Does sync affect gpu load?

[Carz728]

I currently own a Vega 56 and almost every game on max settings causes the gpu to go to max load all less are on and the fan is very load. However recently I have been turning vsync on and my load has stayed the same and never goes to full. Just wondering why this is and will double buffering affect my gaming performance?

You see on default the GPU will draw as many frames as it possible can, when you turn v-sync on you're telling the GPU to limit how many frames it'll draw to the hz of your monitor.

 

So if before it was drawing say 100 frames on full 100% load you turn on v-sync with a 60hz monitor it'll fall back down to 60 frames drawn per second, and your usage is now of only 60%.

 

Techinically you're not losing any performance, you're just not drawing more frames per second than your monitor can display.

Ok thanks for the response.
