Anti-aliasing

I have just moved up from an ATI Radeon x800gto VGA to MSI Nvidea 8600gts and this has introduced me to simple OC experimentation but I seem to make things worse if I enable any of the Anti-Alias settings which are Off by default! Just what does this do and surely it should improve things shouldn't it?
I have since discovered an A-A enable/disable in the display settings of my Flight Simulator, and enabling that makes it worse also! With all the hype on the box about the (n)times A-A just when do you use it?
Thanks.

Hi, in my understanding, AA takes away the 'jaggies' making text edges smooth. In images it can create a halo effect around some objects, it also makes an image appear larger due to the fact that AA also increases the amount of colour pixels - probably why images appear less clear.

When to use AA, hmm, not so easy, I guess that would be down to individual preferences. Perhaps someone else can give a better explanation. But I hope this helps.

BTW, in FSX I find it looks much better with AA 'switched' on as in this screen grab ..

Hi. I have just given my FS9 a bash again and you are right - with it enabled it is much better - but - I have also been tweaking elsewhere so it's not conclusive...
Guess it's just because Lara doesn't look so sexy in the Anniversary demo since I first downloaded it, it's the halo/soft edgey thing around her shoulders and legs :-)
Your post did help Techno, and I am still experimenting. I was hoping for a quick answer as resetting/reloading everything just to check a small setting change is a bit tedious and having to take screenies to double check makes it very laborious indeed.
If anyone runs this game I would be happy to know what settings they use but I realise both rigs and personal preferences differ widely.
Cheers.

smoothing out jagged edges takes graphical power, you would probably need a 8800 series card to get decent framerates with aa on.

I have a G6600, no problem at all with AA on. FSX(DeLuxe) looks much better with it on.

My FS9 is really brill now but no plans to go FSX just yet (bit put off by the little wheatabix box cut-out vehicles ;-), but probably later).
I am also playing with the OC features quite a bit, just testing for experience really as not had the chance before. My mobo will OC as well but I haven't tried that yet. I am running a CRT ViewSonic UltraBrite E96f+ on 12x10 although it will handle higher. It gives a good account of itself but I think a TFT would be better suited.
I don't want to turn this into an OC thread but my bog mobo/vga benchmark 10726 with everything else running in the background, so I reckon there is room for improvement.
I will continue experimenting with the A-A features as I have found that the GTR2 demo crashes if I set Full Screen A-A so it's just a question of getting used to all the settings.
Thanks for the feedback and I don't fancy Lara Croft enough to fork out on an 8800 but another 8600GTS will be in the stocking next month for SLI config :-)
Thanks again.

OK, thanks for the feedback. Cheers.
