Thanks for your extended tests (it would have been even better for the Forum visitors, if you would have put them all into the same post).
What is your conclusion regarding the result of your various benchmark tests?
Fernando, I have tried installing the modded generic Samsung NVME driver for my 990 Pro.
The results are tremendous, crystalbenchmark RND4K Q32T16 is a lot better and I get +50 AVG fps in CS2.
However, whenever I restart the system it fails to boot and keeps spinning on the motherboard screen, resulting in me having to repair the system.
This in turn resets the NVME controller back to the Windows 10 standard microsoft ones.
Have you heard of this issue before and is there a fix?
I have installed the certificate accordingly beforehand.
Thanks!

Welcome to the Win-Raid Forum and thanks for your input!
No, I didnāt have such problem and never heard about it.
You can try to solve this problem by forcing the installation of the original WHQL signed Samsung NVMe driver (you have to use the āHave Diskā button and to navigate to the related original driver folder). Although the HardwareIDs of your on-board NVMe Controller is natively not supported by the original driver, it will work flawlesssly and the WHQL stamp will be shown by the Device Manager. I have tried it very often successfully.
Good luck!
I tried the Phison driver and it also didnt work. Same endless spinning on MOBO screen and startup repair defaults back to the standard NVME drivers. Only the standard NVME driver seems to work. Iām on W10 and AMD 5800x3D, I donāt seem to have this āHave Diskā button available when updating the drivers 
Edit: I found the Have disk Button, going to attempt it now.
Yes! You will get a warning, that the driver may not work with your NVMe Controller, but it definitely does.
