However, not all applications can read or load the newer BCn compression formats - This free sample code will allow you to implement optimized BCn in your app. saves disk space and transmission time over the internet but have no impact on optimizing textures for use in graphics hardware memory whatsoeverĪ2: BCn optimizes textures for real-time use in graphics memory and saves space on disk. Q: Why would I use BCn over lossless PNG?Ī1: PNG, JPG, etc. Effective texture memory management (compression), is still required to keep pace with this demand.Ī: Higher bit depths and or finer (slower) compression formats (e.g. Q: Why do we still need texture compression?Ī: Demand for more realism in games via textures has increased with every new graphics hardware improvement.

BC1a, BC2, and BC3’s Fastest modes now use the GPU for compression.Switched to using FreeImage instead of OpenImageIO in the standalone exporter for import and export of non-DDS images.The corresponding command-line options are -read-flip-y and -save-flip-y. Added the ability to read and save images flipped vertically.Added support for reading three nonstandard BC6/BC7 FourCC codes (BC6H, BC7L, and BC7\0).Added support in the plugin for reading alpha channels of DDS files as extra channels instead of transparency.Added support in the plugin for reading mipmaps of DDS files as layers.If you’ve hidden the read settings window, you can re-enable it from the About box. These settings are automatically saved in the registry. Added support for read settings in the plugin.The corresponding command-line flag is -dx10. This should improve compatibility with older DDS readers. Added an option to always use the DX10 header extension, which is disabled by default. Both the plugin and the standalone exporter now export using DX9-style DDS headers when they can (i.e.Support reading legacy DDS files where dwMipMapCount is 0.Fixed issues with compressor nondeterminism on cubemap textures.Fixed an issue where using two identical GPUs in a non-SLI configuration without a specified CUDA device would lead to image corruption.Fixed an issue where the Photoshop plugin would choose the wrong channel for alpha when the Photoshop file didn’t have a background layer and had a user-provided alpha channel.Added Boris Ustaev’s image drag-and-drop UI.Image effects now run on a background thread, making the user interface respond faster with larger images.

Added window resizing and high-DPI support.Added KTX and KTX2 file format readers as well as support for exporting KTX2 files.Added NGX Super-Resolution effect for Turing+ GPUs.
