Sure! I don't see fps drops either using the AG radar, only during the lights test.
GTX 1080 Ti, 16 GB DDR4, Ryzen 7 2700x, 1 TB EVO 970 SSD
However, generally speaking, I can say that fps are worse compared to the Hornet or F-14 for example. Now that the newest DCS beta has worse performance overall, it is more noticeable.
My DCS settings are highest except motion blur off, MSAA 4x at 1440p, flat shadows, grass to half, tree vis 80%, preload half, smoke density 5, visib range one below ultra, cockpit displays 512, lens effect off, SSAA off and the newest setting is off as well, no idea how it is called - sorry.
