    Using 16.5 and the latest Win10 ARM build.
    - MS Office 2016 works flawless
    - Steam works
    - Skyrim works like a charm
    - Wizardry 8 works ;-)
    But when trying to play Valheim or Empyrion, the graphics have a problem. Depending on the distance to an object, it is blended in and out (not shown at all)
    although the collision detection still works. Reproducable in Valheim: just hit PLAY and see the camera moving towards the campfire with your character. The trees then flicker.
    I have a feeling that fixing this behaviour isn't a biggie... so perhaps some driver programmer might want to look into this.

    Playing Windows Games with the new M1 chip and Parallels Desktop is wonderful!

    Keep up the good work!
    Kind regards

    Thanks for the suggestions. No compatibility setting helps.

    icetear, try the following. It fixes Valheim and other games so it might help with Wizardry 8 too. Please let us know:
    1. Shut down virtual machine
    2. Click on Control Center, go to the virtual machine settings and then click "Hardware > Boot Order > Advanced Settings > Boot flags"
    3. Paste the following text in the "Boot flags" field: video.untrimmed_dynamic_cbuffers=1
    4. Run the game

    Sorry - I mean it might help with Empyrion.

    Hello SiB,
    thank you very much for your suggestion. That did the trick!
    Both Empyrion and Valheim can now be played. Of course only on low settings - but for some grinding it's perfect! :)
    Still can't believe this is possible on my M1 MBA...

    Kind regards

  6. For Valheim, the `video.untrimmed_dynamic_cbuffers=1` does indeed seem to help! Can anyone explain why? What does that flag do?

    Hello, I try to run Wizardry 8 on my MacBook M1 Max Parallels 18. Windows 11.
    I've got an error "Video devices does not support video resolution"
