     Generally no. You should avoid it for old CPUs as it can cause more harm than good.
 
     To give a rough guideline, using game-performance on anything below a 6-core/12-thread CPU will likely not increase or even decrease performance. As with most options, you should test yourself if they improve performance on your specific system or not.
-      - For Intel the approximate cut-off therefore is 8th-gen Coffee Lake for i7 and i9 CPUs and 10th-gen Comet Lake for i5 CPUs.
-      - For AMD it is the 1000 series for Ryzen 7 and Ryzen 9 CPUs. For Ryzen 5 CPUs it's also the 1000 series, but only the Ryzen 5 1600 and above. This is the case until the 5000 series where now all Ryzen 5 CPUs have 6 cores and 12 threads.
+      - For Intel desktop CPUs the approximate cut-off therefore is 8th-gen (Coffee Lake) for i7 and i9 CPUs and 10th-gen (Comet Lake) for i5 CPUs. All Intel Ultra CPUs should work.
+      - For AMD desktop CPUs it's the 1000-series (Zen) for Ryzen 7 and Ryzen 9 CPUs. For Ryzen 5 CPUs it's also the 1000-series, but only the Ryzen 5 1600 and above. This is the case until the 5000-series (Zen 3) where now all Ryzen 5 CPUs have 6 cores and 12 threads.
+      - Intel i3 and Ryzen 3 desktop CPUs never have more than four cores.
+      - Core counts for mobile, workstation and server CPUs are all over the place so research what you have and try out different settings, that's half the fun of owning PC hardware!
