+    If your x86_64 CPU does not support SSE4.2, you can still run the 32-bit Godot
+    executable which only has a SSE2 requirement (all x86_64 CPUs support SSE2).
+
     While supported on Linux, we have no official minimum requirements for running on
     rv64 (RISC-V), ppc64 & ppc32 (PowerPC), and loongarch64. In addition you must
     compile the editor for that platform (as well as export templates) yourself,
