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"

shader complexity breakdown

Hello,

currently im working on a foliage profiling article together with 80.lv I would like to know if I'm right with the following:

alt text

MaxShaderComplexityCount:

  • the lines of shader code to go through every GPU clock tick

  • OR

  • recommended shader units every frame

  • OR

  • just a collection of multiple things (texture sampling/executions/etc.)

The limit is displayed with 2000, but a fully white scene will have a higher count, so its only the visualization maximum, right?

Best wishes!

Nope, neither of 3 is true.

MaxShaderComplexityCount is maximum value of the scale to which shader complexity is mapped. It is set in one of engine's ini files.

Shader complexity view shows accumulated instruction count from all fragments for given pixel.

The view will not allow you to distinguish complexity beyond MaxShaderComplexityCount.
