I wanted to see whether the Quality setting in fsx.cfg worked and/or whether I could enhance the 4x AA to be the 4xEQ AMD EQAA Mode
From the only AMD spec I can find for the 6700 I suspect that the quality setting is 8-15 (but its only a guess)
Default DX 10 4x MSAA
Look along the top of the pink car.
DX 10 4x with MultiSampleQuality =15
Compare the pink car with above – the gradations are finer. Mind you it didn’t look any better to me on my monitor!
DX 10 Default (4x) Enhance Application Settings x2EQ
I claim that the same as above. So it looks like both the quality setting and the enhance option do something over 4x default.
