What we know

  • Untested. Send a report: yours would be the first.

Specs that matter for emulation

GPU architecture
Xe-LPG (no XMX matrix engines)
GPU size
Up to 8 Xe-cores (7 on Core Ultra 5 H models), up to 2.25 GHz on the Core Ultra 7 155H
Memory
Shares system RAM. Intel uses the Arc name only with dual-channel memory of at least 16 GB; otherwise the GPU shows up as Intel Graphics.
Power
H-series: 28 W base on the Core Ultra 7 155H, up to 115 W turbo; laptops set their own limits
Found in
Core Ultra 5, 7 and 9 H laptops (Series 1); the MSI Claw A1M handheld
Driver
Intel graphics driver for Windows

From Intel, AMD and device makers' published specs. Power limits vary with model, firmware and mode.

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

  • Xe-LPG is the predecessor of the tested Arc 140T's Xe-LPG+. Results from the 140T don't carry over automatically.

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

Will Guarana run on a Core Ultra 7 155H laptop?

It's untested. Its Arc iGPU (Xe-LPG) is the predecessor of the tested Arc 140T. Try the starting settings and send a report.

Why does my laptop show Intel Graphics instead of Intel Arc?

Intel uses the Arc name only when the laptop has dual-channel memory of at least 16 GB. With single-channel memory, the GPU also gets less memory bandwidth.
