NVIDIA G-Sync Pulsar monitor - Asus ROG Strix XG27AQNGV

Ask about motion blur reduction in gaming monitors. Includes ULMB (Ultra Low Motion Blur), NVIDIA LightBoost, ASUS ELMB, BenQ/Zowie DyAc, ToastyX, black frame insertion (BFI), and now framerate-based motion blur reduction (framegen / LSS / etc).

Does someone know a trick to have the lowest latency but still no tearing with 120Hz ULMB2?

I tried various forms of scanline sync, but in all cases I can’t seem to get it to work flawlessly, at one point the tear line is back. Also moving the line up/down does not really work as expected, neither with SpecialK nor RTSS. When I move the line 1 up/down, the tool syncs again and the line is at a random spot again.

I saw that fast sync with a (actual Hz - 0.01) limit seemingly has the lowest latency and still no tearing? Interestingly enough, it seems to work in some games, but not with all. Is that normal?

Besides that, low-lag V-Sync does work pretty reliable, but it stutters a bit, which is of course way more obvious with great motion clarity.
I'm wondering as well and its part of the reason why I still use Pulsar at that refresh rate range. I find the latency is too distracting with 120Hz ULMB2 + V-Sync.

I have asked the same thing some days ago but did not find the time to try kyubes suggested methods. So you did try this? Not successful?

Just saw your post. Tried Scanline Sync and Fast Sync. Like kyubes mentioned though they require 2x over framerate cap to work well. Scanline just straight up doesn't work in some games and it struggles when gpu utilization gets too high.. Fast Sync is a stutter fest unless you have the framerate headroom. Under ideal scenarios they both work pretty well though. They're just not good enough to just turn on and forget.
