For instance, in a specific Vulkan benchmark of Cyberpunk 2077 at 1080p resolution with medium settings, the Arc B390 has been observed to deliver an average of 55 FPS, while a comparable AMD card in the same test system achieved around 52 FPS. This difference, though seemingly small, can be critical for a fluid gaming experience, especially when targeting higher refresh rates or more demanding visual settings.

Further testing in titles like Shadow of the Tomb Raider, also utilizing Vulkan, has shown the B390 consistently outperforming its AMD rivals by margins of 5-10% in average frame rates. These consistent gains across multiple demanding games suggest that Intel’s driver optimizations are effectively harnessing the B390’s architectural strengths on the Linux platform. The open-source nature of Intel’s drivers allows for rapid iteration and adaptation to the specific demands of these game engines.

DirectX 12 Translation Layer Performance

A key area where Intel has made substantial progress is in its DirectX 12 (DX12) to Vulkan translation layer, known as DXVK. While many Linux games natively support Vulkan, a significant portion of the Windows gaming library still relies on DirectX. DXVK allows these DirectX games to run on Linux by translating their API calls into Vulkan calls, which the Linux graphics drivers can then process efficiently.

Early iterations of DXVK showed varying degrees of success across different hardware. However, Intel’s Arc drivers have been specifically tuned to work harmoniously with DXVK, often yielding superior performance compared to other GPU vendors when running DX12 titles through this translation layer. This is particularly noteworthy as it enables a wider range of games to be playable at higher performance levels on Linux.

In testing games like Grand Theft Auto V through DXVK, the Arc B390 has demonstrated a more stable frame rate and higher average FPS compared to AMD cards in certain configurations. This suggests that Intel’s implementation of the translation layer, or their driver’s interaction with it, provides a more efficient pathway for DX12 commands, minimizing performance overhead.

Driver Maturity and Open-Source Advantages

Intel’s approach to driver development for its Arc GPUs on Linux has been a departure from the traditional vendor models, emphasizing open-source collaboration from the outset.
