Subpixel rendering grating stimuli with offset

Hello everybody!

OS: Win 10
PsychoPy version : PsychoPy 2021.1.4
Standard Standalone? (y/n) If not then what?: yes
What are you trying to achieve?:
In my experiment I use grating/bar stimuli with very small offsets in between them. For me it is crucial to display subtle differences, which are smaller than the pixel pitch of my monitor.
I was thinking about implementing subpixelrendering to display this subtle differences.

The stimuli look like this:

What did you try to make it work?:
I cannot figure out how to implement subpixel rendering code into psychopy or if it’s automatically implemented already
