I don't know about that, but I've always taken the attitude if it ain't broke don't fix it, and that driver has always worked fine for me.  Newer driver releases are ALWAYS all about games, which I don't play.

There is now another type of driver, studio drivers or something like that, i downloaded the latest one like a month ago and works pretty well. This drivers do not include game related stuff, they are more about stability for people that dont necesarily game with them, but are focused more on work relyaed stuff

Where are you finding studio drivers? I checked Nvidia site and am not seeing anything with that verbiage 

I whole-heartedly agree Mike. I may try to go back to a driver from at least April and see if that can work. No reply from RL Support since the 26th. So far Reallusion just thinks I am talking about the message panel. Also no reply from my account executive at Alienware. Frustrating when I am trying to get an episode out, but it is what it is for now.

About the "Nvidia Studio" drivers...

https://www.nvidia.com/en-us/geforce/news/studio-driver/

Available today, the latest NVIDIA Studio Driver provides optimal support for the latest releases of top creative applications including Magix VEGAS Pro v17, Autodesk Arnold, Allegorithmic Substance Painter 2019.2, Blender 2.80, Cinema 4D R21, and Otoy Octane Render 2019.2.

A cool feature is 30-bit color support.  You can really see the lack of color-banding in the sunset pictures on the page I linked to.  (Simulated, so they could demonstrate what they're talking about.)

Thank you so much Raxel_67 and Justaviking! Going to check that out now and hopefully my renders will get back on track. I will update once I know more! Thank you again! 

I did a clean install on the Studio Drivers but that did not help that weird "gridding" that is happening in the hair now. Hopefully Reallusion support will see something in my system report. 

Are you on windows 7 by any chance? It is known for having issues with opacity

What I have gathered from the screenshot, those are common hair opacity artifacts. It seems they never go completely away regardless. From personal experience,  upgrading from win 7 to win 10 in the past (and directx respectively) made things look a little better. But still, those artifacts are popping up every once in a while. The only way to fight them is to render with smaller view-port window. You have to experiment, gradually decreasing view-port size and rendering until artifacts are gone. You would loose the render speed and possibly some qualify. But that is a trade-off.
