Yeah, not hard to do better than windows ! ;) I thought freebsd has many improvements each new versions so if your try was many years ago maybe you will find something interesting today… Or maybe not ;) It wasn’t possible to fix the latency because of people who suffered of speech disorder ?
Thanks for your answer ! Someone already mention TPM, I will check about that when I will have free time. Already try pikvm and tinypilot with no success unfortunately… Didn’t know NBSDE, will take a look too !
