GSync and Double/Triple buffering in WoW

Talk about NVIDIA G-SYNC, a variable refresh rate (VRR) technology. G-SYNC eliminates stutters, tearing, and reduces input lag. List of G-SYNC Monitors.

GSync and Double/Triple buffering in WoW

Post by soupman815 » 21 Jan 2020, 09:38

Hi Guys,

I am thinking about getting a Gsync monitor soon, read up on Blurbuster's Gsync101 guide. In the guide it suggested to turn off both double and triple buffering.

What I soon realised is that you can't actually turn both double/triple buffering off in wow, you have to select one.

I guess my question is: which one should I select? Double or triple buffering? Or is there another way to disable it completely?

Any advice here would be greatly appreciated!

Cheers,

Always double buffer with G-SYNC. For games that force V-SYNC like this, you can leave the V-SYNC option for the game profile on "Use 3D application setting" in the NVCP, which will adhere to the in-game setting instead. 99% of the time, there isn't a difference between in-game and NVCP V-SYNC when used with G-SYNC.

Also, I don't play WoW, but are you sure V-SYNC can't be disabled for that game? Because the below support article says it can be (might be outdated though):

Hi Jorimt,

Thanks for the response.

You can disable Vsync, yes, that's a separate option. But there's another option called Triple buffering (enable/disable). When disabled, it will default to double buffer. Hope that makes sense.

So you can disable v-sync in game, but enable triple buffering at the same time. They do not fall under the same category of options.

If that's how it's setup in that game, those should only apply when V-SYNC is enabled. So the double buffer in-game option + in-game OR NVCP V-SYNC should work fine when using G-SYNC.

Actually, another quick quesiton.

Should I OC to 160hz or higher even if I can't reach that FPS consistently?

Also, if running Gsync + Vsync on (NVCP) + ingame fps limiter 141 (for 144hz), and the fps drops to 100 or even 80 during intensive moments, will that lower the refresh rate? and if so, will that feel laggy / stuttering compared to not having gsync on?

This depends on the monitor model and how well it overclocks, as well as how well it implements overdrive with the overclock; some models exhibit increased overdrive artifacts when overclocked.

When compared to standalone V-SYNC in the same instance, which will introduce lag and stutter, quite the opposite (as for lowering the refresh rate, I answered that in a reply to your pm). That said, less frames per second is less frames per second, G-SYNC or no G-SYNC, so 80 FPS simply isn't going to feel as fluid as 141 FPS, especially if it fluctuates between the two rapidly, as it doesn't give you time to acclimate, so the contrast between the two becomes more obvious than if you had a constant locked 80 FPS or a constant locked 141 FPS.

Many users chose to deal with this lack of framerate consistency by setting an FPS limit at a framerate their system can sustain 99% of the time or lowering settings to achieve a higher average framerate.
