G-Sync got worse??

RichardH754 · 1 Dec 2016 at 13:22

Has G-Sync gone bad just lately or is it me?

It seems that Dishonored 2, it won't work

and some others don't seem as smooth as they use to be

beany_bot · 1 Dec 2016 at 13:25

What GPU are you using? Maxwell by any chance?

Nasher · 1 Dec 2016 at 13:33

I had a few games that just didn't seem to like G-sync when I was using it :/

RichardH754 · 1 Dec 2016 at 13:43

1080 SLI, it just don't seem as smooth on some games as it use to?

Rroff · 1 Dec 2016 at 13:46

Dishonored 2 uses the idtech "6" engine which doesn't use exclusive fullscreen mode so getting G-Sync to work is a bit hit and miss - if you don't have fullscreen and window mode G-Sync enabled it definitely won't work at all.

If you are having smoothness issues make sure you aren't using the Fast V-Sync settings (FastSync) with G-Sync.

nVidia seem to be dropping the ball a bit on G-Sync the last 1-2 months though

I've noticed a few times where it just drops out for a few moments now and again in some games or sort of works but sticks to V-Sync multipliers quite a bit.

Maybe they are going to ditch it in favor of adaptivesync. They are going to have to stop using display port 1.2 at some point

Simon Belmont · 1 Dec 2016 at 13:57

G-Syncs awesome. It's that game that is worse. Newer games are just developed bad.

Technically until some changes happen with Adaptive Sync G-Sync is actually the superior technology i.e. it has a wider variety of compatibility with applications and games that don't use exclusive fullscreen mode and can use additional buffers thanks to the FPGA to somewhat mask the effects of low framerate. So it wouldn't really make sense to drop it for AS - though I hope nVidia get over themselves at some point and also support it.

wait. so Dishonored 2 doesn't run in exclusive fullscreen?? that's even more annoying for us Freesync users as it means Freesync is completely off.

I'm not 100% on whether its bugged in Dishonoured 2 (as some suggest) or like idtech 6 doesn't have a proper exclusive fullscreen mode but it appears that the fullscreen option doesn't work as an exclusive fullscreen mode.

I can only comment on Doom and that is idTech and freesync 100% works in that title I tested on and off

From using (and owning) both, there is very little between them really. The end result is the same. Except for the windowed mode issue, but that is a driver thing.

I've had just as many freesync problems with certain games as I did with gsync.

That's down to their & AMDs implementations to solve, not the adaptive sync standard (which NVIDIA do support, just not on desktop GPUs at the moment)
Edit: Or MS. Same idea tho

I notice some difference when framerates are dipping to around 40fps though that isn't an ideal situation on either side.

The issue with windowed mode is a Windows/Microsoft one really and not down to a AMD, VESA or nVidia issue really - even nVidia uses some fairly nasty "hacks" with the benefit of the FPGA to make it sort of work.

I might be wrong but I think Doom uses idtech6 while the void engine in Dishonored 2 is based off what is really "idtech5.5" with some stuff added in from idtech6. I'm still not 100% sure what the status of exclusive fullscreen mode is in the game.

Gregster · 1 Dec 2016 at 17:00

When I was running SLI, microstutter was noticeable and irritating but a single GPU was and is flawless for me. Make sure VSync is off in game options. I also believe that D2 is quite poorly optimised.

I still have wolfenstein installed if that works with freesync then I guess they all will.
Will test later

ArmitageShanks · 1 Dec 2016 at 17:10

I thought GSync/Freesync is between the primary card and the monitor - the game doesn't get involved or even know it's there. If I had to blame something, I'd blame poor optimisation in the game, or microstutter from SLI.

if gsync isn't working at all, it's usually because the game or nVidia driver isn't disabling vsync properly, or it's running in a windowed mode locked to the desktop framerate.

tommybhoy · 1 Dec 2016 at 17:17

Agree with greg mgpu is more likely the problem.

I found the same too having used both.

It's game dependent on how good/poor low fps is produced on screen when your hitting those low fps at the bottom of the range, some are manageable, others terrible, low fps is low fps and not even AS can help-imagine most will agree it's not a magic bullet for low fps.

Dishonoured 2 working fine 4k gsync here, maxwell titan x

In my experience in an otherwise comparable situation G-Sync masks the nastiness of low framerates better than FreeSync - at the end of the day its not an ideal situation whichever setup you are running though.
