Try the Sunset Riders intro, the part where all 4 heroes are shown in a panning shot. In a CRT it's a perfecly smooth scene, it should also be in a monitor with Gsync/Freesync, anything else you'll see stuttering/tearing.Can anyone with some better understanding of CS explain what kind of magic this is?
I have a dual monitor setup, vert 144 Hz Gsync and hori 60 Hz non-Gsync. I have Retroarch setup to support VRR and when I play, say, Raiden Fighters Jet on primary display, it changes the refresh rate on my Gsync screen to 53 Hz, gameplay is smooth, etc.
Just for a lark, I tried playing it on the non-Gsync one, and it also outputs at 53 Hz (according to Retroarch OSD info), I don't see any tearing and the background scrolling is smooth.
Any idea why is this even working? By all accounts it shouldn't work. Is this Windows Compositor doing some black magic? Is this just something that seems to work, but comes at expense of severe input lag or something else? Are my old man eyes not seeing the tearing when it's vertical? Or is my computer just cursed?
I just remembered there was a MAME variant where, for high speed VRR/gsync/freesync monitors (120+), it would add a blank screen between each shown frame so it would emulate the flicker effect of a CRT, the result was perfect smooth scrolling.
