Intel has recently unveiled XeSS 2.1, a groundbreaking update that dramatically extends the reach of its frame generation capabilities. Previously, Intel's XeSS upscaling technology had two versions: one optimized for Intel's own Alchemist and Battlemage chips using matrix cores, and another utilizing compute shaders for broader compatibility. With this new release, the frame generation aspect of XeSS, known as XeSS-FG, is now accessible to a much wider audience of gamers, including those who own AMD and Nvidia graphics cards.

The core mechanism behind XeSS-FG, similar to its counterparts from AMD and Nvidia, involves generating intermediary frames to create a smoother visual experience. This process entails rendering two consecutive frames, storing them in VRAM, and then employing compute shaders to interpolate what a frame between them would look like. The minimum requirement for utilizing XeSS-FG is Shader Model 6.4 support, making it compatible with a vast array of modern GPUs, such as AMD's Radeon RX 6000, 7000, and 9000 series, and Nvidia's GeForce RTX 30, 40, and 50 series. This broad compatibility is a major boon for the PC gaming community, offering more pathways to enhance performance, particularly for those without the latest Intel hardware. Although the frame generation routine on Intel Arc cards uses neural networks via matrix cores for interpolation, non-Intel GPUs will default to a compute shader version, which, while potentially leading to subtle visual differences, still promises substantial performance gains.

While the technical integration of multi-vendor XeSS-FG appears straightforward, requiring only minor code adjustments from game developers, the current adoption rate of XeSS 2 in games remains limited, with only 22 titles supporting it according to Intel's official list. Nevertheless, the availability of diverse upscaling and frame generation options is undeniably beneficial for gamers. Having more choices means players are less restricted by their specific hardware vendor, allowing for greater flexibility in optimizing graphic settings. This is particularly valuable for users whose GPUs might not support a vendor-specific frame generation technology, such as GeForce RTX 30 owners who cannot use DLSS FG but can now benefit from Intel's offering. This expansion of options empowers gamers to achieve higher frame rates and a smoother gameplay experience, reinforcing the importance of innovation and collaboration within the hardware and software development landscape.

This development by Intel is a commendable step forward for the gaming community. It not only broadens access to advanced performance-enhancing technologies but also fosters a more inclusive ecosystem where gamers, regardless of their GPU manufacturer, can enjoy improved visual fidelity and fluidity. Such advancements drive the industry forward, encouraging competition and ultimately benefiting the end-user by making cutting-edge features more accessible.
