Core Ultra 200H laptops (Arrow Lake-H)

Switch 2 emulation on Intel Arc 140T

Arc 140T is the only GPU Guarana has measured so far. Every number on this site comes from one laptop with a Core Ultra 9 285H, Arc 140T and Intel driver 32.0.101.9175.

Tested Measured by the maintainers on this build.

What we know

  • Global-memory routing fix (EDEN_NX2_GM=11), frame generation off: 14.75 → 22.83 game fps in Hyrule Field, The Legend of Zelda: Ocarina of Time. The foliage draw fell from 15.7 to 5.8 ms of GPU time.
  • Play configuration with frame generation on: the previous build ran at 19.6 game fps and v20 at about 26.7. They were measured at different spots, so they are not an A/B comparison.
  • One laptop and one scene. Laptops with other power limits or memory will land elsewhere, so send a report either way.

Specs that matter for emulation

GPU architecture
Xe-LPG+ (Arrow Lake-H integrated graphics, with XMX matrix engines)
GPU size
8 Xe-cores, up to 2.35 GHz on the Core Ultra 9 285H
Memory
No dedicated video memory: shares system RAM (dual-channel DDR5-6400 or LPDDR5X-8400, depending on the laptop)
Power
Core Ultra 9 285H: 45 W base, up to 115 W turbo. Each laptop sets its own sustained limit.
Found in
Laptops with Core Ultra 200H processors that list Arc 140T graphics, such as the Core Ultra 9 285H
Driver
Intel graphics driver for Windows; our numbers use 32.0.101.9175

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

Starting point for settings

These are the settings behind our Arc 140T numbers: EDEN_NX2_GM=11 for the verified row, plus frame generation for the play configuration.

  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

  • A fix for an Intel driver cache race is in progress.

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 Intel Arc 140T run Switch 2 games with Guarana?

It runs Ocarina of Time in our tests: with the global-memory routing fix, Hyrule Field went from 14.75 to 22.83 game fps on a Core Ultra 9 285H laptop (driver 32.0.101.9175, frame generation off). That is one laptop and one scene; other games haven't been measured.

Which driver should I use on Arc 140T?

Our numbers use Intel driver 32.0.101.9175. Other versions may behave differently, so put your exact driver version in any report.

Does frame generation work on Arc 140T?

Yes, in Ocarina of Time. Frames are extrapolated from the game's motion vectors, so no latency is added, and our play configuration runs it with a 60 fps target. We report game fps, which doesn't count generated frames.
