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"

CPU/GPU power of mobile device detection

Hi all.

How to detect the power of device, especially of android i guess. Because, on one device the game has 16 FPS so it is slow, but on another it has full FPS..

Is there some intelligent way how to detect the power of CPU or GPU, to use some concrete rendering settings?

I know there is Device ini file, but this file itself cannot detect the power of CPU or GPU...

May be if the engine would have some implemented CPU GPU Benchmark which will state this device is slow, medium, or good (i know these terms can be quite relative, but some distinction should be needed..) - or return some numbers like Antutu or so, and then i will know, ok GPU 5000 points thats this quality etc.

Or how do you manage this problem?

Thanks for reply.

L.

Hello L -

A system like what you are describing is currently implemented, though the system is not reactive in nature but assumes a proactive testing of devices. First is the Device Profiles Settings which are kept in the DefaultDeviceProfiles.ini file.

You can find information about setting it up here:

https://docs.unrealengine.com/latest/INT/Platforms/DeviceProfiles/index.html

You can also make sure to address Material Issues with the Feature Level Switch, information on that can be found here:

https://docs.unrealengine.com/latest/INT/Engine/Rendering/Materials/ExpressionReference/Utility/index.html#featurelevelswitch

Again both of these used in tandem can be used to setup a project which will adjust its rendering and performance to a user's mobile device, but it does require a proactive testing on a device with similar CPU and GPU.

Thank You

Eric Ketchum
