I don’t know, if LoL uses it, but there’s some pretty ridiculous infrastructure in place for DRM, where programs can detect that your entire hardware stack (CPU → GPU → cable → Monitor) hasn’t been tampered with: https://en.wikipedia.org/wiki/High-bandwidth_Digital_Content_Protection
They still can’t detect when you’re filming your monitor, but pretty much everything else…
hdcp is easily defeatable nowadays.
would their new anticheat be able to detect it?
