Texture Reads
Description
The metric GPU Memory Texture Reads represents the number of bytes read by the GPU from texture memory when rendering this frame. Note that the Texture Sampler reads data from memory in 64-byte blocks, so this metric can be used to calculate the number of texture cache misses.
Examples
- If GPU Memory Texture Reads is 64000, it means the Texture Sampler missed the cache 1000 times and needed to read 64000 bytes of memory.
- If GPU Memory Texture Reads is 0, it means that no texture data was read from memory for selected ergs.
Improving Performance
Usually a higher value for this metric will lead to a higher percentage of Texture Sampler stalls. Therefore, utilize techniques that minimize the number of texture reads, such as shown in “improving performance” section of the Texture Sampler Stalled metric.
