 # avoid breakage in newer CPU ISAs, supporting SSE2 should be enough for
 # 32-bit platforms
+# for special use cases (like running Archlinux32 on 64-bit hardware)
+# we can support up to SSE4.2 (everything above is too hard to fix).
+# As Embree chooses the ISA at runtime, this is no problem for machines
+# not having SSE4.2
