I installed this driver when GeForce experience said i had an driver update ready to download and all of my setting in the Control Panel have been the same as previous drivers and this is what is happening to me with this 344.75 driver since i installed it in tuesday 18.11.2014.....
Good

1. all game play is still smooth. No stuttering or FPS drops of any kind
2. No system crashes

Bad

1. VLC randomly freezes and crashes
2. Windows Freecell also freezes

 

Installed my new EVGA GTX 970 FTW yesterday morning, replacing a GTX 770 card.
 
To be safe I uninstalled my previous drivers with DDU in safe mode, shut the computer down, installed the new card, and then did a clean install of these drivers ( only graphics and PhysX).
So far running very well for me.
 

I never had a problem swaping cards while having the same driver installed, done it many times
 
its only if changing from Nvidia to AMD that problems would arrise, but if swapping a AMD with another AMD or an Nvidia with another Nvidia it will be fine.

Myself, and probably many other people have had problems doing that. Your way is not a blanket rule to all people.

I still think the best driver for my GTX 970 is 344.16  :)

sorry... wrong post
 

I just tried out these drivers, and good lord the SLI profile is horrific.  With three cards, I get all sorts of flashing and color changes when trying to test an overclock with any OC Scanner option.  I switched back to 340.52 and it is pristine with the Sli profile.  I am going to try downloading all of the drivers inbetween those two and see where the issue starts.
 
All 344.xx Drivers have this error.  I have installed everything post 340.52 and it is just craziness when running anything.  Going to try BF4 now, and see if I can get back to the "Normal" FPS that I was seeing before.  
 
with 344.xx drivers, I was getting 90 - 130fps with fluctations (that I noticed) and with the not I am getting 120-160 with 340.52.   I dont think my GPU's like the 344.xx SLI profile at all.

Game is set to Ultra with 150% resolution scaling. Playing at 1080p single monitor.

Thanks for that tidbit, I am still on Driver 344.16 I may give 340.52 a test run on my 980's if I can?
For me no driver after 344.16 would at all or well in 2-Way SLI or 3-Way SLI.

 After a couple of hours playing BF4 with this driver tonight, the screen would flicker until I did ctrl-alt-del then went back in the game it went away. It comes back again after a few minutes. Anyone else have this problem?

Not specifically this game, but I had similar results in Far Cry 4 and BF4

I tested the 344.75 vs the 347.09 as Scarlet did in his video. The 344.75's were terrible during testing any benchmark, probably enough to give you a seizure if your prone to that. Although they ran cooler (980's SLI on air) the flashing and flickering were terrible. I moved up to the 347.09 and benching runs well, but they run "warmer" depending on benchmark (warmer= ~2-4*c)  Benches and games run better on the .09  so I left them on that. 
 

You would be better off using the 347.09 WHQL drivers that are out.

While playing BF4 I've been blue screening with the new drivers and DSR on.
