Bergey hinted at what seems to be the crux of the matter and the crux of the future for PC gaming on Arm, if there is to be such a future:
"I think that generally, there's becoming more and more value for game developers to be, I guess, instruction set agnostic … As there becomes more of these kind of cross platform [integrations, eg, between Android and Chrome], it's going to become more and more important or interesting to developers say, you know, of course, we'll do an Arm build as well as our x86 build."
I pressed Bergey a little on this, and he explained what this might look like moving forward:
"I think what happens is that developers just say, 'I'm going to go support the arm ecosystem and the x86 ecosystem,' right? I don't think that they're going to have to do this kind of like, pick one, right? I think what you'll just see is developers say, Hey, I'm just going to go support both.
"And of course, there's extra work, and of course, there's going to need to be some industry incentive and stuff to make that happen. But that's the same thing with, you know, supporting an AMD graphics card and an Nvidia graphics card, right? … But at the end of the day, it's in the game developer's best interest to support [both]."
In other words, then, it looks like Arm sees the solution to Windows on Arm gaming compatibility to be in the hands of game developers choosing to make that choice to build in native Arm support.
