Could be a problem with the GPU's power state then. Power states determine the speed of the GPU, and normally it should switch to and stay at P0 (maximum performance) automatically when running 3D applications. Ive been experiencing some strange behaviour with that though, especially with older games, or when using more than one monitor.
I guess you already got a GPU sensor logger (msi afterburner or something). Use it to check if the clock frequencies change when the FPS go down. This indicates the power state problem. Then you can use e.g. "nvidia inspector" to force P0 when running certain applications, which should fix the problem.
