SSE3 Error

[capjack1234]

Hope someone can help.
Have the ARM64 install of Win 10 running on M1 iMac. Installed the Steam gaming service app and tried to run Witcher 3 and got the error in the attached screen cap, stating my CPU does not support SSE3.

Anybody with a work around for this?

Update to my question... I ran a prog that does a CPU check and it suggests that SSE3 is supported.
Thoughts?

There is a problem with Microsoft's x64 implementation in Windows 10, (much worst tham Rosetta), so no game that requires SSE3 runs. Either you need to install Windows 11 that fixes it, (Witcher 3 runs descent with 30-35 fps at high settings and 1440x900 resolution), or even better get Crossover 21 and run it with 50-60 fps with DXVK enabled.

Is there an ARM preview for Win 11 yet?

If you are on beta or developer channel that's what you update to.
