I see. Perhaps then in your specific case, it could actually be Nvidia's framerate limiter that is changing its behavior in the latest drivers, and not G-SYNC's borderless/windowed mode?sfbb2 wrote:@jorimt, Yeah I am using Windows 10 1709, but I have the feature that includes fullscreen optimizations completely removed.
Most games some sort of tweaking with nvidia profile or rtss to work well, but g-sync borderless has worked generally well for me prior to 390.77. Driver version 390.65 works great, but everything after that has been pretty bad.
For example, HotS I use 141 fps cap with v2 limiter in 390.65 and it is very smooth. With 390.77+ it is terrible - gets a bit better using the default instead of v2 limiter but still not as good as 390.65.
FYI, when I tested Nvidia's FPS limiter with G-SYNC (https://www.blurbusters.com/gsync/gsync ... ttings/11/), they weren't very compatible, and there was considerably more lag at the same FPS limit when compared to RTSS.
Have you attempted the same configuration in those games but with RTSS instead, and if so, is it any better?
If you have, and G-SYNC borderless/windowed mode is still acting up, then yes, it is probably related to the driver. I don't personally use the mode enough to tell a difference from driver to driver, and if the game doesn't have it's own limiter (or the in-game limiter has poor frame pacing), I only use RTSS.
