Intel Lunar Lake CPUs with Battlemage iGPUs have acquired help for a brand new characteristic often called CMRR (Content material Match Refresh Price) in Linux.
Intel’s New CMRR Characteristic For Subsequent-Gen Lunar Lake CPUs Anticipated to Improve The Gaming Expertise
Increasing on what CMRR truly is, it has an utility just like what different applied sciences similar to VRR provide, however Intel says that the best way CMRR works is completely different from the others. The most recent Linux patches by Staff Blue reveal that CMRR is predicted to be built-in into Lunar Lake’s graphics driver, which will probably be leveraged by the Xe2 structure. Right here is how CMRR is described by Intel’s new Linux patches:
CMRR is a show characteristic that makes use of adaptive sync framework to differ Vtotal barely to match the content material charge precisely with out body drops. This characteristic is a variation of VRR the place it varies Vtotal barely (between further 0 and 1 Vtotal scanlines) to match content material charge precisely with out body drops utilizing the adaptive sync framework.

The attention-grabbing half is but to be, about how CMRR will work in a approach to profit these utilizing Intel’s next-gen iGPUs. For Lunar Lake, Intel will probably be including its model new Battlemage “Xe2” structure which is predicted to convey a variety of latest applied sciences and increase upon these supplied by the upcoming Arc Alchemist iGPUs featured on Meteor Lake & Arrow Lake CPUs. These next-gen CPUs are anticipated to reach in 2025.
Nevertheless, an necessary issue to notice is that CMRR is presently enabled with Intel show model 20, therefore no current-gen {hardware} can help it as of proper now. This may trace that Intel could make the characteristic unique to future lineups, or the corporate initially desires to experiment with it with high-end gear.
The inclusion of CMRR in Intel’s arsenal of software program sources is a good transfer because it reveals that the corporate continues to be dedicated to delivering early enablement for help Furthermore, the latest developments by Staff Blue by way of delivering early next-gen help at Linux are fairly thrilling to see as nicely.
