Thanks for the info.
Would the method you said be almost as good as g-sync?
Because i'm choosing between 2 monitors and the one with g sync is 90 dollars more and doesn't have as good color representation as the non g-sync one.

Unfortunately, no. It is still going to have more input lag compared to gsync. With gsync, input lag is the same as vsync off. And if the game fall below 120FPS, it is going to stutter, which doesn't happen with gsync.

But it's better than default vsync though! I've been using this method for a long time before getting a gsync monitor.

So just to double check to make sure i'm not mistaken on this,
v-sync will work at any refresh rate as long as the refresh rate is constant?
Example, if I can't really maintain a 120fps signal but I can with 100fps then I can set the refresh rate to 100hz in windows display settings and that would work just the same as 120hz?

Vsync will always work, regardless of frame rate.

Vsync will be fine at 120Hz even if the game runs at 100FPS. The reason to switch to 100Hz is not to make vsync work, it's to avoid stutter.

I'm a bit confused here with pre-rendered frames affecting v-sync,
"For VSYNC ON, capping should be as tight as possible"
Don't I have to account for that 1 pre-rendered frame?
Won't I get 61fps per/sec with a 60fps cap it RTTS and cause tearing?

You cannot have tearing when you enable vsync. It doesn't matter what the frame rate is, or whether you cap your FPS or not.

The max pre-rendered frames ("MPRF") setting has no effect when the frame cap is reached, because the frame limiter prevents the game from rendering more frames and thus the frame buffers stay empty. This is the reason why capping your FPS reduces input lag.

If the frame cap is not reached, then the pre-render buffers get filled, increasing input lag. In other words, when the frame cap is reached, it's as if MPRF was 0.

That makes sense thanks, I had "Shao" on steam tell me otherwise.

This is innacurate:

"you will need to cap your frames at 59, why is that you may ask? While you cap your frames, the GPU still renders ahead of it's time, therefor the frames that are supposed to render ahead, such as the 61th of them will be introducing slight mouse lag"

The real reason why capping to 60 doesn't help much is because most monitors are not 60Hz, but rather 59.94Hz. and that means the frame limiter does not activate. To make sure the limiter activates, you need to cap slightly below your real refresh rate.

That's why the links I posted tell you to find out your real refresh rate and cap slightly below it, like -0.007FPS. If you cap to 60, that's either above the refresh rate or exactly at the refresh rate, and thus you get lag because the frame limiter doesn't get activates 100% of the time. If you cap to 59, you get micro-stutters.

I know this is a little of topic but here it goes,
I'm looking at getting a new gaming mouse and I am looking at getting the SteelSeries 600 and other people have said it can't do 1000hz without hiccups.
My question is, how do I know what is the true fresh rate of a gaming mouse?
I can't find any recommended gaming mice on BlurBusters and almost no other website take into account the real refresh rate of a gaming mice.

For mice, I always point people to Logitech.
