The CPU is better in the new computer (Intel(R) Xeon(R) CPU E5-2690 v4
@ 2.60GHz vs Intel(R) Xeon(R) CPU E5-2680 v3 @ 2.50GHz). The caches of
the CPU are slightly bigger. The new computer has more RAM (512GB vs
128GB), and their clock speed is also higher (2400MHz vs 2133MHz). The
Nvidia Quadro P5000 has 16GB, while the other one has 8GB. Sincerely,
I don't know why it is going slower. I thought it was something
related with the program, linux distribution or driver version.

I have tested it in chimeraX and the side view is working as it should.
