Easiest (by a wide margin) -- Plain good old VSYNC ON + NULL
Still reasonably easy -- Low Lag VSYNC HOWTO
Hardest but lowest latency (and possibly less smooth) -- RTSS Scanline Sync
If you keep using RTSS Scanline Sync -- you might want to attempt a larger VBI (a Vertical Total bigger than 1125) to have more room to hide a tearline offscreen between refresh cycles. Or if you use VSYNC ON / Fast Sync -- intentionally calibrate it with VSYNC OFF to put the tearline visible 2/3 or 3/4 down the screen (healthy margin above bottom edge), then intentionally turn on VSYNC or Fast Sync while keeping RTSS Scanline Sync enabled. The nonstandard combination of sync technologies perform best that way.
i've currently gone for the scanline 2/3, 3/4 and vsync on (if the tearline bars when testing wobble too much - lower in game settings to stabilise? or does it not matter as much as long as the tearline doesnt drop out of view and come round to the top)
