Hi,
If it helps I have been using this technique for a while and I haven't any
negative comments about this. But I recommend not just offering this option
unless you are sure about your texture requirements (which can be hard
within a DX layer), as when I offered all levels, users just select the top
and then complain performance or sometimes get blank screens, and not
realize that how much VRAM is eaten by this FSAA option.
I also do a check for PCI/AGP installations and then make an assumption on
this for texture upload speed which might right or wrong but so far so good,
maybe somebody else has a view on this.
Hope this helps
Thanks
Mark.
