It’s not about anticheat per se but about kernel-level anticheats, which are just overkill in a PvE game. I’m not sure about the other games you mentioned, but at least Apex has no kernel-level anticheat.
This has been an issue since NVIDIA introduced alternating frames in the 545 driver. To fix this, explicit sync was recently merged into the Wayland protocol, now all it needs is the merge into Xwayland and the new NVIDIA driver that supports it, which is rumored to be released as a beta around May 15.
Until then, you either have to game on Xorg or use the 535 driver.
AFAIK polybar is X11 only, so OP is probably not looking for a Wayland solution, right?
