What I mean is that I want that you can set that the whole image gets rendered in a higher resolution than your monitor and gets downscaled to your monitors resolution again. This would be useful cause many old games don't have an anti aliasing option,but when the image gets rendered in a higher resolution and then gets downscaled,then it would be good anti aliasing. I know that 2d elements will look worse,but edges of 3d objects will look so much better.
You already filed a bug report about it and we said no. Stop intentionally filing duplicate bug reports; it's annoying.
