(Not sure where to post this really, but I'm duplicating it here in the monitor thread as its own topic, as it's worth it!)....

I've been testing a lot of games since getting the Rog Swift, and whilst Gsync is great in many titles, I've had a few issues in some games where it felt like it just wasn't working right at all - Skyrim, BF4 to name a few.

Sometimes it's an SLI issue, sometimes it's an xbox 360 controller vs mouse and keyboard issue, sometimes it's just a game engine (see the Rog swift thread I posted in for more details).

After loads of testing and investigating, there is definitely nothing wrong with my system, or Gsync per se, as one of my biggest Gsysnc gaming disappointments - Skyrim with ENB - is now fixed, and here is my solution....

Open up your Skyrim ini file in your Documents\my Games\Skyrim folder and add the following line under the [General] section at the top:

iFPSClamp=60

This is an 'old' trick for Bethesda engine games, and somehow this completely sorts the awful micro judders I was seeing in Skyrim with Gsync running.
It's an odd fix in that it doesn't even limit your fps to 60 whilst using Gsync. My frames still go above 60 where it can. However, as I'm using ENB I've also set the built in frame limiter to 60 which saves the Ti's heating up more than they need to.
I'm also running the Swift at 120hz for this, but it also works at 144hz ok too. You can run it at 60hz but there is less motion blur at 120.

Skyrim is now the game I was hoping for with Gsync on the Swift. I used to be able to maintain 60fps with vsync most of the time at 1080p with ENB, but still used to dip into the 40s and 50fps mark at certain points which caused awful judders. Now Gsync is doing the job as advertised. Am well happy!

So, hope this may be of some use to anyone out there experiencing less than stellar smooth performance with Gsync and Skyrim ENB, like I was. :)

Can you try this too...

Revert everything to as it was pre-fix, load up the game and hit the refresh overclock button twice to 144hz and see if that helps.

I say this as fifa 14/15 does a similar thing, the engine throttles at 60fps forcing 60hz resulting in stutter, doing the above 100% cures it and caps frames at 144fps without any software tweaks.
 
i used NVI to cap the framerate to 75fps with Skyrim and with g-sync that means the monitor is at 75Hz and it feels just as smooth as 120fps/120hz
but without any of the weird physics bugs and flickering textures

gamebryo engine doesn't like 120/144Hz
 
Great info Wunkley:) I've been thinking of reinstalling Skyrim so it will come in handy! Thanks for posting:cool:

No worries :)

Already tried at 144hz before this fix. It was ever so slightly better than at 120hz for some bizarre reason, but still had awful micro judders. With this iFPSClamp=60 fix the difference is night and day, whether running the monitor at 60hz, 120 or 144.
 
what is enb, is it a texture pack, the reason i ask is that i have a single 780 ti, and i have vsync on and i never dip below 59.9 fps at a higher resolution that yours ( 2560 x 1600 ).

Was just a thought is all, as I say, it cured it for Fifa, as even though my system was set up for 144hz the game forced 60hz, hitting the OC button sorted that and stutter :)

Edit: have every intention of modding fallout 3 and giving that a proper play through again so this fix should work on that too :D

Google it my friend. Enb takes a fairly average looking dx9 game and takes it to another planet. Look up 'enb skyrim' and then 'nexus mods skyrim', put aside about a month of your life downloading/ reading/ experimenting, and then get back to me.
It's addictive, frustrating, but ultimately brilliant. But beware, skyrim enb with all the bells and whistles activated, is one of the most taxing GPU killers out there. 2x Ti's can just about do it justice.
Once you get a good enb set up and working, texture packs and loads more modded up, and all running well, I would argue that at times it's one of the best looking games out there, still.

I came across this thread in the hope of fixing the same Issue as the OP however I'm running Gsync on a 4K display at 60Hz.

Initially the iFPSClamp=60 worked on modded skyrim without an ENB. However when I installed the ENB (Realvision ENB to be precise) the game appeared to play in slow motion. Not stutter or tearing but just extreme slow motion.

This is because iFPSclamp actually isn't compatible with ENB as far as I am aware - or at least at 4K 60Hz displays it isn't. The problem can be fixed by lowering the value. iFPSClamp=0 will provide no FPS lock at all. This is value I have set mine at and had some success.
 
I used to use Riva Statistics and lock the FPS to a max of 59fps to cure problems like this.
Could probably do the same for 119mhz ?

Thanks for ths info i now own a 980 ti and the Acer XB280HK (4k gsync) - the same monitor as you i assume.

I'm just installing skyrim and all the mods now. so to be clear if i set iFPSclamp=0 gsync will work with enb ?

thank you.
