Martin said:This is unfortunately a limitation of those GPUs. Raven-based GPUs (APUs) are unable to report GPU usage, the only semi-reliable usage value is the GPU D3D Usage.
Martin said:Sorry for not being clear too. There are two kinds of usages reported by HWiNFO - an internal usage value called "GPU Utilization" and other various performance usage counters including Video Encode/Decode and Computing values.
The first internal value cannot be reported on Raven series, the latter ones depend on drivers. I have analyzed the debug file you provided and GPU drivers in this case don't provide any performance counters. So it looks like a bug in latest driver versions. Are you able to see GPU usage in Task Manager for the Vega?
Martin said:What various GPU usages do you see in Task Manager? HWiNFO should be able to provide the same values, but it wasn't able to find any of them there.
