An anonymous reader quotes a report from Ars Technica:Riot's new anti-cheat change could create problems for older PCs if the new anti-cheat change is expanded, notes Ars.The update relies on a BIOS patch to fix a UEFI flaw, and many older motherboards, especially Intel 300-series and AMD AM4 boards, may never receive that update. If Riot flags a system and the manufacturer doesn't provide a patched BIOS, players could be locked out of games despite having otherwise capable hardware.
