I have now installed and uninstalled GSX 3 times, and the result is the same each time. With NO gsx, everything runs like a dream.
Sorry, but it's not possible that GSX could have anything to do with this. Your problem is clearly video memory corruption/exhaustion, and if GSX, just being installed, CANNOT be cause.
The GSX installation doesn't change your FSX settings, except for one: the "Advanced Animations" flag, the installer simply ensure it's being enabled, and that's it. No other changes are made and, more importantly, no changes to your FSX settings are made when uninstalling it, that's why it's not possible the problem would go away just by uninstalling GSX.
In addition to that, GSX doesn't do anything until you call it, and its own code runs entirely outside FSX, and that's why it cannot cause a graphic problem "just" by being installed.
I could understand if you say you have graphic issues AFTER you call a GSX service. Even if this wasn't (of course) a "GSX problem" too, THIS could be possible because, when any 3d objects are being created, if your FSX settings have a problem, or your video card settings have a problem, or if you loaded too many add-ons and/or with too high settings, it IS possible that adding new 3d objects on the active view, can cause graphic issues, which aren't obviously a GSX problem, but rather an indication of a problem you already have with your video/fsx settings/tweaks.
In this case, the first thing to try, is to reset your FSX.CFG to default, by removing it and let FSX rebuild a new one.
Of course, as explained many times already on the forum, if you moved all your FSX installation from a drive to another, it will never work. To correctly move FSX from a drive to another one, the only safe way to do it is to make a real CLEAN uninstall, this way:
- Uninstall ALL your 3rd party add-ons BEFORE uninstalling FSX
- Uninstall the FSX
- Remove the FSX main folder too, to get rid of add-ons without an uninstaller
- Remove the following FSX folders:
%APPDATA%\Microsoft\FSX
%PROGRAMDATA%\Microsoft\FSX
- Reinstall FSX on the new drive. Add all the service packs.
- Reinstall all your add-ons using the proper installers. Installers do many things, like changing files, create default settings, set registry keys, so you should always run an installer, if there's one.
Keep in mind that, if you are very low on space on the Window drive, you will STILL must free some of it, even after you move FSX on another drive, because both the installers and the products themselves will still use the Windows boot drive, so you must always leave it with an healthy reserve of available space.
I changed the subject to be "FSX graphic nightmare", because this doesn't obviously have anything to do with GSX.
