Common Causes of Stalker 2 Crashes

Understanding why S.T.A.L.K.E.R. 2 might crash or fail to launch is essential. Let’s explore the most frequent causes:

Compatibility Issues

One of the main reasons for crashes is incompatibility between the game and your system. S.T.A.L.K.E.R. 2 is a graphically intensive game, requiring robust hardware to run efficiently. Mismatch in system specifications, especially in CPU, RAM, and GPU, can lead to frequent crashes or launch failures.
