The game does not perform poorly in absolute terms on my hardware, but it's so much slower than is should be that hardware that is well within the bounds of the specifications Frontier is listing cannot run the game well at any reasonable settings.
Fully agreed, their
recommended specifications that don't hold up to what they promise
and that are displayed along with the purchasable content on the store pages is exactly what we take issue with.
To be clear, everything below recommended down to and including minimum specs is expected to perform subpar.
But recommended specs and upwards is expected to perform reasonably well. And Frontier even wrote somewhere that it means you can expect 60 FPS on average on recommended specs (note that the term "on average" allows for occasional brief frame rate drops, but it doesn't allow a rate of significantly less than 60 FPS over an extended interval such as 10 seconds, a minute or 5 minutes).
If they advertised it along with much higher recommended specs that can actually handle it at 60 FPS, there would be far less people complaining now.
