Came from nowhere. After install RDP was working just fine until last week. I don't remember doing anything on my system or updating RoyalTSX plugin.
Ok i deleted all plugins in the folder and reinstalled app. No RDP performance is back to normal. One of the plugins caused this issue.
weird. Glad your issue is resolved though!
it just jumped to my mind that you might have had RDP debug logging active which is very CPU intensive as there are huge loads of debug messages logged.
could be. thx anyway
