I just downloaded and installed Chrome 46.0.2490.64 beta (was on Chrome 45 Stable). Well not impressed to be fair. My memory usage is only around 200-300MB less, not exactly that much improved as it was claimed, for me anyway. But it's beta and will stay on the Beta channel and monitor my memory usage over next few releases. Some claims of it dropping by half but not for me as of yet, obviously everyone has their browsers setup differently, addons, themes, apps etc so that will have a major impact I guess.
Google suppose to be working on the memory leaks, graphics performance so hopefully that will continue.
