Question about v-sync

FastSync and V-Sync are completely different things.

 

V-Sync will always try to match your FPS to the Refresh Rate.

Fast Sync on the other hand will always try having your FPS Above the Refresh Rate.

 

Both try to eliminate screan tearing through different methods, FastSync decreases 'input lag/delay' that may sometimes be caused by V-Sync.

Hi all,

 

I have recently purchased a 1440p/144Hz screen (Samsung LC27JG50) and I am fiddling with my 1060 6gb a bit to get the most out of it. I manage to get decent framerates and in some games like CS:GO I can use the 144Hz. I was tinkering with the v-sync a bit, and decided to put the v-sync setting in the control panel to 'fast'. MSI Afterburner still shows a framerate of 200+ though. My theory is that the since the GPU still creates the frames but they are just not pushed to the monitor, MSI Afterburner shows framerates over 144Hz. Is this correct or is the setting not working/am I not understanding this properly?

 

Thanks :)

are you sure that v-sync is on cause it should never go above the monitor refresh rate. maybe the fast setting lets it go above it only a little bit but ive never seen that before

Ah okay, so the fast setting in vertical sync is called FastSync. Yes this clears things up and confirms my theory. Basically the gpu is adding 200+ frames per second to the buffer and then only 144 are actually pushed to the monitor. Thanks!

Yeah so apparently this isn't the same as regular v-sync, it's just a bit unclear since it is located under the name vertical sync in the control panel.
