Im running an i9-9900k, GTX 1080, on a 1080p monitor with most of the DCS settings on max.
Supercarrier, in a hornet, daytime, with no other units, singleplayer or multiplayer, I get 30 fps staring at the cockpit. Increases if i look elsewhere, but staring at the cockpit is flat 30. Improves once I depart the carrier.
Supercarrier at night drops to 20-16 fps D:
