They had the exact same problem with X3: Albion Prelude when that first came out, shockingly low FPS for some people, it took them a while to patch the problem out, but they got there in the end, X: Rebirth will be no different.
non of the graphics settings seem to do anything though having them maxed or not I still get the same fps , my cpu load on a haswell is something like
70/80/70/60
load on the cores and that is at 3.99ghz
my 7850 usually sits around 70% gpuload.
some systems I get 60fps , other I get around 20fps , at one point delivering the 100 energy cellls my fps dropped to 12fps whilst I sat waiting the 30mins for my hauler to arrive.
maybe the game is fun once you get the boring stuff out of the way but it seems like it will never end....
why is the map so retard mode? you can't interact with the map , zoom about etc it's just bloody awful so many features were done far better in the previous games.
I'd say the previous games had better visuals and a better art style as well.
I'm not done with it yet though I crashed enough yesterday to know there were 3 patches or more.
sometimes you can play for hours and everything is fine other times crash , crash , crash.
they clearly never QA tested the missions because you have to do them exactly as specified , even the slightest diversion from what the game is expecting ca break the missions and your savegame.
also yesterday another of my savegames got bugged when the console that pops out from between the seats refused to work.
reloading , rebooting etc did nothing that save game was just ruined for no reason.
one thing I did like a lot is the backstory on the devries system or whatever it's called when you get the databurst about their struggle I found that really cool
btw, I feel the game runs better in window mode and you can alt tab pretty safely where as full screen usually an alt-tab for me crashes it
heres an example of how buggy the game is , on the mission where you have to run the portal blockade run it before it tells you just head straight for the gate.
the game will send you back through the portal to do the same thing again because you skipped through before it told you to LOL.......
