XeSS SDK 3.0.1

This release brings stability improvements for XeSS-FG:

• Fix crash when input resources are using D3D12_RESOURCE_FLAG_USE_TIGHT_ALIGNMENT flag
• Fix frame rate limit being erroneously lowered after a call to ResizeBuffers or xefgSwapChainSetNumInterpolatedFrames when running with XeLL frame limiter or vertical synchronization enabled

We recommend everyone to upgrade to this version to benefit from the stability improvements.

XeSS SDK 3.0.0

Building upon XeSS SDK 2.1.1, this release introduces multi-frame generation and improved frame generation models.

What's new

• Added 3x and 4x Multi-Frame Generation for Intel Arc GPUs
• Improved frame generation models for better UI smoothness on all supported GPUs
• Added support for external memory heaps for sharing GPU memory with other game engine components

---

Updating from the previous version requires minimal effort:

• Replace libxess.dll, libxell.dll, and libxess_fg.dll
• Update game settings UI to choose the number of generated frames instead of ON/OFF toggle

XeSS SDK 2.1.1

What's Changed

This release adds XeSS-FG support for Meteor Lake integrated GPUs and resolves issues reported for 2.1.0:

• XeSS-SR
  • Improves error reporting when creating context on very old drivers
