FPS drops using vsync

[Mysterious X]

My game can go up to 100 FPS but using vsync can sometimes make it to drop 58 or 59 which causes a stutter and does it not happen every time only every 15 or so seconds and other times the same game can run at a flawless 60 FPS, i can't find a consistent pattern to all this which might help me pin point the problem so any answers will be appreciated, also it does not happen with every game

My PC specs are, i9 12900k with RTX 3070 and 32GB RAM

You do realise that vsync will lower your framerate anyway right?

The point is vsync is a stability setting that locks the framerate of the card or chipset with your display. So in other words it LOWERS the framerate until it finds one that locks in time with your display.

Now, it's feasible if things are a bit out of kilter that you may get stutters as it may be trying on the fly to adjust.

The first thing I would suggest is having a good old pay around with different resolutions and other settings and monitoring your Task Manager at the same time.

It may be you're now pushing the CPU or GPU etc just a little overboard causing the stutter. In which case, you need to either lower another setting that is intensive in your graphics settings in game, or try a lower resolution until it clears.

i tried lowering all graphics settings to mid to high and texture settings to low with 1080p resolution and it does not seem to make a difference, if the stutters are going to happen that time then then it well, turning DLSS off would magically smooth it out while sometimes turning it on would also do the same and other times no difference and if i restarted the game that would also work, like i said it's inconsistent. The game in question is black ops 6 in case you're wondering which uses shader compilation. Shader stutters?

That's why I detailed what you need to do to finesse it.

Open Task Manager while you're trying out toggling options and reducing settings, because some settings obviously have more impact than others. But you can't tell unless you look at something like Task Manager or other monitoring software to see HOW MUCH effect it has.

Then you work out which ones you want to keep, which ones have not much effect, which ones do, and so on.

And you'll find out where the sweet spot is in regards to how many percent usage your system resources will tolerate.

what should i look for in task manager while changing the settings?

So ok you need to understand that vsync as a technology is designed at its core to prevent visual tearing. That is its goal. It doesn't care about anything else other than this.

VSync always 'limits' your frame rate into discrete increment.

Basically your game will run at eitehr 30fps or 60fps

If your FPS is over 60 then vsync will lock it to 60fps

But if your fps drops below 60, then vsync will drop your fps to 30 to prevent tearing. So what you're seeing is normal because once you go below 60fps vsync then caps you at 30fps to prevent screen tearing


Now in modern times, various GPU makers have implemented different technologies to limit the downsides of vsync. You should look into your GPU and see what they have. There are thiungs like adaptive vsync, dynamic vsync, etc that are GPU maker dependent and might require specialzed hardware on your monitor (such as being GSync or FreeSync monitors). Other technologies are monitor independent.

Again what technology you can use depends on your GPU, as well as your monitor.
