From checking on the Steam version what one of our testers ran into within stealth sections was that the enemies were always on high alert even when not actually seeing Spider-Man during the gameplay at all.
I'm afraid I am unsure if this has happened on both Steam and Disc versions of the game. However, when the fps was lowered to 120 and below the game was absolutely fine without any issue. So as it stands we have limited our fix to go to 120fps for this reason.
If we find out the exact reason for this issue happening then we will likely increase the fps cap on our fix.
