I will make a dedicated thread to this once I have better numbers, but honestly the JF-17 performs worse than any other module in DCS!
in VR, yesterday: F-18 free flight held 40 fps steady
JF-17, same settings, struggled to get 27!!
i7 4790, GTX 1080, 32gb of ram, 0.8 pixel density and 128% SteamVR SS. No MSAA, medium-high settings (kept shadows on)
