SSE3 Error

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.

 

how is going this? sse3 works now or still unavailable?
