I was wondering if there’s a tool out there that you guys recommend for measuring the GPU performance/usage (something like the ‘activity monitor’ in Mac or the ‘Windows Task Manager’ but for GPU). I tried using NVIDIA’s PerfHUD http://developer.nvidia.com/nvidia-perfhud but couldn’t get it to work with VVVV. Has anybody used it before? I’m using a Quadro 4000 card by the way.
