Hopefully this will finally fix the weird desktop zooming issues in Windows 8.1.
 
326.19 was terrible for surround/sli under Win8, hopefully these improve things.
 
These are rocking for me (with an X-Star DP2710 @ 110hz 2560x1440)... much better and consistent GPU utilization and better performance in BF3 and Dirt Showdown for me. I'll have to run some framerate logs soon...
 
Well these ones still suck for surround in Win8, love watching my menus jump all over the screen for no reason.
 
Getting very low fps with these drivers in GRID2. Specs in signature. Anyone else having this issue?

Rolling back to 326.19 fixes the issue and none of the settings in-game have changed from Ultra with Soft Ambient Occlusion on. SLI is turned on each time, of course.

I'll try Grid 2 with my Tri Sli 780s and report back

Single or SLI? Havent heard of SLI works on the korean monitors with these new drivers yet....Im still stuck with the 780 launch drivers..bleh
 
My Galaxy 780 was being somewhat unstable after a few hours of uptime with 320.49, it would randomly crash afterburner/precision/xtreme tuner, had some hiccups on video playback and in games as well. It even blue-screened during the install of the 326.41 driver.

Thankfully I haven't seen these problems with 326.41 yet! Left it on overnight and afterburner was still running this morning. Hadn't been able to get that to happen since I installed this card.
 
Same instability as 320.49 with my GTX 560 Ti (single). Random "driver has crashed" errors in Windows Explorer, but never in actual games. Piece of shit.

Were you able to check the performance out? I'm also having problems with Far Cry 3. It's like the SLI profiles for those games were borked. Had to change the SLI bits with Inspector to get the performance back for FC3. GRID 2, I didn't bother since I rolled back before trying to manually fix that.
 
I loaded these up on my son's machine, and it caused displayport to no longer function in Windows. I had to rollback to 320.18 to get it to work again. This is a Evga GTX680 and an Asus VG248QE. Anyone else experience this or aware of an ongoing issue?

Thanks!
 
Using DP on Win8 on a Asus Rampage IV Formula without any issues on these drivers. Gave me a nice boost in games compared to 326.19
 
solid drivers as usual for me. been using since they came out, not one single driver crash

leave your system on for ~36 hours then see if you can repeat that statement pls.

QFT. While the last beta release may have been stable in games, I'll get random hardlocks with the system in sig. Just because it looks like a duck, doesn't mean it's not a donkey instead.

I'm going to install these and try them out and report back.
 
I seem to be facing a no video signal issue.

Sometimes when a game is set to run at a different resolution, the video output gets cut when I close that application. For instance, I play CSGO at 1024x768, and when I quit the game, the monitor loses all input.

Currently connected using a DVI-VGA cable with my GTX460.

1024x768 on [H] with a GTX460? GTFO.
