#11
Why I mentioned earlier about the uninstall of DirectX. I knew you couldn't just install an older version, you'll have to root out every trace of 11 and then there would be no guarantee that you could install an older version or even that it wouldn't mess up your system totally. I don't remember where I read the steps to uninstall or I'd link it for you, sorry.
Only reason I can come up with about the "why" you asked is...... just different versions written different ways.
Maybe a driver/firmware rollback for your GPU? I'd be mighty careful there..... have you gone to the new gpu's maker and asked there?
