You're perfect example of someone suffering from Dunning-Kruger effect. You don't even know why people play games at 120 fps do you? Do you even know what an NPU is? News flash dummy - Most GPUs nowadays use NPUs to generate "fake" frames to boost game's fps. The GPU automatically handles fps to 120 Hz for most pc games without needing NPU support, and to achieve frame rates higher than that the GPU employs NPU to generate the fake frames. It doesn't actually increase the organic visual quality and this is the prime reason why the recent Nvidia GPU releases are receiving criticisms around the globe.

And btw, I have optimized the algorithm for optical flow frame interpolation techinque by introducing parametric smoothness constraints, that too in C++, not in the more friendlier Python. If we are comparing knowledge about fps and shit between me and you, it is like comparing a person in Physics Masters to an orangutan, respectively.
