Intel XeSS SDK 3.0.2 fixes latency bugs and NVIDIA Streamline crashes

Intel has released XeSS SDK 3.0.2, a software update that improves stability for game developers using the company's rendering tools. This patch matters because it fixes technical bugs that previously caused crashes or memory issues on hardware from other vendors. Developers relying on the Xe Low Latency component can now expect more reliable performance across different GPU architectures.

Stability patch for game developers targeting input lag reduction

The core of this release targets the Xe Low Latency (XeLL) module, which is now updated to version 1.3.2.10. XeLL helps reduce input lag in supported games by managing frame timing more efficiently. The SDK update ensures that this latency-reduction technology works correctly even when developers use rendering frameworks from competitors like NVIDIA.

• XeSS SDK Version: 3.0.2
• Xe Low Latency (XeLL) Version: 1.3.2.10
• XeLL Bug Fix: Fixed xellGetSleepMode returning nanoseconds instead of microseconds
• Memory Leak Fix: Fixed memory leak on non-Intel GPUs when application stops calling Present
• NVIDIA Streamline Compatibility: Automatic unwrapping of Streamline proxy passed to xellD3D12CreateContext

The update addresses a specific bug where the xellGetSleepMode function returned time values in nanoseconds instead of microseconds. This unit mismatch could cause timing errors in applications that rely on precise frame scheduling. Intel also fixed a memory leak that occurred on non-Intel GPUs when an application stopped calling the Present function while XeLL remained active.

XeLL now automatically unwraps NVIDIA Streamline proxies passed to the xellD3D12CreateContext function. This compatibility improvement prevents crashes when developers integrate XeLL with games built using NVIDIA's Streamline framework. The release does not change the XeSS upscaling libraries, focusing entirely on the latency management and compatibility fixes.
