Question by lc0034 · Aug 08, 2018 at 11:00 AM · texture compression

About android graphics api and texture compression

Graphics api settings and texture compression are being tested.

First test

After enabling 'Auto Graphics API (PlayerSetting - Other Setting)' and building it on Android, I confirmed it in 'Memory profiler'.

The texture size is 1024 * 1024 with alpha channel.

In the texture importer, the compression format is 'RGBA Compressed ETC2 8 bits'.

The memory usage of this texture is 1MB (in memory profiler).

And .. the second test

I disabled 'Auto Graphics API (PlayerSetting - Other Setting)' and added only OpenGLES2 to the Graphics APIs.

When using the above texture, the memory usage of this texture is also 1MB.

I know that OpenGLES2 does not support ETC2 compression format. Why does it have the same result (memory usage 1MB)?

P.S - The API version of the Android device is 6.0.
