KDE 6.6.4 Allow Tearing option does nothing on Intel Arc B580

Even with window rules that block compositing, and allows tearing, even when applied to ALL windows, my frames still have zero tearing and games feel somewhat laggy.

I have tried setting all of these too:

KWIN_DRM_NO_AMS=1
KWIN_DRM_DISABLE_TRIPLE_BUFFERING=1
KWIN_USE_HWCURSOR=0
KWIN_DRM_USE_EGL_STREAMS=0
MESA_VK_WSI_PRESENT_MODE=immediate
vblank_mode=0

Does it just not work on intel graphics? I am lost as to what else I can try.
