From what I read, some folk switched this setting to Medium or High after replacing a GPU
and then ran the Sim, then restarted, after they did that it was supposed to fix the PC, and they could set up the sim as normal.
I did a lot of research on the " Nvidia settings " I can post all 6 jpegs showing my settings if you need them.
I have had no problems running the sim for ages. no CTD, a few stutters because I am on the limit I have 5 settings set to Ultra and get 40fps in the air and 20fps at the airports, and the last update did have a framerate hit, and I have reduced settings to get over this.
