Input Lag Is Gone When I Use IGPU

[imprecise]

There are 2 things that could explain it here.

Sometimes HDMI has less input lag vs DisplayPort.

Your iGPU may not support multiplane overlay (MPO).

To further that post ^, here's where you can compare multiplane overlay (MPO) config/status.

• (Windows Key) + R, then run "dxdiag", choose save all information button, save it wherever is convenient.
• Open the file and look for keyword MPO (CTRL+F to find)

MPO MaxPlanes: XXXXX
MPO Caps: XXXXX
MPO Stretch: XXXXX
MPO Media Hints: XXXXX
MPO Formats: XXXXX

This is what I've got. Is this good or bad?

This just says you have multiplane overlay enabled.

I guess, it's disabled. I'm right?

Yes, yours appears to be disabled. What GPU?

I just tested this and before/after MPO planes was 4. This registry fix doesn't appear to work on pre-461 drivers.

Here are my results, RTX 3060ti, modded Nvidia Xtreme-G driver 528.02

Btw, I tested both with DP and HDMI. Whenever I use intel GPU, my monitor feels accurate. Like it refreshes more often and I don't get the feeling that I'm delayed in the game. Fps is usually around 90 and below. Also I tried capping fps 90 with rtx and does not feel the same.
