If you get it on PS4 it's guaranteed to run although a number of PS4 players have had crashed to the home screen.
I wanted to wait for the PC release as though would be a better experience but not convinced at the moment, chilling on the sofa with a big TV from a distance would likely show less of the graphical imperfections. Can look very nice in certain situations but has been designed with console as the priority and this shows in many situations, the awkward inventory for example. Tempted to pick it up second hand on PS4, am sure there will be a lot of copies floating around.
You can unlock the 30FPS cap, I'm getting 60-70 outside according to FRAPS when walking around but doesn't feel that high, not getting terrible stuttering but it does happen, in space stations it drops to about 30. I'm on a fairly old CPU (i2500k) and a 390 but getting better performance than many people with higher specs, not had a single crash yet.
Lot of people moaning about not being able to alt+tab in and out, this is true but if you open task manager and bring to front it resumes the game no problem.
Make sure you check the minimum specs, update your graphics card drivers and have the latest VC++ redist.
I'm enjoying the game but £40 is too expensive, unless you're desperate to try it out I'd wait for a price cut in the near future. It feels like an early access game that's 6 months from launch.
