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"

Can I profile my GPU from inside the editor or another software?

Hello. I have very bad UE4 performance on my PC. Actually I have very poor gpu - AMD FirePro 2270. I set lowest quality in "Quick Settings" menu, turn off all post-processing, set unlit mode and still have 10 fps. Now I'm just curious and want to know what causes so bad behavior. Is there any possibility to profile GPU from inside Unreal Editor? Or what is the best utility for that?

A quick way is to write PROFILEGPU in the console,
a window will pop up showing how long different operations took.

Example:
 (i don't have any issues just showing an example)

1) I write PROFILEGPU while playing
2) A window pops up with multiple coloured bars
3) I click on the biggest bar which directs me to TemporalAA
4) I see it was the AA which took forever, so I change my global (unbinded) postprocess volume to disable AA

Hope it helps!  

Alternatively, write PROFILE when you wish to start recording a session, then write PROFILE again to stop the recording. Once it stopped, the session will be auto-saved to UnrealFrontend, so open your Unreal Frontend and look at the complicated interface. You might want to read some of the documentation on the unreal pages to get started, but if you can't find any good explanations on the tool you might just want to trial-and-error like i did, or wait for Epic to cover the topic in more depth.

Thank you. Sad but PROFILEGPU is not working for me - I simply have empty bars. Session frontend seems good, will investigate.

Someone please correct me if I'm wrong, but I think the Session Frontend profiler is only a CPU profiler, not a GPU profiler.
