Graphics quality in computer games is determined by several factors: higher screen resolutions, for example, guarantee contours without stairs. But the actual resolution of the textures is just as important as the final impression of the image. However, better textures also take up significantly more space in your graphics card’s limited memory. That’s why developers have long relied on block compression. Textures shrink like a ZIP file, saving up to 75 percent storage space. However, the procedure is associated with a significant decrease in tissue quality.
Sharper textures with the same memory requirements
Nvidia wants to use a technology called “
Little VRAM is provided
Compared to static block compression, the computation takes a bit longer due to the extra effort, but it only takes minimal more storage space. The result will be much more detail. Nvidia gives an example: Geforce RTX 4090 will need 1.15ms and 3.6MB to generate a single image based on NTC, while classic block compression takes 0.49ms and 3.33MB to do so.
More detailed textures thanks to NTC
The result was great. The images released by Nvidia can’t quite keep up with an uncompressed image, but they look sharper and more detailed than individual images created using the classic block compression process. With its new technology, Nvidia wants to enable more real-time gaming without greatly increasing the demand for graphics memory. At this year’s SIGGRAPH, Nvidia wants to reveal more details about the new technology.
