It seems to be incompatible with DSR, on all tests I did on games and demos, any DSR resolution gets the rendering tear line in one fixed location at the first 80% of the screen and no way to move it outside that area, the bottom of the screen is not reachable,
can someone confirm or share some trick to make it work with DSR?

Not only DSR. But also custom downsampled resolutions suffer from this issue.
And on DSR, the FPS gets capped to half of refresh rate with scanline sync and only way to fix it is by alt-tabbing or switching to window and coming back to fullscreen on some games.
But many games crash when alt-tabbing or just doesn't alt-tab at all.
Scanline sync really seemed like a good idea but it's broken af now. Hopefully updates can fix it.

Just in case someone is interested I did a measurement of input-lag with Riva tuner and Scanline sync and compared it with Vsync Off, frame limited ingame on Battlefield V.
It is done Battlenonsens style, however it is not the most accurate measurement as I only had possibility to record at 240FPS. This info might tell you what additional input-lag you could expect.
Below the results:
Rivatuner Scanline Sync ON 60fps:
92.4 ms
71.4 ms
71.4 ms
58.8 ms
Riva Tuner Off, Vsync Off Framerate limited ingame to 60
54.6 ms
37.8 ms
29.4 ms
37.8 ms
Not enough passes to make an accurate average but.... if you eliminate the max and min you end up with 71.4 and 37.8 so a 33.6 ms difference. I can feel this difference when playing but to be honest it is lower than I was expecting.

I woke up very early in the morning and had some spare time so I changed a bit the measurement system. Opted for the LED signal and not recorded movement which is sometimes more difficult to approximate. The Button to pixel delay is a bit different but the difference with/without RTTS and Scanliine sync seems to be similar.
I don't know if the difference between old method and new is due to the different mouse or due to movement approximation.

Conclusion: Scanline Sync ads another 30ms inputlag which is not that bad considering Vsync ads double (63ms).
PS : All this was measured on my OLED 65E6 LG TV at 60fps. Another point is that HDR and SDR game mode have the same inputlag.

I just heard about this from Reddit today (well, I noticed it in the [url=https://rivatuner.com/]RTSS [/url]change log but I didn't know what it meant) and I'm surprised there wasn't much discussion here as it's been out for a bit.
At first it sounded like a poor man's G-Sync/FreeSync, but now I'm not sure. It seems like it's more like Nvidia Fast-Sync or AMD Enhanced-Sync but with a better method.
This will probably be great for e-sports games, where you want to lowest lag but want to remove the tearing.
But you still want to be maintaining at least your refresh rate in fps (or ideally much more), so it won't be as useful on newer or demanding games.
Maybe I will give it a shot though just to see how it looks. Always nice to have another trick in the bag.
