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"

Extremely slow performance on a very high end pc, confused.

Hey there unreal team. So in the default viewscreen all runs well, but inside bp editor and in animation and mesh screens I get ~10 second delays, mouse mis-reads, and sometimes assets can't even be moved or repositioned, requiring a restart of unreal.

My hardware is

32gb ram

dual titan x

i7 8 core processor

~1tb SSd

Product Version: UE 4.10

Titan X, 32gb ram, 3.7 quad core

Running the kite demo I get like 10fps. What the fuck is going on here

Unreal doesnt play nice with SLI; if you have that on?

I play on a similar (but slightly worse rig) and don't have many issues.

I didn't have sli on. It's super odd, my rig should handle the editor okay but its nearly not usable. Sometimes I really can;t use it and have to shut the engine down.

Honestly I have no idea; I have a 5960X, 64gb ram and a pair of 290X's (well 290s flashed) and the thing runs fine.

Try a diff gpu driver?
