Depending on how the workload is structured, you would want an average load that takes into account bursts and idle periods. GPU-Z seems to not do that. Spiky 0/100 graphs are not very useful.

madVR is rather special in how it works load-wise, because it has practically no CPU limit, so when it can work it'll work 100%, but it has a hard frame rate limit, so it doesn't have endless work - ie. very spiky behavior. An ordinary 3D renderer would be CPU limited and/or capable of rendering an unlimited amount of frames, so it would either always cap the GPU, or be limited consistently by the CPU, but not simply by "time".
