Intel releases XeSS 2.0 developer tools, but keeps code under lock and key

Three main components of Intel's XeSS 2 upscaling — Intel

Intel has finally released the XeSS 2.0 Software Development Kit (SDK) to aid game development through upscaling, frame generation, and latency reduction technologies. The SDK is now accessible via Intel’s GitHub repository, providing developers with pre-built tools for integrating XeSS into their projects.

Intel expanded its suite of XeSS technologies last year when it unveiled its budget segment GPUs, the Arc B580 and B570. The XeSS 2.0 SDK introduces three main components: XeSS-SR for AI-driven super resolution, XeSS-FG for frame generation, and XeLL for low-latency improvements. These advancements position XeSS 2.0 as a competitor to Nvidia’s DLSS (Deep Learning Super Sampling) and AMD’s FSR (FidelityFX Super Resolution), offering similar AI-powered enhancements to image quality and performance. Intel has also updated the XeSS inspector tool to support Vulkan and DirectX 11, making it easier for developers to optimize game performance across multiple rendering APIs.

To help with integration, Intel has developed plugins for widely used game engines, including Unreal Engine and Unity. However, despite these efforts to make the SDK more accessible, Intel’s decision to keep XeSS 2.0 closed-source limits its flexibility compared to AMD’s open-source FSR.

As spotted by Tom’s Hardware, the licensing agreement prohibits reverse engineering, decompilation, or disassembly, preventing developers from modifying or extending its capabilities beyond what Intel provides. This approach means that developers must work with pre-compiled binaries, which could impact broader adoption, particularly among studios seeking greater control over their graphics pipelines.

Additionally, XeSS 2.0 remains a Windows-first technology, restricting its immediate availability on other platforms. While Intel has not ruled out future cross-platform support, its current design prioritizes Windows-based gaming environments. The technology has yet to see widespread adoption, with only a handful of titles currently supporting XeSS 2.0. Intel has acknowledged this limitation and is actively working with game developers to expand the presence of XeSS in upcoming releases.

3 things Intel XeSS needs to nail to beat Nvidia DLSS

With features like ray tracing and increasingly complex visuals, graphics cards need a supersampling solution to maintain playable frames. Nvidia pioneered this concept with Deep Learning Super Sampling (DLSS), and Intel's upcoming graphics cards will use a similar feature called XeSS.

In short, XeSS uses machine learning to upscale an image from a smaller internal resolution to a larger external one. DLSS does the same thing, but it requires a recent Nvidia RTX graphics card with dedicated Tensor cores. XeSS doesn't. Instead, Intel is making two versions available -- one that will leverage the dedicated hardware inside its upcoming Arc Alchemist graphics cards, and another that will serve as a general-purpose solution for a wide range of hardware.

XeSS is Intel’s answer to Nvidia DLSS, and it has one big advantage

Intel XeSS quality comparison.

On the heels of the Intel Arc announcement earlier this week, Intel has revealed more details about its upcoming GPUs and the technologies they'll feature -- in particular, XeSS. XeSS is a new supersampling feature on upcoming Intel Arc GPUs, and it looks to combine the best of competing technologies from AMD and Nvidia.

Functionality-wise, XeSS works a lot like Nvidia's Deep Learning Super Sampling (DLSS). It uses a neural network that has been trained on images of a game to reconstruct details from neighboring pixels, and critically, it leverages previous frames to track motion through a scene. This temporal information is what sets DLSS apart, and now it looks to have a competitor in the form of XeSS.

Nvidia’s new rule could help you pick the right gaming laptop. Here’s why

Buying a laptop might seem easy, but if you want the best gaming laptop within your budget, you'll need to dig beyond surface-level information. With that said, every single spec should be readily available so that you know what you're buying, but that has not always been the case.

Fortunately, Nvidia says that it's working with its partners to make sure that one key spec is always listed: The total graphics power (TGP). Here's why it matters.
Why does TGP matter in laptops?
