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"

Framerate "stuck" - Graphic settings wont change anything

Hello,

again I have massive performance Problems within the Unreal Engine 4. I have one map that is stuck with low FPS and a very high render time. I currently have 6 large scale maps finished and 5 of them run extremly well with 60-90fps. Another map with the same assets and settings (just other light angle & color) is stuck at ~50FPS and 20ms render time which feels extremly like extrem lag and it's just no fun to play.

I'm using two sided foliage with distance culling and a dynamic directional light. Changing the graphical settings won't change anything relatet on FPS. Even looking on the ground won't increase the FPS like in all other maps.

The Frame lock is set to 120 in this example and I have absolutly no idea what's going wrong here. Even no grass and shadows rendered and the GPU load is extremly high.I already tried Ray Traced Distance Field Soft Shadows but that hat absolutly 0 impact on the performance.

Recreating the map is almost not possible for me, my time scope is extremly tight right now and it's getting extremly frustrating. I btw have still the massive performance problems that I can only use the directional light to cast shadows, all other light sources woud ground the FPs down to <15 but that "would be ok" if I can't fix this now.

Im running with this system: CPU: Intel Xeon E3-1231 v3 GPU: Sapphire R9 290x 4GB RAM: 16GB OS: Windows 10 64bit

I reinstalled the system ~a month ago. I would be very pleased if someone out there would have any tipps for my. There must be something terribly wrong ... Thank you very much.
