tag:github.com,2008:https://github.com/intel/xess/releases 2026-07-24T01:03:00Z tag:github.com,2008:Repository/504681766/v3.0.2 2026-07-24T18:24:17Z <p>This release updates XeLL to 1.3.2.10 and brings the following improvements:</p> <ul> <li>Fix for <code>xellGetSleepMode</code> returning incorrect value for <code>minimumIntervalUs</code>: previously the value was reported in nanoseconds</li> <li>Fix for a memory leak on non-Intel GPUs, which can be triggered when the application stops calling <code>Present</code> while still using XeLL and recording markers</li> <li>Better Streamline compatibility: XeLL will automatically unwrap Streamline proxy passed to <code>xellD3D12CreateContext</code>, previously this would have lead to a crash later during the session</li> </ul> <div

XeSS-FG:</p> <ul> <li>Fix crash when input resources are using <code>D3D12_RESOURCE_FLAG_USE_TIGHT_ALIGNMENT</code> flag</li> <li>Fix frame rate limit being erroneously lowered after a call to <code>ResizeBuffers</code> or <code>xefgSwapChainSetNumInterpolatedFrames</code> when running with XeLL frame limiter or vertical synchronization enabled</li> </ul> <p>We recommend everyone to upgrade to this version to benefit from the stability improvements.</p> xess-intel tag:github.com,2008:Repository/504681766/v3.0.0 2026-03-09T15:00:56Z <p>Building upon XeSS SDK 2.1.1, this release introduces multi-frame generation and improved frame generation models.</p> <h3>What's new</h3> <ul> <li>Added 3x and 4x Multi-Frame Generation for Intel Arc GPUs</li> <li>Improved frame generation models for better UI smoothness on all supported GPUs</li> <li>Added support for external memory heaps for sharing GPU memory with other game engine components</li> </ul> <hr> <p><strong>Updating from the previous version requires minimal effort:</strong></p> <ul> <li>Replace <code>libxess.dll</code>, <code>libxell.dll</code>, and <code>libxess_fg.dll</code></li> <li>Update game settings UI to choose the number of generated frames instead of ON/OFF toggle</li> </ul> xess-intel tag:github.com,2008:Repository/504681766/v2.1.1 2025-11-13T01:08:07Z <h2>What's Changed</h2> <p>This release adds XeSS-FG
