DirectX releases an update like every month or so I believe, so if it's telling you to update it, then do so. You can update your DirectX by downloading the installer
Here
PCSX2 readings of CPU specs are not accurate, if you want to make sure you get the right info from your CPU, then download a program called
CPU-Z.
It won't run if I don't update DirectX. Do I have to update monthly??
nope, just when a program or another asks you to do it
I've never downloaded a DirectX update before, I use the ones that's provided in game discs. My old P4 didn't ask for any update when I first run PCSX2 either.
Every DX update contains new files in it and those new files are required by the GSdx version that you are using now.The old GSdx version that you used on your old pc needed some DX files that you already have.
To put it simply,the newest GSdx requires a file that is included in the DX update from June this year,so if you downloaded directx from earlier month than June,you wont be able to use the newest GSdx pluigin.
Updating DirectX doesn't mean updating from DX? to DX9,10 or 11
OK. Understood. Thanks. : )
