Is there a faster way to display video than NamedWindow and WaitKey? (Linux)(Python)

I'm working on a real-time video processing application, and I need as little latency as possible. I'm suspicious that the standard namedWindow and waitKey solution is adding delay, because there is about 100ms of lag when it should be closer to 30. Also it is a bit superfluous because my application will be run on a system with no keyboard. It seems to take a lot of CPU power to display too, which I would like to cut down if possible.

So is there a faster/less CPU-intensive way to display my video feed? Something like DirectX, but on Linux?

Thanks.
