CRJS so you are saying the latency between motion blur reduction on and off can be felt through gameplay? If so, it must be quite big for it to be felt. Since you got the alienware you must have the reflex analyser, could you test if the case is true and not a placebo?

Where do you access these pursuit shots? I looked up that video "1624898023991" on YouTube and couldn't find anything.

AW2521H absolutely has more latency with BFI enabled. According to RTINGs it is 3.8 ms for that specific model. Unlike all of those YouTubers and reviewers who make blanket claims without evidence, I am not going to say that it is not noticeable. I personally think it potentially could be. It also makes it so that no matter what you will always see what's going on 3.8 ms later. Maybe the BFI clarity makes the human element of reaction fast enough to compensate, however. What is very interesting is that the ASUS VG279QM has equal input latency with BFI on and off.

Hmm? I confirm that in my unit I cannot change the overdrive. Please, can someone with Nvidia GPU try to change overdrive with "Fressync On"?
I have an NVIDIA GPU and with my unit it is possible to change Over Drive (Off / Normal / Extreme) while AMD FreeSync Premium is On.

Ok, thanks. Then is locked in "Normal" for AMD GPU users ( at least for me, RX 6800XT ) and unlocked with NVidia. Gsync-OD works correctly despite is not officially certified by NVIDIA as G-SYNC Compatible? Please, can you talk about perfomance with Gsync ON OD Normal vs Extreme?

I don't know how to use G-Sync, it does not appear in NVCP.

Whats going on here? Different batches?
Can you please name the monitor you have, Acer Nitro or Aopen FireLegend? And can you check the firmware version?
Note that VRB/TVR needs to be disabled.
