The data is from running the &#8220;Solar System | All Planets &amp; All Moons&#8221; simulation on a 2012 MacBook Pro.<\/p>\n<p>As you can see, the physics computation by itself is heads and tails faster when run in Native mode &#8212; about 2.8 times faster, in fact. This raw difference in physics calculation speed doesn&#8217;t typically translate one-to-one for FPS (frames per second) gain, but in this instance there was still an increase of 17 FPS. This is a substantial difference which you will see and feel when using Universe Sandbox \u00b2.&nbsp;This new computation mode is essentially the only big change in this update, but we think you&#8217;ll agree that it&#8217;s a big change.<\/p>\n<p>To see how much faster it is, you can switch back to the old Managed mode in Home &gt; Settings &gt; General tab &gt; Computation Device &gt; ManagedCPU.<br \/>\nYou can also display the frames drawn per second by enabling FPS Info in Home &gt; Settings &gt; Debug tab or press Alt + F.<\/p>\n<h2>Wolf 1061<\/h2>\n<p>We&#8217;ve also added a simulation of the Wolf 1061 system, which contains a recently discovered potentially Earth-like exoplanet.&nbsp;At 14 light-years away, Wolf 1061c&nbsp;is the closest potentially habitable planet ever discovered.<\/p>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"alignnone size-large wp-image-1687\" alt=\"Universe Sandbox \u00b2 - Wolf 1061\" src=\"https:\/\/universesandbox.com\/blog\/wp-content\/uploads\/2015\/12\/Universe-Sandbox-\u00b2-Wolf-1061-650x365.jpg\" width=\"650\" height=\"365\" srcset=\"https:\/\/universesandbox.com\/blog\/wp-content\/uploads\/2015\/12\/Universe-Sandbox-\u00b2-Wolf-1061-650x365.jpg 650w, https:\/\/universesandbox.com\/blog\/wp-content\/uploads\/2015\/12\/Universe-Sandbox-\u00b2-Wolf-1061-300x168.jpg 300w, https:\/\/universesandbox.com\/blog\/wp-content\/uploads\/2015\/12\/Universe-Sandbox-\u00b2-Wolf-1061.jpg 1280w\" sizes=\"auto, (max-width: 650px) 100vw, 650px\" \/><\/p>\n<p>Maybe you&#8217;ve seen an image like the one above going around the internet.
