hi, i am running predator x34 and with the gsync/vsync combo turned on
my games are smooth but in fast paced shooter games like quake or team fortress, it feels kinda unresponsive,
if i turn off gsync and fps_0 in my console it feels much better although it is showing my fps up over 300...
will having such high fps damage my panel?
although its still smooth i do not notice any tearing without the gsync
and i just cant get used to the weird vsync style lag gsync gives you.
what are other peoples thoughts on this ?
 
When you reach 100fps on that monitor (presuming it's set to 100hz) g-sync reverts to v-sync. You need to limit fps under 100 so that g-sync is always active and thus the lag is similar to v-sync off. Try limiting to 5fps under 100 and it should feel much better.
 
No Vega
what i meant was the gsync makes it feel un-responsive.
ive run at 99fps and it just feels rubish
if you play fast fps games with no gsync it feels totally more responsvie
i cant explain why but i really cant get into this g-sync feature
i feel a smoother gameplay on my old acer 120hz screen with it set at 300fps?
dont know if it is just me but i cant see what all the hype was for this gsync.
:)
 
The correct setup for gsync is:

Gsync on, vsync on in NV control panel
Vsync OFF in game

You say you are running vsync on, but it should be off in game, worth checkng
 
When G-Sync is enabled what the V-Sync setting does in the nVidia control panel changes and instead controls G-Sync behaviour.

Rendering at 300+fps won't damage the monitor as the monitor is still running internally at the same rate.

Try capping at 94-99fps you may find that helps - 99fps with the rounding precision might still be effectively 100fps - but you might find that the update rate is just too low for your sensitivity to input latency and have to run G-Sync with V-Sync off.

Ultimately the Predator x34 is an IPS panel and despite what some people say the higher pixel response and typically higher latency than a TN can be less than ideal for fast paced games at what is ostensibly the same framerate that feels fine on a TN - the latency on this one is almost 3x the TN Swift at approx 9-10ms and I suspect some pixel transitions are pushing it close to double that effectively at times in terms of perception which is bordering on noticeable for high end gaming

No - when G-Sync is enabled the options in the V-Sync drop down menu change.

They don't. G-SYNC is controlled under the heading 'monitor technology'. VSync is controlled independently of this and can be set as before. The consequences of these options is explored in my review of G-SYNC models such as the Z35 and S2716DG.

It has changed - once you enable G-Sync under the monitor technology section the V-Sync option changes and affects G-Sync behaviour.

On the left V-Sync options with G-Sync enabled and disabled, on the right the framerates ingame with G-Sync on in both cases and V-Sync toggled in the nVidia control panel (144Hz refresh rate).

With G-Sync on, V-Sync on the max framerate will always be limited to the monitor max refresh rate and G-Sync will always apply down to 30fps with frame duplication used below that to bring the refresh rate upto a higher level and maintain the smoothest experience and shortest delay before the newest update is shown when the framerate recovers.

With G-Sync on, V-Sync off the system will render as fast as possible with no cap - upto the monitor's refresh rate G-Sync behaviour is applied - when you are capable of rendering faster G-Sync is automatically disengaged and traditional non V-Sync behaviour is used where you will get tearing but the fastest frame presentation - this gives the best compromise for games where you want ultra low latency response as when you aren't performance challenged the system is ticking over as quickly as possible and when performance does drop out G-Sync helps to preserve as good a possible experience as it can.

EDIT: As it could be confusing - the left hand does not show what settings are used ingame on the right hand - just the different options available with G-Sync enabled or disabled.

Your explanations are correct and exactly what I cover in my reviews. I misunderstood what you were saying initially. :)
 
Ah cool - was a bit surprised at your reply as I generally read your articles and thought I'd seen you cover it.
