Enabling and disabling vSync after renderer creation

I have an SDL_Renderer which I set to use or not use vSync (depending on the user). In my options menu I have an option for enabling/disabling vSync. Can I edit my renderer to update the vSync preferences so that I don't have to destroy and recreate it? Doing so would invalidate a lot of renderer pointers in my game, so I would like to find an alternative solution.

By the looks of it, no, it doesn't seem like this is possible.

I'm really disappointed by this. It's not possible to edit vsync after renderer creation and it's not possible to destroy and re-create the renderer since this would destroy every texture created...

Have you tried the SDL_HINT_RENDER_VSYNC hint ? By the looks of it, it overwrites the CreateRender option, and thus should work fine after the function is used.

Yes I tried that, not working. Plus the wiki clearly states that it overwrites the CreateRender option only inside the function itself.

I just needed to do this myself, and I was very surprised and just like Xriuk disappointed this was not possible.

Is there anyway to suggest it as a change for a future SDL versions ?
