Hi, this article: http://msdn.microsoft.com/library/default.asp?url=/library/en-us/directx9_c/directx/graphics/TutorialsAndSamples/Samples/Antialias.asp describes how Direct3Ds multisampling works. During Device Creation u have to pass two multisampling related values to the constructor (i took the managed values, but the values for an unmanged app are similar): MultiSampleType MultiSample int MultiSampleQuality but what do these 2 values exactly mean (the explation in the msdn is a joke). Does MultiSampleType.TenSamples for example mean, that Direct3D uses 10 Sampling Points per Pixel? And what does MultiSampleQuality exactly mean? thx for your help

I think some of those values are somewhat subjective per hardware device. Each manufacturer has their own way of implementing AA, with varying degrees of quality and similarity. In short, the rasterization rules for AA aren't set in stone, and these numbers are mostly hints on how good it should be. That said, the numbers do mean something: The more samples you specify, the more frame and processing will be taken. More details are probably available on ATI and NVidia's developer sites.
