Is it possible to slow down a program to give it more CPU time to execute?

Question

Windows

In particular, directx games. When resources are low, most games start dropping frames, making the video sequence "ragged", but maintaining the pace of execution. The opposite is required - a constant slowdown of the program to create the effect of a more "smooth" rendering, albeit at the cost of a real slowdown in the gameplay. Is it possible to implement this?

Answer 1

That is, in addition to the "slide show", you want to add brakes to the logic of the game itself?
It will not work smoothly if it takes a second to render the frame, you will wait this second until the frame is drawn.

Answer 2

Is it possible to slow down a program to give it more CPU time to execute?

You can slow down a program by giving it less CPU time to execute.
More time is faster, less time is slower.

to create a more "smooth" rendering effect,

What is it like? The program will work more slowly, therefore, it will send frames less often. As a result, you will see one frame, go for a smoke, and you will see the second, and so on.

Answer 3

Firstly, frames are a rather complicated thing. No frames are the same. One can be calculated for a long time, the other quickly, the third one can be drawn out of the two. Therefore, if the frames do not have time, and you want to linger, then you will have a jerky game, which either speeds up or slows down.
Well, in any case, this cannot be done from the side, it must be done from the side of the application itself. You can't fix someone else's game at the expense of the driver.
