Hardware-based ray tracing is a promising new technology that has the potential to revolutionize the way we create and experience visual content. By making ray tracing more affordable and accessible, hardware-based ray tracing can enable the creation of more realistic and immersive experiences.

XeSS

Intel XeSS, or Xe Super Sampling, is an upscaling technology that uses artificial intelligence to improve the image quality of games rendered at lower resolutions. It is available on Intel Arc Alchemist graphics cards and can be used to achieve higher frame rates without sacrificing image quality.

XeSS works by first rendering the game at a lower resolution, such as 1080p. The rendered image is then passed to an AI model, which uses machine learning to reconstruct the image at a higher resolution, such as 4K. The reconstructed image is then displayed on the monitor.

XeSS is a more efficient way to achieve higher frame rates than traditional upscaling techniques, such as temporal anti-aliasing (TAA). TAA works by blending multiple frames together to smooth out jagged edges, but it can introduce blur and ghosting artifacts. XeSS, on the other hand, can achieve a similar image quality to TAA without the blur and ghosting artifacts.

XeSS is still under development, but it has already been shown to produce impressive results. In a recent benchmark test, XeSS was able to improve the frame rate of Control by up to 40% while maintaining a similar level of image quality.

Intel XeSS is a promising new technology that has the potential to revolutionize the way we play games. By combining the power of AI with the performance of Intel Arc Alchemist graphics cards, XeSS can deliver stunning visuals at high frame rates.

XeSS is an open-source technology, which means that it can be used by any game developer. This will help to ensure that XeSS support is widely available across a variety of games.

XeSS can be accelerated by the dedicated AI hardware found in Intel Arc Alchemist graphics cards. This will help to improve the performance of XeSS, especially on high-resolution displays.

XeSS can be used to improve the image quality of games rendered at a variety of resolutions. This means that XeSS can be used to improve the performance of games on both high-end and low-end hardware.
