Gave this driver a try and I am not impressed. I game at 60 hertz and while I keep at 60 FPS there is a stutter with this driver. Going back to 337.88. If anyone else tries this driver please give some feedback.

well i tried it and it really messed my system up does not work with gpu tweak and caused my system to freeze had to restore from backup.

I've also tried this driver couldn't make far cry 3 play for long freezes after like 15 mins of game play went back to 337.88 and game freezes are gone..

Yep, best to avoid this one - core clock can't be overclocked, I downloaded it because inside release notes Watch Dogs is listed with SLI profile updated (it's not mentioned on site) and after starting the game I was quite happy with less stutter but then I realised SLI was disabled after clean install 😉 With enabled it's still stutter fest, I don't know, I expected something better from Ubi, their reaction is really slow.

well i tried the driver one more time with afterburner it worked ok until i rebooted then afterburner crashed so i went back to 337.88 and gpu tweak all good again.

had some serious issues with 340.43 Driver and solved it (but not as expected) as follows:

System Specs:
- i7 4960X @Stock, @4.5 GHz and 4.6 GHz tested, under water
- ASUS Rampage IV Extreme
- GTX TITAN Black 3 way SLI under water
- 32 GB Corsair Dominator Platinum 1866
- 1200W Seasonic 80+ Platinum PSU
- 3x 250 GB Samsung 840 Evo RAID 0, 2x Seagate 2TB Barracuda RAID 1
- Windows 8.1 Pro

Error Description:
- random crashes and freezes ingame when SLI is enabled and framerate unlocked
- seemed related to high power draw/usage of the GPU's
- games just stopped responding, but not complete, like a extreme System slowdown (movement on the Screen about every 2-3sec), Sounds are playing normal during freeze
- sometimes but rare same freeze/slowdown on Desktop or during browsing
- Windows always Points to nvlddmkm related issue, sometimes to 0xc0000005 Memory related issue

Way to Glory:
- set cpu to stock, no OC...no joy 😞
- set Memory stock...no joy 😞
- add 2. 1000W PSU to ensure optimal Power (additional PCIe Power connector allready in use)...no joy 😞
- upped PCH Voltage from 1.1 up to 1.3 in small steps...no joy 😞
- edit Registry Graphics TDR up to 60sec...no joy 😞
- tested all 3 Cards on their one with no issues...yay 🙂
- reseated all Cards...no joy 😞
- tested every Card in every Slot...no joy 😞
- swaped PCIe power connectors in every possible config...no joy 😞
- checked every device has the latest Drivers...no joy 😞
- did a clean OS install...no joy 😞
- checked CPU with IBT, AIDA, Prime95 and Memory with Memtest86...yay 🙂
- tested 2 way SLI...yay 🙂
- tested 2 way SLI and third as Physics...no joy 😞

Solution:

- uninstalled the f...... Driver, went down to 337.88...Problem solved


...just wanne leave it here for further Information.

Greets ERIU
