I'm currently developing a game and have implemented screen blurring when the player pauses the game using a shader. However, I've recently discovered that this significantly impacts game performance. How can I blur the background screen without using a shader when the player presses pause?
How do I implement screen blurring?

Well assuming the pause screen is static, you could blur it once, save the output, and just show that as a static picture.
I don't know how, though.
