No, no real updates.
I'm not on 182.50 anymore. When Windows alerts me of updates, I usually just click to apply them, since it's often just Windows Defender updates. A WDDM driver update slipped past me one time (this was probably about almost a month ago by now), and once I noticed it, I decided to just let it go. The control panel claims it's version 190.38, and there's new 195.xx beta drivers that nVidia is releasing due to the now current latest (191.xx) official ones having known issues with The Sims 3, which I play alot, so I'll grab those when they release.
For now, I'm living with 85Hz (KrossX, it's known that all driver versions after 182.50 can't go higher than 85Hz), although my 1400x1050 resolution is at 100Hz, since I created it while I was still on 182.50, but I had all of my other resolutions set to 100Hz, yet they fell back to 85Hz, sometimes even 75Hz. That's odd. I wonder if it's because I actually created 1400x1050, but I am using 100Hz on a resolution past 182.50. It's just that I can't get it on the others.
As for the the interpolation, it still happens, but I've created custom resolutions for the resolutions I use, and used custom timings (via CVT I think it was?).
In other words, 85Hz is acceptable (but the minimum) for me, and so long as I can override the interpolation happening, I'll have to live with it, I guess. I don't have a choice, maybe save moving to ATi. I'm not holding my breath for a fix, though I'd like to be surprised, but I can't stay on 182.50 forever (new games, and once I upgrade, won't allow that).
