Honestly, I haven't had anywhere near the problems that most of y'all are reporting. I have a modest gaming laptop that seems to run it just fine after I took the time to tweak every setting individually. The things that have a high impact on how things look get set to high, and things that have very little impact on looks (but ironically seem to have the most performance impact) are dialed back or turned off. My last crash was right after SU5 when I forgot to turn off AI traffic right after reading that AI traffic was known to cause crashes.
I'll own that one. The only other hiccup has been getting used to using the new mouse system in the TBM, but once I found the secret, it quickly became second nature. I'm going out for a drink or two in a bit, but I'll be flying tomorrow. If 1.18.15.0 goes as well as 13 and 14, I'll be happy!
