How would you go about simplifying this geometry?
(Some more info: I wouldn't really be worried about it but at the moment it takes ages to render in cycles and I think it may be because of the amount of verts in the scene?)

$\begingroup$ PS. They are many more blocks like this (it's a simple building placement scene), I have considered replacing them with new geometry, but think that may take a while. $\endgroup$– DanSep 29, 2015 at 5:21

$\begingroup$ It's probably not the vert count that is slowing down a cycles render unless building the BVH is taking a long time $\endgroup$– Tim BahrijSep 29, 2015 at 11:17

2$\begingroup$ BVH is how cycles loads all the geometry in the scene when you hit the render button. If you have a lot of geometry (2million verts +) building the BVH and getting it ready to render will take a bit longer than normal. Because the way cycles works, mesh density doesn't have too much of an effect on render time. Things like lots of bouncing lights (an interior scene, like from sunlight bouncing off the ground outside, in through the window, then around the room for example) will slow it down tremendously. $\endgroup$– Tim BahrijSep 29, 2015 at 13:04

It is in fact really easy. Select all the geometry of the object with too many vertices in edit mode by pressing A. Press delete or X, depending on which you prefer, and click limited dissolve.
After that, your mesh will look clean.

1$\begingroup$ Thanks for this. 99% of the time decimate gets recommended even when people explicitly ask for a non lossy reduction. $\endgroup$ Oct 29, 2018 at 13:48
