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"

VR low FPS in some "demos"

Hi! I just recived my HTC Vive and has previously had an Oculus DK2 to play around with. However.. I have had some problems getting a good framerate for both the DK2 and the Vive in some Unreal Engine content and thought that I should post my issues here since I might very well be missing something.. Today I tried running the Blueprint Learning demo using my Vive, however.. the framerate was terrible (or somewhere between 40-60fps.. I would like to have at least a solid 70fps to avoid any stuttering).. the strange thing is that I also ran the Showdown VR demo on the very same machine.. and that was very smooth and at a really good framerate.. so.. basically my question is.. might I be missing something?.. is there like an option that should be toggled?.. or is simply the showdown demo so extremly well omptimized for VR compared to the Blueprint Demo? I noticed that the stuttering/"lag" almost always showed up while looking at the tree in that demo.. but I find it hard to be that performance demanding to render that tree compared to the Showdown scene..

any thoughts?

If you press "F5", you can see the shader complexity which has a lot of influence on how much horsepower it takes to render a scene. If it looks mostly red or white, you're probably going to have some rendering and framerate issues within VR.
