Lock to 60 FPS or VSync?

Since there are so many helpful people here, I'll continue to ask my questions. Sorry in advance, I'm 90% sure this has been discussed on the forum before, but honestly, I couldn't find anything.

I did it through user_a2.cfg. The developer of the universe mod added the ability to enable vertical sync from the game settings; it's unknown why the game developers didn't add this option.

I also tried it through user_a2.cfg, but I didn't like the result. It seemed like the game would apply the settings after a while (after starting), and it would also stutter in some places. Plus, VSync itself puts a load on the game (although a very small one). But when I used the Nvidia app to simply lock the frame rate at 60fps, everything became perfect. I didn't see any issues with the graphics or loading, and it's only 60fps. Plus, the computer became even quieter than with VSync.
