A fast version of ericson texture compression. This has four workloads. The first two look multi-threaded and the last two single-threaded.
Topdown profile shows an overall higher retirement rate with some backend stalls. Branch misses look higher than average.
AMD metrics show floating point code, low levels of L2 access. Backend stalls are more CPU than memory.
