Live data not refreshing fast enough 1st gen verus

Got a 1st gen verus same as the one Paul used for years. Having trouble with live data not refreshing very fast. I know it's an old tool but still, its unusable at this point. Any help is appreciated

Only load the pids you need to monitor

Doesn't make a difference. I'm not sure what's wrong.

have you tried it on multiple vehicles? most older vehicles dont have high speed network , how much of a lag is there? if you snap the throttle are you not catching it at all?

Yeah it's ridiculous slow. I can snap the throttle and it will take seconds to update. Like 3 or 4 seconds this is with only one pid on screen. Tried it on 3 different vehicles so far one 2001 and the other 2011.
