Hi Rick310,
I wouldn't worry about getting to XP12 anytime soon. It really isn't worth the trouble. I bought it on Steam because there was big discount. But I'm not using it. I still fly XP11. IMHO, LR messed up this release with the Early Access nonsense last September. When they released XP12 in December, there were so many issues with it. Many plugins & aircraft just don't work. And that magenta issue hasn't gone away at all. On top of this, LR changed so many datarefs that the Log.txt is full of messages about needing to change them. Even simple FlywithLua plugin scripts are getting quarantined. Now barely 2 months in, LR are busy releasing fixes, the latest being .04. There's a long way to go before XP12 settles down. I prefer to spend my time flying rather than pore over Log.txt file to see why XP12 has crashed...again. So I too am sticking to XP11 for now.
On top of this, LR is being badly damaged by the trolls....read "community leaders" in the other place. But since LR is not affiliated in anyway with these fora, they can't & won't do anything about it.
Happy flying!
PS: I have an i7-4790K, 32 Gb RAM & GTX Titan X (12 GB). 40 fps+ most of the time in XP11. It easily runs XP12.
