IRAY IN 4.20 NOT WORKING WITH RTX 3080 12GB (SOLVED)

Rendering does not work whatsoever even with the simplest object such as a lonely volleyball.

I have a i5-11600k, 32GB of RAM and a RTX3080 12GB. I have CPU fallback disabled and the GPU only enabled. I have the newest driver on it, 516.59 Studio Driver.

Here's what pops up on the log.

I've reinstalled DAZ, the drivers, everything, I don't know what to do anymore. Can't render in the scene to see it in real time nor can I render it to be saved as a picture, just a black photo.

 

 

 

EDIT:

 

 

GUYS YOU WON'T BELIEVE THE SOLUTION LMAO. I followed this advice:
#########################

So I had posted on the nVidia forums and an employee reached out to me:
The solution was to search the Windows directory for nvoptix.dll and/or
nvrtum64.dll and if I found anything outside a
Windows\System32\DriverStore folder to delete them. Sure enough I found
copies of both files under both Windows\System32 and
Windows\System32\DriverStore so I moved the ones from System32 and that
solved my issue. I hope this ends up helping somebody with the
same issue, this had me running around for quite a while to where I
thought I needed to get a better GPU.

    What driver are you using?

    The log says to update your driver.

    Where did you get the drivers, here?, https://www.nvidia.com/Download/index.aspx

    Minimum driver version is 471.41, if you are now using 516.59, try some older ones. "The latest" drivers are not guaranteed to be the best working ones.

    As I said in the post, 516.59!

    Yes I only get it from Nvidia directly, I guess I'll try some older ones... cuz for 3080 I'm at 5xx drivers!

    In which version of DS? The minimum driver version often changes when Iray is updated.
