For me performance in a spaceship - the only place we could be previously of course - is the same as ever, a vSync'd 60. However, my GPU (GTX 1070) is working harder than before to obtain that. I can sometimes see a slight dip below that (GPU hitting 100% load) just as I lift off the pad before exiting a station. Once outside though, everything is as before, bar the harder-working GPU. Getting out of my ships and wandering around it is initially 60 FPS, with the GPU working moderately. If I enter the concourse area though, my fps starts to drop. It's 60 when I first exit the lift but quickly drops as I approach the windows, to the mid-40's. GPU load hits 100% the moment the FPS begins to drop below 60.
CPU-wise, 3900X FYI, I'm not sure, a few Cores have some work to do, but none of them loaded above 30% based on the fidelity of my reporting tools. CPU doesn't really ramp up any of the Cores other than briefly. 4.2 Ghz on one or two Cores is about as high as it gets, and then only for a moment. It's all about the GPU in my case it seems. I've not bothered to go on foot anywhere other than the concourse, because the poor FPS makes things unplayable. From reading about other people's experiences, things get worse on planets and planetary bases - even on GPU's far better than mine - so I'm avoiding them for the time being.
My settings are default - I tried the delete settings trick, it did nothing for me - at 1920x1200 Full Screen mode. I bumped up Anisotropic Filtering to 16x, which makes zero FPS difference, and ensured Blur was off if they weren't already.
My other system, which I installed my Epic account version of ED on, can run Horizons flawlessly at default settings 1200p. That machine is a 2500k and a GTX 680. Doubt it'd run Odyssey even remotely well in its current state, certainly not at default settings anyway.
Some people seem happy with performance, whether that's because the game hasn't fallen below their vSync so they've not noticed the GPU is working harder, or they really haven't noticed a drop. Good for them if they don't notice it, great for them if there is no drop.
Game needs some work, that's pretty much a given.
Scoob.
