1. Tearing can be avoided by using VRR but besides the upcoming Gsync Pulsar you cannot use VRR and BFI simultaneously. If you use BFI, tearing is still a thing. Stutter happens with low framerate or framerate fluctuations which is also independent on BFI. CRT motion on such an LCD is possible despite high GtG response times if the GtG transitions happen during the darkened screen. If the strobing is timed perfectly, motion can be awesome. See the Viewsonic XG2431 discussion.
2. Some PS5 games have internal VSync options. There is no system level option, but I cannot tell if there is an internal system level cap implemented by Sony.
3. If there is no setting on the PS3 for that, it might be impossible to force 30 Hz output.
4. There are videos on YouTube which show that it's rolling scan. Newer LG OLED like the G5 have classic BFI (black full frames between two input frames). Do not confuse the last technique with global strobing from LCD, because OLED have no global backlight.

Do you think flicker free rolling scan of pvm 2541 sony pro oled can reduce 24p stutter?
I watch movie isles of dog and there is a normal speed panning shot has a very noticable stuttering,it will be smooth like 60fps motion if frame interpolate kicks in.
But i hate this way and i am wondering if flicker free of sony pvm can work like frame interpolate.
Also this is a 60hz panel but has two panel frame rate 48hz

may i ask
can i extend oled gtg time ms from 3ms to 10ms to reduce 24p stuttering?
i have a slower gtgms x900e which has better 24p stuttering motion than lg c1
can i suggest a good movie scene to test 24p stuttering but not 3:2 pull down 24p judder?
2.chief said 120hz dlp projector has 8.X ms presistance blur as other sample hold display
but dlp is a non sample hold display ,does it have better motion blur than 120hz non strobe oled ?
3.why lcd vr headset quest 2 and eizo turbo 240 monitor have 0.3ms and 2ms presistance blur?
A 120hz display has 8.xms presistance blur but why quest 2 has 0.3m ,even you strobe 120hz signal you will get 4ms presistance blur

Frame interpolation is the only way to reduce stutter and increase motion clarity without flicker.

1. You cannot extend the OLED GtG times. Because of OLEDs fast pixel response times stutter appears heavier than LCD with slow GtG.
2. DLP projectors are technically strobed, but at very high rates (kHz). As far as I understood, that strobing is only used to adjust the brightness by doing Pulse Width Modulation. It is not the same principle as showing Frame A for 2 ms and then being dark for 6 ms, which would indeed reduce motion blur.
3. VR headsets use backlight strobing (LCD) or rolling scan (OLED) to reduce motion blur because when using a VR headset, it is necessary to have low persistence to avoid motion sickness. This is also why they run at refresh rates higher than 60 (90 or 120), to avoid the perceiption of flicker for lots of people. Of course that is possible on consumer televisions too (like the CX or C1 proved to us), but as lots of people are unaware of the existence of motion blur, manufacturers do not care about implementing rolling scan in modern OLED anymore.
