A lot of people here seemed excited for these chips. It’ll be very interesting to see the gaming performance as this could bring in an entire new segment of portable devices running Linux if powerful enough to deliver solid battery life and CPU performance.
No, that’s not at all what I said. Translating between CPU architectures and translating API calls isn’t even close to the same thing.
Obviously. Games are compiled for Linux natively. Same can be done for Linux on ARM. Opensource games like Xonotic already do this, proprietary games like War Thunder are compiled for ELBRUS and I’m sure can be compiled for ARM. If Valve wanted, they could release their games compiled for ARM tomorrow.
Porting games to a different architecture is normally quite a bit more involved than just recompiling them, especially when architecture-agnostic code wasn’t a design goal of the original game code. No, Valve couldn’t release all their games natively running on ARM tomorrow, the process would take more time.
But even if Valve were to recompile all their games for ARM, many other studios wouldn’t just because a few gaming handhelds would benefit from it. The market share of these devices wouldn’t be big enough to justify the cost. Very few of the games that run on Steam Deck are actually native Linux versions, studios just rarely bother porting their games over.
I’m not saying ARM chips can’t be faster or otherwise better (more efficient) at running games, but it just doesn’t make sense to release an ARM-based handheld intended for “PC” gaming in the current landscape of games.
Apple can comparatively easily force an architecture transition because they control fhe software and hardware. If Apple decides to only sell RISC-V based Macs tomorrow and abandon ARM, developers for the platform would have to release RISC-V builds of their software because at some point nobody could run their software natively anymore because current Macs would be replaced by RISC-V Macs as time passed by. Valve does not control the full hard- and software stack of the PC market so they’d have a very hard time to try and force such a move. If Valve released an ARM-based gaming handheld, other manufacturers would still continue offering x86-based handhelds with newer and newer CPUs (new x86 hardware is still being developed for the foreseeable future) and instead of Valve forcing developers to port their games to native ARM, they’d probably lose market share to these other handhelds as people would naturally buy the device that runs current games best right now.
In a “perfect world” where all games would natively support ARM right now an ARM-based handheld for PC gaming could obviously work. That simply isn’t the world we live in right now though. Sure we could ramble on about “if this and that”, it’s just not the reality.
