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"

Temporal AA kills fps on mobile

Hello everyone. I`ve got a problem and cant find solution anywhere. My mobile game runs smoothly on my device, around 40-50 fps. But after turning mobile HDR and placing post process volume with TemporalAA fps goes arround 4-5. Without AA game looks awful, aliasing is everywhere. Is there any way to make TemporalAA less expensive, or another way of removing aliasing and make models look smoother? I just want to remove awful aliasing (and save as much performance as possible), don`t need any post processing effects.

Thank you in advance!

No, there is not. Temporal AA is not made for mobile devices, and it will not run smoothly for a long time to come.

The real question is: Why do you see so much aliasing on your mobile device in the first place. Most mobile devices have a much higher DPI than the average monitor. Most phones are 1080 and tablets even higher. So aliasing becomes almost invisible at that point.

Everything should look crisp unless you force it to play on a lower resolution.

Hello. I`m sorry, i didnt notice your answer. What are the reasons that can cause such aliasing? The only way to remove it is to set screenpercentage to 200% which also kills fps.
