Tried the February drives and the game ran worse. My new card will be here tomorrow so we will find out if it my 560ti or something else.
I'm leaning towards something else.
My Card is a Nivdia, 440GT and I have it maxed with no problems, running the beta driver I talked about a few days ago.
That 560ti should smoke this game big time.
Maybe your CPU is a bottle neck, or maybe a heat issue or the chip set drivers not being updated. Could be a Power issue, maybe the PS isn't giving you the wattage or voltage required or it isn't "clean" voltage, as in the outlet you have it plugged into is not a good connection.
Hell, it could be heat or a funky memory stick.
Honestly, I think you pissed off some old Gypsy woman and you best be doing something about it.
