Try deleting your Nvidia Profile for TrackIr if you have one, don't create a new one and give it a try. I was suffering from some sort of juddering with TIR, deleting the profile from both Nvidia Control Panel and Nvidia Inspector did the trick.
Sure, it was a good sim...for is time. better to go with FC3 instead:

Not sure about your problem, maybe related to your ATI card. You can wait a sale to afford it.

FC2 isn't supported since a long time, better to go with DCS World, the base is free, and you have 2 free aircrafts: Su25T and TF-51D...and you have some nice textures for the Caucasus...

One other problem i've noticed yesterday, the "hear like an helmet"(or something like that in english, my menu is in french) option don't work anymore. Only solution i've found: untick the option>close game>launch game>tick "hear like an helmet" option>closegame>launch>choose Su25T>then choose Mirage, it work :glare: Don't know if it's Razbam or ED related.
A noter également que les trainers servent de base pour l'implémentation de nouvelles fonctions, comme le multicrew avec le L39, qui est profitable pour la Gazelle et le futur F14...
Yes, i've solved this issue by setting adaptative V-Sync ON and 1/2 refresh rate with Nvidia Inspector, constant and stutter free 30 FPS absolutely all the time, at relative high settings in options. Combined with Nvidia DSR, it's a pure joy....
