So, I've recently bought Fallout 3 and began the nostalgia trip (woop!) but I've come across one issue really, where C++ encounters a runtime error while playing the game (usually about 1-2 hours in), and then the game begins to freeze at regular intervals for about 10-15 seconds at a time. Doesn't actually crash or anything, so it's still 'playable', just very frustrating, as this freeze can happen in any situation (i.e. during dialogue, walking about, during combat etc.).

Has anyone else encountered anything like this? Any possible things to try to rectify this?

I've already tried to repair all the redistributable C++ versions in the programs, but error persisted. All other drivers are up to date as far as I am aware.
