updating to OpenGL 3.2 from OpenGL 2.1
<p>I am trying to install obs-studio <a href="https://obsproject.com/" rel="nofollow noreferrer">https://obsproject.com/</a> on arch linux but its documentation says </p>

<blockquote>
  <p>Linux</p>
  
  <p>NOTE: OpenGL 3.2 or later is required to use OBS Multiplatform on
  Linux. You can check what version of OpenGL is supported by your
  system by typing the following into the terminal:</p>

<pre><code>glxinfo | grep "OpenGL"
</code></pre>

<p>so my system output for </p>

<pre><code>glxinfo | grep "OpenGL"

<p>it says <code>2.1</code> so how could i upgrade it to <code>3.2</code></p>

<p>as from arch inux documentation <a href="https://wiki.archlinux.org/index.php/intel_graphics" rel="nofollow noreferrer">https://wiki.archlinux.org/index.php/intel_graphics</a>  i have already installed <code>mesa-libgl</code> ,  <code>xf86-video-intel</code> package.</p>

<p>result from chrome://gpu/</p>

<p>i see that <code>In-process GPU    false</code>  does this means i have to buy a external gpu</p>
