Hi Captains, Greetings from sunny Portugal! Flying the NGX has been a pleasant experience so far and the hotfixes seem to have eliminated occasional freezes I experienced. There is an issue that still happens now and then and that is quite annoying: fsx completely pauses for several seconds (around 10) and then everything works again. If I ctrl+enter during the pause, I eventually get to my desktop and see a message displayed stating "Nvidia controller stopped responding and was restarted ". A google search on the subject pointed me to possible hardware issues (power and/or memory issues). My last attempt to address this was to underclock DRAM on the bios to 800Mhz (from the default 1066 Mhz). Only had a test flight after that and everything was fine (where usually I would get the error). I just wonder if anyone else experienced this and would care to share some tips on the subject. My system is not overclocked in any way. Some specs on my system (only the ones I recall, since I am not at home right now):Asus P5P board (flashed with latest firmware)Intel I5Nvidia GTX4606 Gb RAM Sergio SilvaPortugal
