As i have no crashes or freezes to think of, i still wanted to try this to see if texture flickering or general performance issues were addressed. From what i can see, this d3d9.dll fix hindered my game performance.
I cleared the SkyrimPref to allow the game to start a new one, added the d3d and enbseries, started up the launcher, accepted the settings it defaulted to and started up the game. No change so far. If anything, after applying this, my GPU maxed out at 99%-100% no matter where i was or what was on screen, and my FPS suffered because of it
But hey if its enabling people to experience this great game and fixing the CTDs, then great work ENB!
