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"

Where should I invest the most for UE4? GPU, CPU or RAM?

I've seen quite a few people ask about specs, however those are dated 2015 or before. It's been such a long time since I've been involved in game design of any kind (circa 2007) so in trying to get back into development as a level designer, I'm trying to figure out where I should invest the most in building my DevBox, specifically for UE4.

Product Version: UE 4.13

For me the first is the GPU, after the CPU AND the memory.

I can tell you a long texte with specification but to be more quicker when I work on project in UE4, I see my GPU begin hot and work a lot of time ;-)

(sorry for my english)

I would recommend you to invest in CPU. Either when you compiling ~7k shaders for new map, or when you are building lightmap for a few hours, your CPU will be used in 100%.

Both of those things are bottle necked by RAM not CPU

UE4 editor is very RAM hungry so don't save on RAM, 8 GB is absolute minimum, 16GB works fine for me so far but i didn't work on nay high end stuff yet on my new PC so i don't know, i know Kite demo is RAM black hole. GPU and CPU depends on what you planing to do, but if you plan to do anything highend, the better CPU and GPU the more you can do. Note that more cores actually improves processing speeds in game development, like code compilation and lightmap shader building. VR are known to require beefier GPU to handle stereo rendering with high frame rate.
