So i have this annoying lag problem with the game. Sometimes the game works great for like 2-5 mins then it lags again it mostly lags when i'm in a crowded place or when turning directions fast. Now naturally i tried to see if my GPU is the problem but then on 600x400 with lowest settings works the same as 1920x1080 with max settings so that cant be it. Then i tought the CPU might be the problem but i can't see how as my CPU is much better than the one needed to play the game. I tried some stuff i read on Internet like disabling HDI devices and deactivating anti-virus and stuff but it didnt do the trick for me. I want to mention that Prototype (2009) lagged just the same but somehow i played trough that game rly fast so i didn't care but this one i want to enjoy and the lag is really annoying me. I appreciate any help or hint at all so thank you in advance!
