This issue is related to the following github issue (<a href="https://github.com/bulletphysics/bullet3/issues/1545" class="postlink">https://github.com/bulletphysics/bullet3/issues/1545</a>).<br><br>I am using a Nvidia Quadro K6000 GPU (12GB) with Ubuntu 16.04 and python 2.7.12. I am having a problem in achieving high FPS (the link given to the github issue was answered by Erwin in which he achieved 280 FPS with GTX 1080) with my computer. I have installed pybullet using pip and the attached code (shared in the github issue as well) can be used to measure the average FPS.<br><br>I am attaching the text file output of the code. I am getting a <strong class="text-strong">30 FPS</strong> output when averaged over 100 iterations, which is almost the same as I am getting on a non-GPU system. In addition, I am attaching the .json performance logger file which shows the time taken for individual processes (can be viewed in chrome browser using about://tracing) while running this code. Here, as also mentioned in the github issue #1545 rendering the image only takes microseconds (260 microseconds in my case) while most of the time is spent in waiting for the image (from #1545: "Note that very little time is currently spend in rendering (less than 200 microseconds on my 1080), it is mainly copying data / waiting that makes is several milliseconds."). I am attaching a screenshot as well for further reference.<br><br>I am planning to shift my Deep RL simulation from gazebo to pybullet as the latter is much more flexible and coder friendly  <img class="smilies" src="https://pybullet.org/Bullet/phpBB3/images/smilies/icon_lol.gif" width="15" height="15" alt=":lol:" title="Laughing"> . I am also interested to know if pybullet is not the correct SDK for using bullet physics engine for RL research is there any python/C++ based tool which has a well established GPU support system? Any help at all would be appreciated thanks!!!<dl class="file"><dt class="attach-image"><img src="https://pybullet.org/Bullet/phpBB3/download/file.php?id=1744" class="postimage" alt="performance_logging_rendertest.png" onclick="viewableArea(this);" /></dt></dl><br /><dl class="file"><dt><span class="imageset icon_topic_attach"></span> <a class="postlink" href="https://pybullet.org/Bullet/phpBB3/download/file.php?id=1743">renderTimings_mingui_json.tar.gz</a></dt></dl><br /><dl class="file"><dt><span class="imageset icon_topic_attach"></span> <a class="postlink" href="https://pybullet.org/Bullet/phpBB3/download/file.php?id=1742">output_rendertest.txt</a></dt></dl><p>Statistics: Posted by <a href="https://pybullet.org/Bullet/phpBB3/memberlist.php?mode=viewprofile&amp;u=13370">rkartik27</a> — Mon Aug 12, 2019 11:55 am</p><hr />
