tau is designed to run quietly in the background with minimal cpu usage. it captures frames at intervals rather than recording full video, so the performance impact is very low even on older machines.
install tau, choose “Sign in to activate”, and sign in with google — tau finds your licence and activates itself. you never have to type a key. your key is also on your account at trytau.app/account if you ever want it, and once a device is activated it keeps working offline.
reach out and i'll help you get it running. if it genuinely can't be fixed, you'll get a full refund.
