I'm having a performance issue in a Win32 program and I'm trying to figure out whether the GPU or the CPU is the bottleneck on a Win32 program in Windows 8 (it does the same thing on the same hardware under Windows 7, I just happen to be using Windows 8).
I created a trace using WPR where I checked the GPU Activity option, however WPA doesn't show any graphs related to GPU activity.
Is there something I have to do to view GPU activity analysis in WPA?
GPUView crashes when I try to open the trace, however it is able to open a smaller one of just me messing around on the desktop (WPA shows no graphs related to GPU activity on this one as well). The proper trace is large (~1.3GB), so I have a feeling this
might be a cause.
If I can't view GPU activity in WPA, is there something I can do to make this trace open in GPUView?
