Basically; I bought the dead by daylight cheat not too long ago and the cheats wouldn't stay active or update in real time unless i had the cheat window open. but if i kept the cheat window open it takes up like 40% of the game, but if i hit insert, it will stop updating and basically stop working. I did buy the stream edition. Is it perhaps that i need a second monitor to use properly? I'm interested in buying it again. But im afraid of having a bad user experience such as this again
