Sorry for the double post, but I wanted to put this on it's own.
** POSSIBLE FIX FOR THOSE OF US WITH STUTTER/LAG **
I found this tip on youtube and while I initially thought it idiotic as it doesn't make sense, I eventually became desperate and gave it a try. I'm not sure how or why, but it's sorted the game out for myself and a few clanmates who were also having trouble.
* Either wait until the game next crashes, or force close it.
-Start game
-Ctrl + alt + del
-Open task manager
-Find the game process
-Right click and end process
* When asked if you want to start in safe mode, say YES.
* The game will open in a tiny little window, change the resolution to what it should be and hit ESC. (Don't touch any of the other settings)
* Be amazed that it now runs MUCH smoother.
I should mention that if you're one of those who are able to play on max settings with little problem, this likely is not the fix for you.
This is more for those of us who have systems that should be able to play on max settings, but have had to turn settings down to try and make it playable.
(Strangest thing is that my game plays and looks better now than it did at the settings I lowered it to before in order to make it almost playable.)
