Yes, at least if you mean this thread: https://forums.ashesofthesingularity.com/486449/ashes-support-faq#videoissues
I did not see anything about re-installing video drivers there, though. Anyway, I have tested a slew of different configurations now, Ashes: Escalation v2.9 (via the Steam Beta option) and v3.0, combined with older Nvidia driver from 2019 and newest Nvidia driver, combined with different graphics presets and graphics interfaces (DX11, DX12, Vulkan), fullscreen or windowed, with or without VSync ... you name it.
Apart from benchmark results in the 1-2 FPS range the only other consistent observation I made is that neither graphics card nor CPU showed any kind of load during the benchmarks. What I expected to happen is that the fans would engage and the notebook would get warm during the benchmark -- not the case. I did the last benchmark runs having the task manager open in the background for confirmation and as I suspected, there was only a light CPU load (~30%) and no visible load whatsoever on either of the two GPUs (dedicated or embedded, the latter should not have been used anyway, of course).
Since I could find some rather recent benchmark results of the 2070 Max-Q (2019 or so) on the internet for Ashes: Classic I then decided to download that from Steam and give it a spin instead of Escalation. And, lo and behold, 70ish FPS on High presets with the current Nividia drivers and DX12 right off the bat. Did not even have to tell Windows explicitly to use the dedicated GPU. And also the fans decided to turn on in hoover mode.

So, I do not really know what to take away from this. Seems like this is not something that cropped up with the 3.0 version, nor does it seem directly driver or configuration related. More like some change that happened sometime in Escalation as opposed to Classic?
I can provide a ton of benchmark results now, if that helps pinning it down. Also happy to do further tests. Would really like to be able to play Ashes: Escalation 
Thanks!
