What is Android DXT?
DXT / Tegra: Used in the NVIDIA chipset integrated devices (Ex: Motorola Xoom, Nexus 7) ETC: Supported by low-level devices with Mali GPUs or some Chinese analogs (Ex: Samsung S3) ATITC / ATC: Used in devices with Adreno GPU from Qualcomm (Ex: Nexus One, Samsung Galaxy S5, LG G4)
What is texture compression in Android?
A texture compression format (or TCF) is a file format that is optimized for GPUs. The GPU loads and renders a texture quicker, and with less memory, than if it were using an array of RGBA values in memory.
What is ASTC and etc?
ETC2 achieves comparable quality with the same compression ratio, but is two-three orders of magnitude slower to compress. ASTC 6×6 has lower bit rate for the same quality, and similar compression speed as ETC2.
What is textured game compression?
Texture compression is a specialized form of image compression designed for storing texture maps in 3D computer graphics rendering systems. Unlike conventional image compression algorithms, texture compression algorithms are optimized for random access.
How does ASTC compression work?
Adaptable Scalable Texture Compression (ASTC) is a form of Texture Compression that uses variable block sizes, rather than a single fixed size. ASTC is designed to effectively obsolete all (or at least most) prior compressed formats by providing all of the features of the others plus more, all in one format.
What is ASTC cache?
The Adaptive Scalable Texture Compression (ASTC) technology is used by games to provide a realistic, high-resolution, 3D visual experience while reducing image data size, memory footprint, and loading time, to enhance the game performance.
How do I disable ASTC?
Here, locate the section “ASTC textures (Beta)” and click on the dropdown menu available under it. You will see three options in the menu, as shown below. Disabled: Selecting this option disables the ASTC feature on BlueStacks 5.
Does ASTC texture improve performance?
The rationale for the development of the Adaptive Scalable Texture Compression (ASTC) is to reduce data size, memory footprint, and loading time, yet deliver high visual quality for a given texture and increase the game performance.
Does texture compression improve performance?
The Adaptive Scalable Texture Compression (ASTC) format offers advantages, such as improved rendering performance, faster load times, a smaller in-memory footprint, better battery life, and improved visual quality.
Does texture compression affect performance?
Texture size should not have any effect on the performance. Texture compression can have a positive impact – the less space a block occupies in memory, the more blocks can be cached at the same time.
What is ASTC texture?
Does ASTC improve performance?
What is texture2 OpenGL?
A texture is an OpenGL Object that contains one or more images that all have the same image format. A texture can be used in two ways: it can be the source of a texture access from a Shader, or it can be used as a render target.
What is Cuda texture?
In the context of CUDA, textures are the mechanism by which data is retrieved through those computational units inside kernels running on the shader hardware. But the figure attached here taken from CUDA Best Practices Guide on page number 29, says that texture are memory and have some space as cache.
Why do DXT compressed textures always have the same size?
You have probably noticed that the DXT compressed textures always have the same size. This is because they have a fixed compression ratio. Because the resulting size is fixed, it also means that the quality loss of the compression depends on the original texture you used.
What is the DXT3 format for textures?
The colour information in DXT3 is saved similar to the DXT1 format without an alpha channel. So a palette of 4 colours is used to represent 16 pixels of the texture. But the alpha information is stored with 4 bit in the DXT3 format.
How do I add texture compression to an APK?
These asset packs are installed at the same time as the main application APK. Inside your asset packs, add directories for each texture compression format that you want to support. Add supported suffixes to the texture directory names that correspond to the texture compression format used for the contained files.
How many bits does it take to compress a 4×4 texture?
For DXT compressions the texture is split into segments of 4×4 pixels which are then compressed. These 16 pixels take 512 bits to store without the compression. When compressing a 4 colour palette is determined for these 16 pixels.
