It’s important because now you can take full control of stats that you weren’t able to because of the lock.
And it migh be good for linux because since the 900 series gpu, or since the lock were first implemented, the open source nvidia driver it’s not able to re-clock the gpu with an higher clock than the boot one (and trust me it’s a really low clock) and you are not able to use a quarter of the power the gpu has.
Even if the open source driver code is 100% equals the nvidia one, literally copy pasted, it would not work because it need to be signed by nvidia to do so.
