The issue is that at times I found myself not getting center scaling in Vantage, 3DMark06, Crysis, etc. So I know it didn't work even though I went through the process of making sure it's enabled. So, I too am providing my experience. It's not to imply anything towards you. What you replied to was me saying that you have to check the feature every new cat just to see if it's still working. If you stop being so defensive about it you would understand my issue was before 10.3. Had you just taken my experience for what it was you would see I never provided any specific dates or cat releases.
