That's too bad~ Really hope JPCT would support pre-compressed texture some day in the future ; )

Just another humble suggestion, how about if we have Texture class to have input from android.R.drawable as id. We can add one setting to determine we should grab the texels on demand. In that case, we can skip the virtualization part and save storage and processing power, bcause I notice storing texels can take some times too.

For illustration example:
Config.shouldVirtualizeTexture = true;
Texture t = new Texture(R.drawable.texture1);
//At this point, no texels are grabbed yet, but drawable id is saved.

//1. Later in uploading textures, grab bitmap from android.R.drawable and texels from the bitmap after that in Texture class.
//2. Upload the texels to GPU.
//3. Then dispose the texels and move to next textures.

What do you think? Is it going to be faster in this case? : )

Yup, that works! No more stuttering anymore. BTW, it's actually quite difficult to implement the function as I have many objects with different shaders. Can we have a generic function like compileAllObjects to compile the shaders and vertex attributes automatically? Is it difficult to implement?

Wao, it's 2x faster now! But only for subsequent use. It's alot slower for the 1st time. I guess I could stick with this for now. Are you planning to support pre-compressed texture anytime soon, or it's long way to go?

Hi Egon,

It seems like compressing texture takes a big amount of time to process. According to log, it takes around ~2306ms just to compress all textures. It would be great if we can provide the pre-compressed texture so it would be faster to process and we can save more battery. In my case, user will check how much battery my live wallpaper will consume in the phone settings. If users open and close the live wallpaper for multiple times, the battery consumption shoots really high because of the app initialization, which they will start complaining about the app.

For reference, here's the log during texture compression (Tested on Samsung Galaxy S4 with octa cores):

I guess I have to use normal map without compression then. Thanks alot egon.

Hi Egon,

I set my texture to mipmap and setTextureCompression(true), and it seems like the texture is pixelated and sometimes looks weird (some black area on part of the texture) for normal map, but it does not have the issue when compression is off. I'm using the shader code from http://www.jpct.net/wiki/index.php/Shaders. In addition, I tried out with the hello shader by setting all textures with etc1 compression, it looks quite different than what it is in without the compression. Is it normal that etc1 compression will lose texture quality? However, if the normal texture is compressed, it looks ok.

Okay, I thought it was always a separate compilation. How about the clear translation in texture matrix?
