I tried posting about this in the dedicated driver thread, but no replies yet. I also see that this hasn't really gotten any attention elsewhere. At least not that I've seen.
Since downloading the 511.23 driver, I have noticed general weirdness with my 3090 and my previously stable undervolt settings. My every day settings for gaming were at 975 mV on the core with the core clock target set at one step above 1800 mHz.
I was running these settings for basically an entire year straight with zero issues, across multiple titles. Even titles with DLSS and RTX On (like Control).
I installed the 511.23 driver branch and now I'm getting all sorts of weirdness. Crashes in Control where I never had any issues before was the most drastic change. I have to run my GPU at utterly stock settings in order to run the game now.
Other titles will just randomly crap out while I'm playing - it's like the driver just takes a dump and either results in a freeze or the application will just close entirely. I ended up having to bring my core voltage up a bit in order to compensate. I find this kind of annoying, because with the settings I had in place before, my GPU was generating much less heat and the temps were cooler too. It's not a huge difference in temperature metrics and whatnot, but I do definitely notice the seemingly new instability at lower core voltages.
Has anyone else experienced similar weirdness on the new drivers?

I have been playing all games (including Control, Cyberpunk, GoW)1950mhz @ 950mv + 1000 mem for several months now on 3080ti and haven't noticed any new issues. Have you tried uninstalling and re-installing your driver? Sorry friend, my reply really doesn't help much but perhaps others are having issues.

Haven’t had time to do a full DDU wipe and whatnot yet. Planning to tonight. I assume you are running 511.23? What method do you use to undervolt? I have seen multiple tutorials and they all seem to have conflicting instructions to some degree. Most of them result in just locking clocks at a particular voltage. Which in my mind, isn’t really accomplishing what it’s supposed to.

By definition, undervolting is less stable in general.
If it appears to you as a driver-specific stability thing, I would conclude the specific driver is more performance-optimised for whatever workload you are giving it, and therefore even more able to push your performance into unstable territory.

Probably just needs DDU done and a clean install.

It’s possible degradation is starting and now requires more voltage to be stable at the same speed. After all, its stock voltage is just that for a reason, and the GPU may run just fine with it for a while longer. It really depends on much you use it. However, it’d be awfully coincidental presenting itself right after installing a new driver. Like it’s been said already, try DDU and undervolting again.

Yes, general weirdness , I might try a DDU today too.

As everyone already suggested, a DDU uninstall may be in order here. I had some strange issues on my undervolted 3080 after updating to 511.23 and a fresh Windows install seems to have fixed it. I'm assuming it was the clean install of a new driver that did it.

Planning on doing a DDU with clean install tonight and will report back. Thanks for the feedback.

I have seen multiple tutorials and they all seem to have conflicting instructions to some degree. Most of them result in just locking clocks at a particular voltage. Which in my mind, isn’t really accomplishing what it’s supposed to. I hope that the DDU works for you and gets you all straightened out. Yea I'm using 511.23 and the first time I undervolted I just used the stock curve, bumped up the 950mv point to 1950mhz, lowered the rest of the curve and hit apply. This method worked and my card ran fine. However, my only issue with this method is that my card would constantly sit at 1950mhz and 950mv. I didn't like that so instead I set everything to default, bumped up the core to +120 or so hit apply and then found the 950mv point and lowered everything else. This allows my card to sit idle at 210mhz and speed up when under load. I prefer this method and haven't had any issues. Take care!

removed some simple things and no more weirdness , reboot
Undervolt rules just like it should, just got an FE 3090 PR score at 318w
