well first thing we need is install sys-clk and the sys-clk overlay (the first one is the main one you need the 2nd one is merly a tool to make it easier to configure)

to open up the tesla menu with "Left shoulder + dpad down + right stick press"
from there select sys-clk overlay and first turn it on. then set the values for handheld or or docked depending on how you plan to use the console to this:
these numbers made most of the frame issues at-least on my end disappear.
