I thought the same, for years I used both MX (mouse + key) with the dongle.
Until recent a few upgrades when I realised that after an hour, logitech processes were using 700-900mb of RAM. every day. up to 1,2Gb after a long day.
I switched to bluetooth on both, it’s down to 50mb after 3h, it won’t go beyond 100mb.
I assume it’s using the standard bluetooth protocols while the dongle needs some extra processes and apps running (logi bolt, the app to manage the dongle would hog 70-80%)
The dongle is at had if needed, it’s been a month, no trouble on the horizon.
That being said, Is it bluetooth only, or does it have a dongle as well ? if so, does it bugs out and stutter too ? (we need to rule out things to find out the actual problem)
you said you did the updates, you’re using logi option or option+ ?
can you try it on a different computer ? and if possible on sketchup 23 as well ?
Again, it’s to pinpoint where it fails, if it’s YOUR machine or if it’s SU22, or your mouse or…
