Core Ultra 200V laptops and handhelds (Lunar Lake)

Switch 2 emulation on Intel Arc 140V

Arc 140V is the Xe2 GPU in Lunar Lake laptops and in handhelds like the MSI Claw 8 AI+. We haven't measured it ourselves; one community report exists, on a different build.

What we know

  • Third-party report: 22–24 fps during gameplay on AlfaDev23's build, not on Guarana. We haven't verified it, and it isn't comparable to our Arc 140T rows.
  • No Guarana measurement yet. If you have an Arc 140V device, your report would be the first.

Power
Core Ultra 7 258V: 17 W base, up to 37 W turbo
Found in
Core Ultra 200V laptops; handhelds such as the MSI Claw 8 AI+
Driver
Intel graphics driver for Windows

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.

Notes for this device

  • Arc 140V (Xe2) is a different architecture from the tested Arc 140T (Xe-LPG+). Results from one don't carry over to the other.

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

Does Guarana run on Intel Arc 140V?

We haven't tested it. A third-party report shows 22–24 fps during gameplay on AlfaDev23's build, which is a different build. Send a report with your results on Guarana.

Is Arc 140V faster than Arc 140T for Switch 2 emulation?

We don't know yet. They are different architectures (Xe2 and Xe-LPG+), and we have measured only the 140T.
