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"

Best GPU for a large arch-viz project?


We're in the process of creating a large arch-viz project, which consists of thousands and thousands of homes, trees, etc. We just want to know, with so much to be rendered at once from a high-altitude, what is the best GPU to go with? We currently are using GTX 1080Ti... Does Unreal support SLI?

Do Quadro cards provide a better performance for real-time applications?


Product Version: UE 4.16

I would stick with the 11GB 1080Ti. If you can get your workstations to connect over swarm you'll be golden. It's not hard to do. I did it with 2 laptops and its a lot of power, so if you connect swarm over several workstations it should get even the craziest of light builds done quite quick. the GPU is only part of the puzzle though, you need some powerful processors to carry the load. Without going into much detail, some stuff UE throws onto the CPU others on the GPU. If you're doing VR put your money on the GPU, if not then what you have should be more than enough. Also try to utilize LODs. I'm doing Archviz too and i have to keep adjusting those to get some pressure off of the cpu/gpu. Also, try to bake your lighting, dynamic lighting is great but it gets heavy with a lot of meshes to consider.

Very interesting. If I understand the release notes correctly, does that mean that AFR is not enabled by default and I need to contact Nvidia to get it to work?
