When checking out G Sync monitors I was surprised to see that some do not refresh below 40hz which would not be suitable for GPL at 36fps so that is one thing to look for when buying a G Sync monitor.

I would be amazed if Gsync forced your monitor down to 36Hz refresh rate when you're running GPL at 36fps. My bet is that it's far more likely the monitor will refresh at 72Hz or 144Hz. Low refresh rates can cause flickering of the display, which is visible and irritating to me even at 50-60Hz. (Edit: At least that used to be the case when I was running a CRT display. With my flat screen, 60Hz seems fine, but I wouldn't want to go any lower than that.) I can imagine 36Hz would be unbearable. Does Gsync really behave like that? If so, I will never be using Gsync!

First impressions very good.

I ran two races against the AI from the back of a full grid, the first with 69x at Montjuic which before had stutters in places but now smooth.
The second was 55 at Spa67 which also had stutters especially at the tighter corners but tonight I did not notice a single stutter.

I am not sure what G Sync is actually refreshing the display at because there is nothing to tell you but it is smooth with no noticeable flicker.


With GPL running at it's native 36fps the AI work great without having to do anything and gone are the vsync stutters or tearing problems.


I need to do some online races to give a final verdict but so far I would say this is the best I have ever seen GPL ( and that includes trying the 60fps patch with my old 60hz monitor )

Even though we're not exactly sure how it's working, I'm glad it's working for you! :thumbup: :clap:

Thanks Saiph.

At first I had G Sync enabled globally but soon found video does not stream well so now I only have G Sync enabled for games that I play in the Nvidia control panel profiles. My desktop runs as a normal 144hz monitor and G Sync only starts up for games applications (games) I have selected.

It is so hot here at the moment I have not tested as much as I would like but I intend to disable G Sync for a side by side test with GPL and see how 144hz on it's own compares to having G Sync enabled.
