Realizing that GPUPerfStudio is meant for windows, I decided to try it out under wine. It works great! Use winetricks to get the .NET runtime 4.0.
Well, I wouldn't be posting if I didn't have a question. I can connect the server to GPUTest (tess_x16) and run the client on the same machine under wine, and everything appears to work fine except the Frame Profiler window, which causes the program being monitored to segfault (GPUTest).
I don't expect the devs to prioritize this bug report, but here's what I'm seeing...
