Question

I want to call the Windows api to draw the text on the top of the screen, even in the full-screen mode of the game, it can be displayed. How do I do this?
I hope to be able to draw text that displays information such as the temperature of the graphics card and the usage of the video memory in the full-screen mode of the game
I tried it myself, but the text I drew cannot be displayed in the game in full screen mode. It can only be displayed in window mode.
I have been searching in Windows api for a long time, but I don’t know which one can be used.
I hope the expert can tell me which Windows API can realize the above-mentioned functions.
Thank you again, please help me

Please refer to the Question which has the same requirement. @RLWA32 had given a answer, running with UIAccess=true and with a window that is WS_EX_TOPMOST.

How is the xbox window displayed by pressing the win key + G key realized? What if it can be displayed in the front of the game in full-screen mode?
I really want to know, press win key + G key. How is the displayed window layer realized? Are there any API commands? Press the win key + G key. The window layer displayed can actually be the top and top of the screen
