I have a powerful GPU and CPU. No matter if my graphical settings are at highest or lowest these cracks happend everytime I do a sudden move, like just pressing the "D" to turn right. This is a legal game copy, nothing pirated. I tried to reinstall the game, patch the game, update drivers, check for malicious software, reinstall the Microsoft C++ program thingy and it is still there. This is not a lack of GPU MHz problem, so don't tell me to lower my settings or upgrade my GPU or something, because that is not my problem. I have NVIDIA GeForce 640m with NVIDIA Optimus Technology working with the Intel HD 4000 Graphics GPU integrated in the CPU.
