Sampler feedback is virtual texturing it's been done a decade ago and Microsoft actually calls it prt+ it's fucking the same crap it doesn't increase memory mate.
The ssd on Xbox can't be used as ram that's a marketing lie all it has is a decompression block and api tricks to try and simulate what the ps5 does
there's a lot of hardware bottlenecks that you have to remove that the xbox still suffers from the ps5 has a lot of processors to do that plus fucking 12 channels, and we've seen this in games already the Xbox stutters/ drops frames or freezes as any other machine when streaming data in games like cyberpunk freezes, control drops fps, dirt 5 has texture streaming issues And even the medium the game that's using the ssd and velocity architecture bollocks has texture popin issues that digital foundry found out and none of this problems are seen on ps5. So no mate virtual texturing Ian to going to save xbox and the ssd on xbox isn't anything near to what ps5 Is doing.
We've seen unreal 5 render scenes with 100+ gb of 8k/polygons per pixel something impossible to do without having 100 gb of ram on ps5 infact epic had to remake the engine because of how impressive the ps5 was, we've seen ratchet switch worlds in 2 seconds, we've seen Spider-Man, demon souls, godfall, little big planet all load in a second on ps5 and none of this on Xbox. If the series x ssd was anything special we'd have already seen something and I'm sorry to say it isn't special your being deceived by marketing buzzwords.
