I've installed WPA version 6.2.9200.16384 and WPR version 6.2 (Build 9200) on a Windows 8 machine and a Windows Server 2012 R2 machine. When I collect a CPU trace with WPR I don't get a CPU Usage (Sampled) graph in WPA graph explorer, only CPU
Usage (Precise). The same thing happens when I use xperf -on latency -stackwalk profile. If I try to use xperf to view the etl file I get no drop-down for a table or summary table.
