Description

Hello,

i am experiencing quite the performance gap between the compiled simulate.cc GUI and the viewer application.
I made i quick video of the issue (https://drive.google.com/file/d/1zT55YzBXGRdBOVW2JMWQVyoJtmYLpZf3/view?usp=sharing).

My system is an Thinkpad x1 yoga gen 6 (i7 1165, 32gb Ram) running Ubuntu 20 LTS.
I do not experience this gap on my private pc, a Macbook Air M1. It runs just fine there.

The simulated .xml File is the following and a tiny torque is applied to break the stable pose.
