First off I'd like to say I love the idea of this game. The look and atmosphere I've seen so far are just really superb.
Sadly, the game runs pretty slow for me, I started a new game and once I get about 10km in and more big rocks and other ships show up my frame rate pretty much dips into the 10s
I'm using a Radeon RX 580, which is fairly new-ish. I have an AMD FX-8370 (4 core, 4 ghz). 16 gb RAM. I use two monitors (running the game on one) but tried unplugging one of them and no luck still. Tried running on both monitors at both 60hz and 144hz refresh rates. If there's any other system information or debugging steps that might help I'd be happy to provide.
Maybe the game isn't just that well optimized yet? If that's the case then maybe I'll wait until things are ironed out a bit. I know my CPU may has been around the block a bit and this seems like a *very* physics heavy game :P.
