RTX 4060 runs on Windows on Arm via RTX Spark drivers, but gaming performance needs work

A developer going by VoidTech has got an RTX 4060 running on Windows on Arm using a driver derived from Nvidia's RTX Spark laptop driver — specifically driver version 590, which predates the current 610.74 release. The setup was documented on Chinese platform Bilibili and spotted by Windows Latest, and while it works, the performance numbers make clear this is still very much a proof of concept.

The Black Myth: Wukong benchmark is the clearest data point available: VoidTech's rig averaged 21 fps at 1080p on medium settings with DLSS set to AA only and ray tracing off. For comparison, PC Gamer's own RTX 4060 testing on a standard Windows install hit 50 fps on High settings with TSR for AA — more than double the frame rate at higher quality settings. Part of that gap comes down to hardware: the host machine is a Huawei Kunpeng 920, a server-oriented Arm processor that was never designed with gaming workloads in mind. These are also unofficial, community-built drivers, not something Nvidia has shipped or validated.

The reason any of this is possible at all traces back to Nvidia's RTX Spark announcement earlier this year — a chip that pairs an Arm CPU core with a proper discrete-class GPU and runs Windows on Arm natively. Getting official Nvidia GPU drivers onto that platform appears to have cracked open a door for other Nvidia cards. Windows on Arm has historically been limited to Snapdragon silicon with integrated Adreno graphics, with no real path to discrete GPU support. Separately, early Qualcomm X Elite dev units reportedly contained PCIe graphics references in their BIOS, suggesting the groundwork for discrete GPU support on Windows on Arm has been quietly sitting there for a while.

Nvidia has promised RTX Spark will hit 100 fps at 1440p in current games when it launches this autumn, and early hands-on time with Alan Wake 2 running on the chip was reportedly smooth. Whether that driver work eventually translates into clean, broad support for existing Nvidia cards on Windows on Arm remains the open question — but it's hard to imagine Nvidia keeping that genie in the bottle once the drivers are out in the wild.
