Starting point for settings

Not tuned for this device: it's the setup from the tested Arc 140T laptop. Change one thing at a time and report what helps.

  1. Power

    Plug in and pick the device's highest performance mode. Put the mode and wattage in your report.

  2. Driver

    Use a current Intel graphics driver. Our Arc 140T numbers use 32.0.101.9175; report your exact version.

  3. Global-memory routing

    Add EDEN_NX2_GM=11 to nx2_switches.txt next to the emulator, or set it as an environment variable. It is the change behind the measured Arc 140T gain. If a game renders wrongly, remove it first and tell us.

  4. Frame generation

    In the graphics settings, turn on Enable Frame Generation and set Target Frame Rate to 60. Add EDEN_NX2_EXTRAPOLATE=1 for extrapolated frames (motion data is wired up for Ocarina of Time only). Report game fps, not the total with generated frames.

  5. Shaders

    The first visit to an area hitches while shaders compile. Judge smoothness on the second pass.

Have one? Send a report

One report turns this page from a guess into data. Include:

  • Device, CPU, GPU and RAM
  • The full graphics driver version (on Intel, like 32.0.101.9175; on Linux, the Mesa version) and the OS
  • Plugged in or on battery, and the power mode or wattage
  • The emulator build, every setting you changed and every EDEN_NX2_* switch you set (or "none")
  • The game and the exact spot, docked or handheld mode, and a screenshot of the scene
  • Average fps and, if you can, p50 and p99 frame times, measured after the scene settled

Never attach keys, firmware, game files, saves, shader caches, or logs that show your user name or folder paths.

Questions

Can the MSI Claw 8 AI+ run Switch 2 games?

It's untested with Guarana. Its Arc 140V has one third-party report on another build (22–24 fps during gameplay). Try the starting settings and send a report from your Claw.

Which power mode should I use on the Claw 8 AI+?

Start with the highest performance mode, plugged in, and note the wattage in your report. We have no measured recommendation for this device yet.
