Snapdragon X Elite laptop runs Cyberpunk 2077 using an RTX 4060 eGPU with the help of an RTX Spark development driver

TweakTown reports that a YouTuber known as Chaowanke has successfully paired an RTX 4060 eGPU to a Snapdragon X Elite laptop using NVIDIA's RTX Spark development driver, achieving playable framerates in Cyberpunk 2077 and Forza Horizon 6. The RTX 4060 was connected via a Razer Thunderbolt 5 dock through the laptop's USB4 port, drawing GPU driver support from NVIDIA's recently released RTX Spark development driver — a native Arm64 GeForce driver package designed for the upcoming RTX Spark platform. The driver reportedly refused to install through the standard installer due to a hardware incompatibility error, but the YouTuber discovered a workaround by extracting the ARM64 driver manually through Device Manager, bypassing NVIDIA's installation wizard and successfully loading the driver on the unsupported Snapdragon X Elite configuration.

In Cyberpunk 2077, the makeshift Arm eGPU configuration achieved approximately 44.6 FPS, while Forza Horizon 6's benchmark registered around 53 FPS — both solid gameplay results for an entirely unsupported hardware combination running through USB4 bandwidth constraints. The feat closely follows a similar effort covered earlier this month, where a Chinese modder known as VoidTech got an RTX 4060 working on a Huawei Kunpeng 920-based Arm workstation using the same RTX Spark development driver. While VoidTech's Kunpeng-based setup was severely CPU-bottlenecked (21-25 FPS in modern titles due to the server-oriented Arm processor), the Snapdragon X Elite's consumer-focused architecture delivered substantially better gaming results — highlighting the gap between repurposed server silicon and purpose-built consumer Arm CPUs. The Chaowanke mod also benefits from the Snapdragon X Elite's integrated Adreno GPU driver stack and USB4 controller, which are designed for consumer laptops rather than enterprise workstations.

For Canadian consumers tracking RTX Spark's development ahead of its Fall 2026 launch, the Snapdragon X Elite eGPU mod is an encouraging sign that NVIDIA's native Arm64 driver ecosystem has real-world utility beyond RTX Spark hardware itself. The fact that an enthusiast could extract functional GPU drivers from the RTX Spark development package and run them on an entirely different Arm platform — a Qualcomm Snapdragon X Elite laptop — suggests that NVIDIA's Arm64 GPU driver architecture is fundamentally sound and capable of supporting modern NVIDIA GPUs across the Arm Windows ecosystem. This has positive implications for Canadian early adopters considering RTX Spark laptops from Microsoft, ASUS, Dell, HP, Lenovo, or MSI: the driver stack that NVIDIA is building for its platform appears to be robust enough to extend beyond its intended hardware, which bodes well for driver maturity, game compatibility, and performance optimization at launch. Canadian readers should note, however, that the eGPU approach — running a desktop RTX 4060 over Thunderbolt 5 — is not representative of the integrated RTX Spark N1X experience, which pairs a custom Grace CPU directly with a Blackwell GPU over NVLink-C2C at 600 GB/s rather than relying on USB4 bandwidth constraints.
