I do it often and the system does not become unstable; setting priority to just "above normal" isn't going to harm system stability anyway. Don't take literally the dialog box that pops out when you try to change this setting in the task manager. It can be a problem in some cases and programs at "high" and almost certainly at "realtime", but "above normal" is pretty much 100% safe. And besides, this would be only an option for "advanced users" and would be defaulted to "normal".
Other applications also have this option, like for example some video players, which can prevent occasional stutterings and frame dropouts.
The latency issues I'm talking about are sound cracklings like those which occur when audio buffer is set too low. I have noticed that when many programs are opened at the same time (and probably using some cpu cycles) the "crackling threshold" is lower (crackling occurs at higher asio buffer settings). Increasing a little Pianoteq cpu priority seems to mitigate this issue.
Before you ask me, no, I would prefer to not close each time all my open programs before using Pianoteq.
