If you want to call [glfwPollEvents()](https://www.glfw.org/docs/3.3/group__window.html#ga37bd57223967b4211d60ca1a0bf3c832) more frequently than you update your rendering then the usual approach is to move the rendering to another thread, and use [glfwMakeContextCurrent](https://www.glfw.org/docs/3.3/group__context.html#ga1c04dc242268f827290fe40aa1c91157) on that thread (if using OpenGL).

You can find a bit more information in posts here if you search for multithreading, including [this one](https://discourse.glfw.org/t/multithreading-glfw/573) where @elmindreda explains the OS requirements for why glfwPollEvents must be called from the main thread.
