When lowering resolution it soften edges

I know there is an anti aliasing button you can turn off and it will sharpen the edges, if you stick to 1280x720 resolution.

The issue is when I use 640x460 it blurs the edges slightly. I would like for it to be rendered sharply like a point rendering.

Is there a way? or feature?

I think what’s happening is that the browser has the anti aliasing on and when zooming it it’s doing this. Here is a screenshot of what I got.

And here is an example of me zooming in within the browser and it keeps some shapes sharp and others blurred. I think this is because some may be vector based and others are pixel based.
