Is it possible to receive a callback after rendering a frame?

Question

Iron

Hello, is there any way to get a callback when a frame is rendered by a video card (for example, in a game), and perform some calculations (with each frame). Or tell me which way to go.

Answer 1

First, ask a detailed question, it is not clear from your words what you mean, in the sense of what language is used, what kind of application, who renders, and so on.
