I have an HP Envy 15t-3200 with switchable graphics. Performancetest does not detect my graphics card and uses the intel graphics 4000 instead. When I use catalyst control center to switch performancetest64.exe to high performance amd graphics, performancetest crashes immediately upon startup. Any ideas?
Not working with AMD 7770M Graphics

First thing to check is that you have the latest video card device drivers installed.
After that can you send us a debug log. See this page for details of how to collect a log file.
