FTX is bad for performance. I bought Australia region, at Brisbane and Canberra airport, the FPS is under 20.....I had all options on. Guess what, you will never get the screen shot quality on their website.
By the way, I am using GtX1070, 4.5G CPU and 24 G ram. Now I will give GEX+UTX a try. My platform is FSX steam with DX10 enabled. REX4 ASN
