    loss in performance using STL's Vector, instead of linked lists?

    I was wondering, what would the performance difference be if you used a vector to hold your constantly modified info, e.g. firing off gun rounds in an FPS, compared with storing and traversing a linked list? Is it really THAT great , now that speed of proccessors has reached this far?

    Use whatever STL container best fits your needs. If you're using a linked list now, chances are an std::list would be better than an std::vector.
    You need to understand each containers limitations (searching, insertion, traversal, deleting, etc.) and choose which one would most efficiently represent your data.

    I doubt you'll see that huge of a performance hit in using an std::list vs. your own linked list which you programmed.
