Applications that prevent GPU PerfStudio from working

Fraps

Do not run Fraps with applications that you want to debug with GPU PerfStudio. Fraps uses a similar technique as GPU PerfStudio to intercept the DXGI Present function call and this prevents the tool from working when Fraps is running.

Raptr

Do not run Raptr with applications that you want to debug with GPU PerfStudio. Raptr uses a similar technique as GPU PerfStudio to intercept the DXGI Present function call and this prevents the tool from working when Raptr is running. Raptr is installed by the AMD Catalyst driver installer by default. After updating AMD graphics drivers you will need to uninstall Raptr.

Applications running on port 80 (e.g. Skype)

GPU PerfStudio uses port 80 to communicate between the GPU PerfServer and the GPU PerfClient and this will conflict with other applications running on the same port. Shutdown any port 80 apps or you can configure GPU PerfStudio to use another port by changing the PerfServer and PerfClient settings.
