Due to the unpredictable nature of hardware components (e.g., CPU, GPU, RAM) when overclocked, Runic Games cannot support or troubleshoot computer systems running these configurations.
While it may be possible to launch and run games from the Torchlight series on an overclocked machine, it is possible that you will encounter various unexpected behaviors. In particular, crashes or system freezes — things that are not resolved by the usual troubleshooting steps (e.g., performing driver updates, removing mods, or removing corrupted game saves).
Some manufacturers sell factory overclocked graphics cards. For these, it is recommended that you consider resetting your card to conform to the standard clock rate for your GPU. Check with your manufacturer for further details.
Another important item of note is that overclocking can cause permanent damage to hardware components. This means that, even after clock speeds are returned to normal, issues may persist.
