Unreal Engine 5 Announced + PS5 Demo

You are missing the point entirely, no one is questioning whether the UE5 engine will be scalable and run across multiple platforms. They even mentioned cell phones would be able to run a version of it. So, can it be run on PC, etc? Yes! Will it run the same as it did on PS5? No! Why? The SSD and massive I/O speeds they have access to stream such high resolution assets which can't be done on other hardware.

The only relevant point here is that some people extrapolated the video running off some laptop in China, to that meaning the demo was running off of that laptop. Even more, using that as a proof it was somehow running better than on the PS5, when Tim Sweeney confirmed it was the video of the PS5 output :D. That's just priceless in of itself.

And yeah, for PC games, surely we'll need to forget running certain games off the HDD, they simply will not be playable there if they are made to take advantage of what we've seen on the UE5 demo. PC gpus are definitely not going to be the bottleneck in any way shape or form, the I/O will be.

Actually I am not missing the point at all.  The presenter interpretations stated it can run just fine without the PS5 GOD tier SSD.  As I asked earlier, are we questioning the statement made by the presenter who works for Epic or just the playback of the demo.

As to your second paragraph, that tweet from Tim only seem to point to the presentation of the demo shone not the words from the presenter translations.  There isn't enough info in that tweet to infer anything beyond that.  

I actually doubt the I/O will be a big problem for PCs because an increase in RAM would be a better solution.  THe key for consoles is that they have limited ram, no expandability and thus fixed which means they are more dependent on SDD solution then a PC probably 3 years from now.

Maybe you should look at the original presentation once again and hear it straight from the man himself, the engine is scalable across multiple platforms, including mobiles. So obviously, it will run "just fine", but what just fine means is what's being discussed here. Instead of streaming 8k textures, would 4k be fine? would 2k be fine? Would we offset the lower resolution with DLSS? Concessions will be made to run best at whatever available hardware you have.

I think it's pretty disingenuous to assume throwing more RAM would be a good solution to the problem. PCs are not limited necessarily by costs, so you'll always have the option to brute force your way out of most issues. There's no way you'll have all the in game assets stored on RAM, especially when we're talking big open world games available to use at any time, especially when these assets are extremely high quality (like the ones the demo was pulling). A game that would allow some sort of high speed moving through the game world would still need to have very fast I/O to populate the world without loading times and pop-in.

Most times the simplest answer is just the correct one, some games will require a mandatory high speed drive, otherwise they just won't be playable, period (or playable with a massive performance hit).
