Wow this is great news and maybe my next laptop will be based on ARM.

I would wait for X2 and the Nvidia chips for your decision. Honestly the new uarch on the phones are giving me a lot of hope

Yeah, first generation Oryon and Snapdragon X1 are mid.

Microsoft is welcome to set an example and port their own games to Windows on ARM to demonstrate the gaming abilites.

Yeah, having no AVX support meant absolutely awful software compatibility. Yet fans here didn't realize and denied that. This changes a lot even personally to me. I might get one now.

so it wont silently drop AVX512 anymore? Great.

This is really good news and hopefully reigniting the competition from the lackluster launch of Snapdragon X. My fears for the dev kit being canned and slowing down the WoA ecosystem may have hope after all.

This new support in Prism is already in limited use today in the retail version of Windows 11, version 24H2, where it enables the ability to run Adobe Premiere Pro 25 on Arm. Starting with Build 27744, the support is being opened to any x64 application under emulation. You may find some games or creative apps that were blocked due to CPU requirements before will be able to run using Prism on this build of Windows.

Premiere Pro was one of the most critiqued things with reviewer having to use the older versions. Hopefully things are on an uptick for WoA.

Why are people so hung up on the dev kit?

There was no point in launching it after X Elite laptops are already on sale.

This and the developer kit should have been ready and available at launch.

Honestly, QC should just sell 8 Elite mini PCs (or Qualcomm Reference Phones) with Windows on ARM so Devs can work on porting apps and optimise for the new GPU architecture that will be in the X2.

This way Devs could work on making apps that work with Oryon L and M cores well, they can work with Microsoft on bettering the scheduler for these chips and when X2 launches, it would have better ecosystem than the 1st gen had.

This is big news.

AVX emulation finally!

I didn’t know it would happen so soon but pretty obvious Microsoft was working on it. Now we just need better GPUs and drivers in the mobile space

Microsoft Blog Post.

This now means that every x64 app will run with no problems. Only thing that can't be fixed is kernel level anti cheats. It's now a matter of time til compability issues are behind us.

It has this small caveat

>Note that in today’s preview, only x64 applications can use these new CPU features. If you have a 32-bit app or a 64-bit app that uses a 32-bit helper to detect CPU feature support, that app won’t detect the new features in Prism.

But it looks like it won't take long for Microsoft to close the gap here too.
