As far as I understand vsync should always be on with gsync no matter the cap?

G-SYNC on + V-SYNC on vs. G-SYNC on + V-SYNC off is my most frequently asked question, and is answered in more detail in the second entry of my Closing FAQ:

I've been doing some tests. I've noticed with vsync enabled and gsync enabled with reflex + boost when I'm in a game during intense parts my fps drops, I notice incredible input delay. Such as swinging my weapon it feels very sluggish and slow. Is this because of vsync?

I tried disabling vsync ...

I was checking my gpu and cpu usage and it's completely normal but my fps would drop from 158 to around 100 and then it happens briefly.

If that results in the game looking like it's momentarily visually pausing, that's frametime spikes.

And in that case, It's not only dropping to, say, 100 ...

You can't 100% prevent frametime spikes, which are heavily game/engine-dependent, and are sometimes ultimately limited by I/O operation (how well/fast data can be swapped from the SSD/HDD to RAM/VRAM) .


Maybe I'm misunderstanding the problem I have. For example I did a raid in World of Warcraft ...

edit: i restarted my pc and did the test again without disabling anything, its the same result I posted above. So I guess everything is fine now?

It's up to you to decide whether everything is okay or not. If you see less blue and red, then you are going in the right direction.


Awesome. I ...

IMPORTANT: Close all applications & close all other browser tabs;
Close all RGB system tray software & other inefficient background software;

Use primary monitor only, or use single monitor mode instead of ...

Also I used some blurbuster tools such as the vsync one. I see alot of red and cyan, why is that? https://www.vsynctester.com/

i reach 158 fps but sometimes my frames would drop below 140 randomly which is causing game stutter, any idea whats up with that?

I should always turn on ultra low latency to ultra in nvcp by selecting the game individually if the game doesn't not have reflex + boost inside the game, right? Just want to clarify.


Yes, If G-Sync is enabled, ultra low latency will automatically cap a few frames under Max Hz. I ...
