Still no fix for the BFI input lag on this monitor?

Can confirm, Still issues with BFI lag
Even on MCM104 firmware. So disappointing, trying to contact ASUS and see if this will be addressed.

I just measured the ASUS PG27UCDM (4K, 240Hz, QD-OLED, firmware MCM105). ELMB is only available for 120Hz input refresh rate, and input lag is 10ms or 14ms (at the screen center). Whether it is 10ms or 14ms depends on the moon phase when activating ELMB, meaning it probably depends on exactly when during a refresh cycle ELMB happens to be activated. But, at last, it is stable within an ELMB session.
