近日，英特尔正式发布了其人工智能驱动的XeSS升级技术。
英特尔XeSS，即英特尔Xe超级采样，它将允许在更高的性能水平下，同时通过硬件加速和创新的AI算法提高图像保真度。
第一个利用XeSS技术的游戏是《古墓丽影：暗影》。
有兴趣的玩家可以从英特尔的GitHub页面下载XeSS 1.0补丁。
这个补丁是在Steam的游戏发行说明中首次被公开，它为兼容DirectX 12（DX12）的系统增加了XeSS支持。
IntelXeSS是GitHub上发布的第二个升级技术，第一个升级技术是来自AMD的FSR 2.0升频技术。
《古墓丽影：暗影》还支持英伟达DLSS技术，因此我们可以比较下这两种超级采样技术的性能表现差异。
该作还支持光追阴影效果，所以开启光追效果时，可以看看XeSS技术能为游戏性能带来多大提升。
Intel has officially released its AI-powered XeSS upscaling technology today before unleashing the company's newest Arc A770 GPU. Intel XeSS, or Intel Xe Super Sampling, will allow for higher performance levels while increasing image fidelity through hardware acceleration and an innovative AI algorithm. The first game title to take advantage of the XeSS technology will be Shadow of the Tomb Raider. Interested players and users can download Intel XeSS 1.0 from the company's GitHub page. The patch, which was first revealed on the Steam release notes for the game, fixes the deprecated online authentication method while adding the XeSS support for systems compatible with DirectX 12 (DX12). Intel XeSS is the second upscaling technology that has been published on GitHub. The first temporal upscaler was from AMD with their FSR 2.0 upscaling technology. On Intel's official XeSS page, Courtney O'Neill, Chief Operating Officer for Hashbane Interactive, introduces the technology in action on their latest game Instinction, which was developed in Unreal Engine 5. The new AI-enhanced upscaler offers an additional 20fps or higher than traditional hardware rendering. The process is explained to provide various upscaling options, such as "ultra quality" modes to higher performance modes, that gamers can take advantage of in their current games. The most significant prerequisite for Intel's XeSS algorithm is graphics drivers with assistance for Shader Model 6.4, allowing the upscaler to be compatible with a comprehensive collection of hardware. Shader Model 6.4 is a new version of the HLSL compiler technology that is demanded in several DirectX 12 features, such as DirectML, DirectX Mesh and Amplification Shaders, and DirectX Raytracing. DirectX's compiler, DXC (or DXIL compiler), is based on LLVM and develops Shader Model 6 programs. Artificial intelligence and machine learning offer the ability to "synthesize images" similar to what is seen from ultra-high resolution rendering by rebuilding subpixel data from the primary pixels and compensating motion from previous frames. The process is accomplished by the neural network specifically trained to produce higher performance levels while also delivering high levels of quality. Additionally, Intel XeSS will support AMD Radeon and NVIDIA GeForce graphics cards, which were tested by CapFrameX using the AMD Radeon RX 6800XT graphics card. The new upscaling technology will also leverage the DP4a and XMX hardware abilities in Intel Xe graphics cards to enhance performance. While the XeSS upscale technology is available, the code has not been offered as an open source option, and it is unknown if and when the company will release the official code. For now, developers will have to manage with the initial SDK and DLL libraries that are currently available. Intel does mention that XeSS upscaling performance will vary by use, configuration, and additional factors. The rendering on the company's official page notes that the demonstration was created by using the Arc A770 GPU and the company's Core i9-12900K CPU at 1440p resolution.
