Please explain the extended parameters of graphics

BlitzMax Forums/BlitzMax Beginners Area/Please explain the extended parameters of graphics

Dear community,

I don't really understand the very brief documentation of Graphics()

What is hardsync? what is softsync? what goes on under the hood? is the monitor refresh rate actually ever changed?

What happens if I specify -1|HARDSYNC? will this change the monitor's refresh rate from 60hz?

I get a headache from crt monitors at 60hz really quickly.
