Intel XeSS-FG for everyone (including Meteor Lake)
Intel Frame Generation is part of the XeSS framework for performance-improving technologies, alongside upscaling and low-latency components. Worth noting that the latter is essentially a supporting tech for Frame Generation because it adds latency.
Previously, Intel mentioned that Frame Generation would only work on Intel GPU architectures with XMX support (Xe Matrix Extensions). Those were featured in discrete architectures (Alchemist and Battlemage) but were also included in Arrow Lake Arc 100T series and in Lunar Lake Arc 100T iGPUs. However, they were not added to Meteor Lake iGPU series.
It looks like Intel has just dropped the XMX requirement , and Meteor Lake will now support XeSS-FG , presumably through DP4a instructions, which are used by 3rd party GPU architectures (XeSS-FG also works on non-Intel GPUs).

According to the changelog posted on the Intel XeSS SDK page, the company has now enabled XeSS-FG support for Meteor Lake architecture. FG stands for Frame Generation, which means that this architecture, which technically does not support XMX acceleration, also supports this technology.

If we look at the developer guide updates, we can clearly see that Intel removed the XMX requirement, specifically listed all Arc-based graphics architectures, and clarified that XeSS also works on non-Intel GPUs.
Frame Generation on Meteor Lake should offer similar performance and quality to non-Intel GPU architectures. Perhaps this change was required since Intel merged all Arc-based graphics into one driver release and maintenance will now be simpler.
Interestingly, it is not mentioned if previous GPU architectures (prior to Xe-LPG) support Frame Generation. We will see once the latest SDK is implemented in actual games.
