Precision X1 is in the title, and the main post. Precision X1 has only been available for 3 months.
Afterburner has also been in Beta since RTX cards released, 3 months ago.
Unwinder builds afterburner for MSI. Unwinder also use to build Precision, up to version 4.2.1, and had a lot of experience working with all of the systems. Unwinder continues to build on the software that he has established years ago, and improve on it.
EVGA started building Precision XOC starting with the 980 launch. When they released 5.0, they were called out for using unwinders code, which they had paid for, so they pulled 5.0 off the download list, and build precision XOC 6.0 from scratch. Yes, there were issues, because EVGA does NOT, believe it or not, have access to every single build available to the public. To have access, they need to have users report their issues back, because otherwise they would never know what issues were out there.
Starting with the RTX launch, EVGA released another new software, Precision X1. Precision X1 was also built from scratch, not using coding from the older Precision XOC.
I know very little about programming, but I would assume that it is not an easy task to figure out what every single person using the software is using, and know how to remove the issues. With Precision X1, EVGA has been pushing updates much faster than before.
If you like Afterburner more, use it. There is nothing wrong with using the software that was established many years ago, and maintains the same features it has always had. I use afterburner, and it works great, but I also do not utilize an EVGA gpu that requires Precision X1 or Precision XOC. Afterburner is very plain, and just works.
