Permormance doesn't match description

[bedbad]

Performance with accuracy doesn't match description:

Steps to reproduce:
Follow exact steps of getting started except:

• adjusting the device to 'mps'(apple m1 processor, 3-5x performance increase from 'cpu')/'cpu'/
  meaining if 'cpu' is set the performance is at least 2-3 times lower.
• fixing the opencv geometry drawing functions by casting points to tuple of int instead of tuples of float as in master branch(opencv drawing methods only draw on integral type locations)

Results:

FPS degradation from 30FPS to 15-25FPS and, most importantly, which as far as I understand can not account for use of device as it supposed to run mobile the fitting is poor.
