Its running in 1080p on an Asus 2k monitor, Graphics where all set to there highest but had to drop a couple down 1 setting after id been building for 4 hours.... Not had to mess with the GFX since that 1st time... I noticed that the Demo maps run without issue on FPS but as soon as you play the 1st proper map then you find out how well your PC is going to play it at your currect settings....
The only thing ive found so far is that when I left click to drag the mouse it stays in its original position instead of following the drag, Not sure if thats intentional or not... It got a little bit low in frames when I nearly run out of food, (Could be a small bug but not sure) but as soon as the storm finished & power turned back on the frame rate instantly jumped back up to full....so 1 small glitch in about 4 hours play... It hasnt crashed or given any other strange behavior...
