Resolution of 1280x1024. No AA. You can never get rid of jaggies. Even at 1600x1200 and 6xAA, I could still spot jaggies. The only remedy is High Res. It's a nice workaround however.
AF isn't a workaround, but a way of doing things properly such as trilinear is better than bilinear because trilinear does the same thing without artifacts. AF cleans up some artifacts.
But sometimes performance is really low and I'm able to live without it. I've lived since 2000 without AA and AF until I got a 5900. Then everything suddenly changed and I was able to use it, but still it hurts performance and it makes cards last less as long. I don't want variable settings. It's weird with me because it's either this or not and no in between so, it makes things a bit complicated.
Plus I like high fps. I don't want to play at 30fps with high AA and AF. I don't require those. They are nice to have however. I do require Trilinear to be something for a card to do with very little performance hit.
