ALLM allows the GPU to signal connected displays to activate 'Game Mode' for reduced latency, triggering automatically when content type is set to 'Game' or when Gaming-VRR is enabled. This follows earlier AMDGPU patches for HDMI 2.1 FRL and Display Stream Compression support. The patches are under review on the mailing list with a tight deadline for inclusion in Linux v7.3, otherwise they may land in v7.4. ## Full article daily.dev links to this article rather than hosting it.
