Hello Please, can you explain? What dependence ScanlineSync and ReduceBlanking2 how its works?

DELL S2421HGF(Freesync disabled while using ScanlineSync via CRU)
rx580 Sapphire Pulse, driver WDM

Also i have hi vram clock amd bug at idle.

For reducing vram clocks i am try set CVT-RB2, clocks is low now at idle, BUT then i try using ScanlineSync at CVT-RB2 i have always constant stutters. If i manually set resolution vram and ScanlineSync works normally.

See attachment

just set it LCD Redcued and 144 its will make sure your gpu run in max clocks all the time

Scanline Sync works better with large blanking intervals (Quick Frame Transport = lower input lag).

Try NOT use reduced blankings with RTSS Scanline Sync if you can help it!

Bigger VBI = easier to hide tearing in VBI = easier to hide tearing between refresh cycles.

Reduced VBI = harder to hide tearing in VBI = harder to hide tearing between refresh cycles.

(Bigger VBI / large vertical total = lower lag too. since a higher scanrate at same refresh rate means the refresh cycle is transmitted faster over the video cable. Like a 144 Hz refresh cycle transmitted in 1/160sec over video cable. Sometimes it's favourable to reduce refresh rate slightly, e.g. 140 Hz, to enable a bigger VBI for RTSS Scanline Sync to perform much better).
