How to Check 3D Acceleration (FPS) in Ubuntu/Linux Mint

System, Tips Friday, November 01, 2013

<div dir="ltr" style="text-align: left;" trbidi="on">
In this guide, we will see some commands needed for checking  3D Acceleration / FPS for both Nvidia and AMD graphics cards under the following distributions: 
 
<ul style="text-align: left;">
<li>Ubuntu 13.10/13.04/12.10/12.04 or older</li>
<li>Linux Mint 15/14/13 or older</li>
</ul>
If you have more commands and tools that are not listed here, please mention them below (comment form). 
 
Getting Started 
 
First of all, install this dependency via the terminal: 
 
<blockquote class="tr_bq">
sudo apt-get install mesa-utils</blockquote>
 
Before running the commands below, make sure 3D acceleration is enabled or not by entering this command: 
 
<blockquote class="tr_bq">
/usr/lib/nux/unity_support_test -p</blockquote>
 
1. Glxinfo 
 
You can use glxinfo to check 3d acceleration and rendering. Here are some commands you need to run from the terminal: 
 
<blockquote class="tr_bq">
glxinfo -i | grep render</blockquote>
 
or 
 
<blockquote class="tr_bq">
 glxinfo -i | grep direct</blockquote>
 
or 
 
<blockquote class="tr_bq">
glxinfo -i | grep openGL</blockquote>
 
The output returned will give you information about your graphics card (AMD or Nvidia). 
 
2. Glxgears 
 
You can also use glxgears to test 3D Acceleration (FPS). Simply run this command: 
 
<blockquote class="tr_bq">
glxgears</blockquote>
 
or 
 
<blockquote class="tr_bq">
glxgears -info</blockquote>
