Good post, but what plane, airport, time of the day, etc.,etc., are you used in the test???Regards

Hi Juan,As I stated, there are many variables involved.I made the assumption that Scott wanted me to test using one of the 'Learn to Fly' lessons. Student Pilot - Lesson 1: Straight and LevelLocal time: 13:26:39 GMT: 20:26:39Season: SummerWeather: Clear, sunny and no windA/C: Cessna 172SP (FS2k2 stock a/c)Position: 2000' over Puget Sound, Pacific NWRegards,MikeEdit:Further to my reply regarding uninstalling drivers. This is so much easier these days, at least it is with Nvidia's recent driver sets. Each set is provided as an executable file that automatically clears out the existing driver files before installing their replacements. There is no longer any need to formally do an uninstall and then install a standard VGA set before installing the replacement driver set, as was recommended under W98/98SE/ME.I imagine the safest way to do it under XP is to run the replacement driver executable from SAFE MODE. However, rightly or wrongly, I have not needed to do this. Running the replacement driver executable from within XP seems to work just fine. I can confirm this also applies to XP graphic driver sets as supplied by Creative Labs for their cards.Mike
