Steps to reproduce
Expected: Both SVG images are similar clarity
Actual: Top SVG image is blurry
Read http://benfrain.com/svg-backgrounds-dont-zoom-correctly-in-internet-explorer-10/ for a full rundown. This is still a bug in IE11.

Subject: RE: SVG backgrounds and optical zoom
We should open a new bug. This is “by design,” but I think we could do better. There are many cases where IE rasterizes SVG content. This has become a real problem with multithreaded rendering. It takes up to 3 paints to rasterize SVG content. This causes flicker and prevents animation.
Instead of rasterizing a bitmap, we should treat these scenarios like a special case of the use element. This solution should fix this issue, eliminate the multi-paint requirement, and also fix the following similar bugs:
591262 SVG Backgrounds results in 2 rasterizations rather than 1
142449 Nested SVG filters produce an incorrect result
18626 SVG Filter output clipped when source primitive is not in the viewport.
Of course, this would require a considerable amount of investment.
