+Performance Tips
+================
+
+Intel GPUs
+----------
+
+#. Keep the system updated with the latest kernel and Mesa versions.
+#. Ensure SoC firmware is up-to-date. These firmware updates currently
+   require installing the Windows graphics driver; firmware updates
+   via `fwupd` are in progress.
+#. Use Wayland where possible, as it supports additional modifiers for
+   better performance.
+#. For MTL and newer integrated GPUs, disable VT-d if virtualization is
+   not needed.
+#. For discrete GPUs:
+
+   #. Enable `ReBAR`_
+   #. For workloads that keep the GPU busy (e.g. 3D videogames), 
+      minimize idle power consumption by enabling `ASPM`_ powersave mode.
+   #. For "bursty", latency-sensitive workloads (e.g. AI inference),
+      enable ASPM performance mode.
+   #. Enable the 'performance' `cpufreq`_ governor.
