It's still a sample size of one game, which is also the first of its kind. Maybe a few years from now we will be a little wiser. On paper, it seems like an attractive feature for open world games, so there is a potential market for it. That being said, it's another question how strict requirements studios would dare to place on it. There are a whole lot of choices in the NVMe SSD market. Even if studios don't want to go with the lousiest, cheapest drive available, perhaps a decent PCIe 3 speed will be chosen, instead of demanding for more for smooth gameplay.

told you.
only difference you'll get from a pcie4/5 is 1. mobo price 2.drive price 3. synthetic sequential bandwidth numbers.
loading will still depend on nand and controller,even with Direct Storage.
I bet with newer nand sometime in the future, upcoming budget pcie3 drives will load faster than those 11GB/s early pcie5 ones.
By all means, people can keep buying those ridiculously priced mobos and ssds with fans to run CDM..... None for me, thanks.

Well, for future reference, that's good to know and my wallet can stop fretting now . 🙂

The main point is finally being able to utilize the "GB/s" of NVME vs the "MB/s" of SATA. For now, it shouldn't matter too much how many GB/s you have, as long as you are in the GB/s ballpark.
I suspect PCIe 4/5 will start making a difference once there's games out there that have DS as a requirement instead of a recommendation?

Speeds might be bottlenecked by the CPU

bottlenecked by 7700X ? ridiculous assumption.
and nand speed matters a lot. SN570,which is 112l bics5 on pcie3 loads games faster than sabrent rocket pcie4 w. 96l bics4.

you're being taken for a ride with pcie5 nvmes, just like early pcie4 nvme/x570 adopters.
don't buy drives because of the interface, the technology on the drive is the same, it's only the connector that's changed.

I don't understand, am I retarded? Isn't the Gen4/Gen5 SSD 25% faster here? Where's the "as fast as" coming from?

You get a 2tb gen 3 SSD for 120 euros or so and a gen 5 for 250 (roughly) how much 3 seconds are with to you ? 😛
I said that in the past for now even a decent mid range gen 3 drive seams more than enough and when direct storage becomes common place in a year or two you will have the whole picture plus ssds will be much cheaper! There is absolutely no reason to fork money now to be ready for the chance of utilizing it in the future .

8200 pro is 64l micron tlc, far from the fastest available. it was great 2-3 years ago, now the standard is 176l.
990 Pro is the latest on the other hand.
It's not just pcie being compared here, 990 Pro has other advantages.

when people were trying to liquid cool their Raptors and show them this post where we go "eh 3 seconds, who cares, basically the same" they'd be appalled. I want that scene back, this one is boring.
Yeah I completely disagree, is 95 and 105FPS the same thing? If I put you in front of them, would you be able to consistently tell the difference? Seriously doubt it. But would you rather have the 95 or 105FPS video card? Would you say they "Perform the same"? No one would, the whole forum exists to stratify tiny differences between an entire range of video cards and CPUs from multiple manufacturers where a difference of a few percentage either way turns a card from useless garbage to amazing value.
I wish I could go back in time schmidtbag
Pretty much what I predicted:
Gen 3 would be fast enough but show signs of being slower.
Gen 5 would have no noteworthy benefit over gen 4.
Relatively speaking, games don't stream that much data from disk, even during a loading screen. I only see DS being useful for real-time loading or when there isn't enough VRAM.

Forspoken isn't really pushing NVMe SSDs to the limit - even Gen3 drives. It's not using GPU decompression. Once games start utilizing GDeflate, we could see a bigger difference between the different generations.
Also, as is stated in the description of the video where the comparison is taken from, there will be faster Gen5 SSDs with faster NAND coming than the one used in this benchmark.
