Can I Run Serious Sam 3?
Released in 2011, Serious Sam 3 is an action indie game built by Croteam. Publishing duties went to Devolver Digital. It offers a single player campaign and cooperative play. Split screen on one PC is supported, a feature most releases have quietly dropped. Progress follows the account through Steam Cloud rather than sitting on one disk. Builds exist for macOS and Linux as well as Windows. Completionists have 62 achievements to work through. Steam Workshop support means community content is part of the picture, and a heavy mod load can push the real requirements past anything the publisher lists. Steam lists support for 9 languages. Over 21 thousand players have left a Steam review, so this is a title whose performance is widely reported. A gamepad works without remapping, since controller support is complete. Metacritic places it at 72. It is old enough that no current GPU generation existed when it shipped, so modern hardware tends to be far past what it can use.
