Re: Overwatch -- Lightboost 120Hz + Fast Sync

No, fast sync will let the game run faster than the refresh rate, and will drop the extra frames. You can tell it's working if there's no more tearing.drmcninja wrote:I'm trying to enable Fast Sync, but I'm not sure it's working.

https://www.youtube.com/watch?v=sITJ3V_fyv4No, I actually did do a Fast Sync comparison in my original input latency tests, albeit only at 144 Hz:RealNC wrote:We did G-Sync input lag tests for CS:GO. Nothing for fastsync at this point though, sorry.
It didn't add much latency at 144 Hz uncapped (fps_max 300 in CS:GO); this will of course vary depending on the current max refresh rate/sustained fps ratio. The last official word from Nvidia was that Fast Sync has around 8-15ms more latency than v-sync off on average:

For the upcoming part #3 of my ongoing G-SYNC 101 article however, I will be comparing G-SYNC input latency against v-sync off, v-sync on, and Fast Sync across all available refresh rates, with multiple scenarios covering uncapped and varying levels of capped framerates.
Keep an eye out at the top of the below thread, along with the Blur Busters home page and social media pages for updates:

I enabled it for Overwatch.exe and Overwatch Launcher both in Nvidia Control Panel, but in-game my FPS is still showing 300. When I lowered it to 140fps with the in-game limiter, I could tell my FPS just dropped significantly, everything began to stutter and mouse movement felt different. My refresh rate is 120 so if Fast Sync was really enabled, it should've been outputting 120fps the entire time so I shouldn't have felt a difference no matter what the fps limiter was set to, no?
