Comment on Valve is working on a version of proton for ARM devices
Vincente@lemmy.world 2 months agoAnd the second example is Rosetta 2 for gaming on ARM-based Macs, especially in the context of Apple Gaming. You mentioned that some emulators running x86 games are inefficient. That’s the point! emulation is not the same as translation.
Translation is generally more efficient and can sometimes even match or exceed the performance of native execution.

Apple’s M-chips have dedicated hardware to accelerate rosetta 2 (support for x86 memory ordering), please stop using rosetta2 as a show of what x86 on ARM can do, as it is a vertically integrated piece of software that is not indicative of the current market for anyone outside of apple.
Just take a look at windows on those new qualcomn chips - when they do the translation, the performance is underwhelming to say the least.
Yes, it will improve, but it currently does not exist outside of Apple.

It is actually strongly related to Valve because Rosetta 2 or the Game Porting Toolkit are based on the open-source Proton, which was developed by Valve. So, it’s not an Apple-exclusive technology; it’s closely tied to Valve. I believe Valve has the ability and ambition to do the same thing, but better than Apple.

Rosetta and proton are two completely different layers.
Game porting toolkit is indeed also based on wine, but that’s only the conversion of directX to ogpl or vulkan (using metalVK in Apple’s case)
Rosetta is a completely separate harware accelerated (as in, the chips have dedicated hardware for this) translation layer for x86 to ARM
Given the lengths they had to go through to get even this custom APU, I can only imaging the difficulty in procuring a first-gen ARM offering from AMD.
I swear, this is just the “VR is really here, and it’ll replace conventional gaming!” Debate all over again. I’d be surprised if it happens in the next two years. After that? Maybe, if x86 doesn’t catch up more than it already has (which I fully expect it to do).

I never said it will happen in the next two years. I just said that it’s a possible path, and apparently it has no chance of happening in two years. Valve’s next step is apparently to update the Steam Deck 2 with AMD chips. A 5 to 10-year period is what I expect.
I won’t talk about this anymore. Bye
