So while it definetely placed some new Nvidia extensions in there, I can't quantify what changed.
OG extension viewer lists same support and tests are within 3%.
Tried DOom 3 before and after too, it went from 109fps to 110fps. (everything maxed out on 30"). So, likely in realm of statistical accuracy.
But extensions MUCH newer, and there is even a NEW one, just called GeForce.
I am more concerned with precedent. Always before you had latest drivers in OS. Is Nvidia so frustrated with Apple that they are releasing separately? Do we really want an era when we have to constantly check to see which driver works in which OS and which one has what bugs in which apps?
