Hey guys I just have a question for you all. Hopefully someone out there can help me out. 
 
Yesterday I bought a Asus RoG Swift monitor; I was super excited to get it home and set it up. During set up I made sure to set up the g-sync function and have correct optimization for the games I was playing. However when I loaded up a game I noticed a severe drop in frame rate. My system is pretty high end so I am use to frames 80+ in pretty much everything at ultra on 1080. I exited the game and use the geforce experience to optimize the game and its settings were the same as what i preset. But the frame rate did not increase. It would take a solid 4 minutes to just load to the main menu. 
 
I was testing it on the Tomb Raider Re definitive edition with ultra settings at the monitors native 2560x1440 res and at 144hz. When i was experiencing these issues. I pushed the monitor down to 60hz and it acted completely normal. But i dont think the extra hz would truly cap out my system like that.

Maybe i am missing something in a setting, or there is a issue because i am on windows 10; so possible driver issues. Anything will help me out just dont want waste the 700 i dropped on this monitor.  

No i am talking like from 80+ to below 10 frames. Its a staggering difference makes the game unplayable.

Yep.
I was looking through error files and my gpu driver had failed but it reloaded correctly and the issue continued to happen. 

I am not sli'ing at the moment i heard off issues with it, but i didnt have any issues with a single card till i upgraded the monitor. 

It only has display port cables, so i have a display port to display port 1.2 cable connected

No I'm not using the cable that it comes with. I bought a cable from Amazon from cables matters that was suppose to be better. Would you use the cable it came with?

It's weird that gfe would cause that much issues with the card. I'll have to try to get rid of it tonight, although I did like shadow play.

I am signed up for the beta drivers so I'm at the absolute newest one, I checked for updates thru gfe last night when I noticed the issues

Okay I'll have to check it when I'm back from class
You have any other suggestions that could be wrong if that doesn't fix it? Or if I am at 355.80

I am running windows 10 x64, NVidia drivers 355.80, 680 SLI and RoG swift with no issues at all. The difference between 1080 and 1440 is huge, you need to turn some settings down if your only using one card.

Gfe=bad can't explain that enough.

GfE also doesn't pick up hot fix drivers, like Sajin stated. You have to force the driver to update.

Also, use the cable thay came with it. If it is made with it, it will work with it. "better" because you paid extra doesn't mean it will perform better all the time.

I use GFE and a Monoprice DisplayPort cable on my Swift with a 980 SC ACX 2.0. No issues at all in BF4. I have a similar system to the OP. One think, I have found is that overclocking may be a no-no and higher speed memory can be problematic.

Anyone have a link for the 355.80 download, i tried to locate it and im struggling. I am running 355.60 so i want to see if that fixes it. 

Well looks like things are stable again after the driver updated i was able to load into the game without crashes or terrible frames, i ran the benchmark and at the ultra with 2560x1440 and 144hz i averaged 80+fps. So thanks for the help today guys!!!

turn off V-sync for any games your playing g sync don't play nice with it on I had this same problem even with my older games
