FPS drop with SLI Enabled? higher FPS with SLI Disabled

I am quite new to SLI.

 

I have a Philips 4K screen 288P6 set on Display port 1.2 to get 60Hz.

My PC spec atm:

 

Mobo: Asus Z77V-PRO

PSU: Coolermaster 850W

CPU: i5 3570

GPU: GTX980 SLI x2

RAM: 16GB @ 1333MHZ 

OS: WIndows 8.1

Nvidia Driver: 350.12 (GTA Ready)

 

And when I go to Nvidia Control Panel>manage 3D settings to enable my SLI

I get a huge frame drop in GTA 5 to 20-30fps.

When I disable the SLI in the Nvidia Control Panel

I average around 40-50fps in GTA 5

 

My GTA 5 setting is everything VERY HIGH  

It is using around 3600MB on my 4000MB (orange bar in GTA GRaphics menu)

VSync on

MXAA off

TXAA off

FXAA on

 

What I don't understand is why would I get more fps with SLI off?

What else should I be checking? Please advise :'(

Maybe it doesn't support SLI? Yet?

The time you enjoy wasting, is not wasted time.

SLI SCALING FAILURE. 

“When life gives you lemons, don’t make lemonade. Make life take the lemons back! Get mad! I don’t want your damn lemons, what the hell am I supposed to do with these? Demand to see life’s manager! Make life rue the day it thought it could give Cave Johnson lemons! Do you know who I am? I’m the man who’s gonna burn your house down! With the lemons! I’m gonna get my engineers to invent a combustible lemon that burns your house down!”

Did you download the newest drivers?

The game already supports both SLI and CrossFire

Must be a driver issue, the SLI scaling on gta 5 is actually pretty good.

Those are the latest drivers, at least he has it. I have been trying for days to get my Nvidia drivers to uninstall and install but to no avail. Even support can't find a solution. It should probably be fixed in a game update.

Supports and works are two different things...

 

People have had varying experiences with SLI it seems so you will have to use one card until it is patched or updated.

Well, CrossFire has worked amazingly for me, so that at least works

I have heard of bad experiences with 970s and some 980s.

 

Total Biscuit had an okay experience and so did you apparently.
