In space I get about 59 FPS, 58 inside a station/port (70ish near elevator), 59 in hangars, and 43 in ground war (haven't checked for space combat yet). All of it depends on whats happening. An example is that I get considerable drops when coming out of frameshift in space or on planet and then it bumps up again.
I got a 2080TI 11GB VRAM, ryzen 9 3950x 16 core processor overclocked at 4.3ghz and 64GB of ram. I run it on ultra but I turn off bloom and blur. I also run it in 1440p with AMD FidelityFX to supersample at 1.5 to smooth the edges out as much as possible (any higher and the FPS drops considerably and gives the game major delay). From trial and error the other supersampling options don't reduce edges as much as the way I got it set up now.
I really wish antialiasing actually worked good though. Jagged edges with this hardware is strange, even if I have reduced it as much as I possibly can without sacrificing performance.
All in all, I have so much fun that I can't really tell the FPS drops happen except it's a tiny bit noticeable in ground war, but even then barely because I'm so engrossed in the atmosphere of the music and voice chatter.
New commander here in the last few weeks. Loving the game A LOT. xD
