Installed the new drivers last night, and got around 5fps increase from the previous whql drivers. I've also just spent the last couple of hours playing around with the adaptive v-sync settings.
My specs:
i3 2120 3.3GHz
GTX 550 Ti OC'd to 950/1900
4GB ram
Normally I average 50-60 fps @1920x1080 on Ultra High settings on, but with AA set to 2x. I also have the Hi-res DLC installed, and the only mods I use are the Hi-res DLC fix and the Unofficial Skyrim Patch. I use MSI Afterburner to limit my framerate to 60, and D3DOverrider's Triple Buffering. With those settings, the gameplay is fluid, no stuttering or 64Hz bug hitching.
To test, I turned off the Afterburner frame limit and D3DOverrider, and set the Nvidia Control Panel to Adaptive. The framerate stays around the same, maybe a couple of FPS higher, but as soon as it drops below 60 I get massive screen tearing. This, I guess, is to be expected, as the v-sync is only enabled when at the screen's refresh rate (60Hz) and disabled when below that rate. I also seemed to be getting the 64Hz bug again, so I limited the frame rate to 60 in Afterburner and turned on D3DO TB and the 64Hz bug is gone, but of course I'm still getting screen tearing when the frame rate drops below the magical 60fps.
There's also an option for Adaptive v-sync at half refresh rate - on this setting I still get some screen tearing, but you really have to be trying! I guess this is because it's vsync locked to 30fps which my system can cope with without dropping frames unless it's REALLY pushed. No 64Hz obviously because it's frame rate is limited under 60Hz.
I've basically ended up turning everything back to my old standard settings - Control Panel back to "use app settings" on v-sync, D3DO's TB and Afterburner limiting FPS to 60. I hate screen tearing, it gives me a headache just thinking about it! I know others aren't as susceptible to screen tearing as I am, so it may be worth a go to see if it's acceptable for you, as there is definitely a coupla FPS increase using adaptive.
Hope this is of help to someone!
