Very impressive! Have you looked into pyqtgraph? It's based on the widely used PyQt/PySide packages. Using the included video speed test, I am able to process a 512 x 512 picture at nearly 1000 fps (though my monitor is capped at 144 Hz) with an RTX 2080 Ti. I encourage you to open up the examples and see what capabilities it has for your system.
You can run it yourself here, just set the interval to the value you want. There are still short occasional "halts" though...
