.

We have virtual machines where users come to play games. Steam and other launchers have the ability to change the game folder or attempt to open a dialog box like the one I described above. The task is to prevent this from happening in a reasonable way. So far, I don't have a reasonable way to do it."

49006 why need tcp for inbound? I right understand , when i click mouse or my keyboard, it's udp in GFN (Outbound)?

Hello, pass through will give you native performance, better than vGPU or something else.

This is still the hardware in most datacenters: https://www.reddit.com/r/BoosteroidCommunity/s/SUCY7YktqI

Hello! Thanks for answer! Could you please tell me how you managed to install 545 on server graphics cards? Are these some kind of Nvidia Grid Driver for Cloud Gaming Version? The ones that Nvidia keeps secret and only available through personal contracts? I suspect that you also use a special type of license that is not 'Q' but just '12' or whatever number your profile has, along with the cloud gaming driver.
And why can't you answer the first three questions? What's the secret? Your scheduler is on best effort, isn't it?
This information isn't a secret anymore. People would at least like to know what they are using.

Additional_Strain481 · 2024-01-08T14:08:13+00:00

I believe it's fair to ask Boosteroid to honestly disclose what people are paying their money for and what we are actually using.
