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"

UE4 performance for embedded linux platforms

Hi, Recently I was able to get UE4 sample to compile and run for Linux ARM platform, specifically nvidia's jetson TK1.

Running SunTemple at 1280x720 resolution though the performance tops out at around ~22 fps max.

Profiling using "stat unit" seems to show that it is heavily GPU bound. For example: Frame: 54 ms Game: 5 ms Draw: 27 ms GPU: 54 ms

I'm in the middle of looking into how to optimize this further now but I have several questions maybe someone can help with:

  1. Has anyone else ever done this before ? If so, what kind of perf do you see ? Just as a reference.

  2. I read that the SunTemple demo is geared for mobile platforms so I was hoping to get better perf. Is there some kind of performance configurations that should be turned on when compiling UE4Game intended for mobile platform ? How about settings in GameUserSettings.ini file for SunTemple ?
