Gajin. First what came to mind.
Anyways. It would be nice if this issue got looked at while developing that new graphics engine.
I cannot duplicate the error. I have tried with eight different systems and cannot duplicate it. There is no way to fix anything that cannot be duplicated.
That said. I did remove the third party driver/utility War Thunder installs (it stays installed and running even after the game has been removed) as it does interfere with Aces High and there is nothing we can do about that one.
If others are having this problem, we have not heard about it. It would be helpful to get information from them as there might be some commonality we can find.
