Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Does a dedicated Server benefit from a high end GPU?

IS THERE a benefit to having a high end GPU installed in the dedicated server box? Does the Dedicated Server utilize the GPU for some of the math and physics areas in the game? Will the server perform better if it has a High end GTX 980 card vs a GTX 240? I am setting up a server for playtesting and was just wondering if this is something I need to think about? Back in 2000 we played Tribes it made No difference or no noticeable difference but perhaps now it might? I have tried searching through the answer hub, I found a lot of useful posts about the Dedicated Server option for multiplayer games but nothing related to this. Not sure where it falls as far a relevancy but I thought I would throw it out there. This is my first Answer Hub post so forgive me if I got it wrong.

Product Version: UE 4.9

Found this post because I have the same question. Hopefully someone can jump in. Do dedicated servers utilize the GPU?

Hi there,

The dedicated server doesn't do any rendering of the game. Instead it handles the game logic on the CPU, therefore it is not necessary to add a high end GPU. You could probably get away with the Intel HD graphics GPU that is built into most of their consumer CPU's so long as your game doesn't perform any of it's logic on the GPU (this would need to be custom coded, most if not all games currently do not, UE4 will not by default) PhysX is run on the CPU in UE4.

If you plan to use the machine for anything other than a server, then it's up to you. Obtaining a better CPU with the money you save will go much further than a GPU as far as performance per dollar goes. A high end i7 or Xeon processor(s) would work the best, the more cores available the better.

Hope that helps!

Thanks for your info, especially that PhysX is run on the CPU in UE4. In our case we're considering whether for dedicated game servers hosted on Amazon Web Services we need a virtual server with graphics capabilities or not. From your information I assume we don't, that's good enough for now!
