Title: Screen tearing using Vsync patch.
Post by: Xiad on May 31, 2011, 08:45:26 PM

So, the problem is occurring in PCB at the moment. I'm using the Vsync patch to counteract the control input lag issue, of course. Anyway, I've tried forcing wait for vertical refresh/triple buffering on the graphics card (ATI Radeon HD 4600 series), using Riva Tuner's D3DOverrider to force Vsync/triple buffering, I even thought that it was a ground loop issue at one point! Also, at one point in the past, I also noticed screen tearing with Winamp's Visualiser, but with triple buffering enabled, this problem seems to have disappeared. Strange how it shouldn't work with Touhou...
If anybody has managed to fix the same sort of problem before, I'd be very pleased to hear from you.

The vsync patch disables vsync, which is why you're getting screen tearing in the games.

I thought so... but can anything be done about it (short of sacrificing low control latency)?

I just live with the tearing, but if you look in vpatch.ini their is a line that says "Vsync = 0".  Change that 0 to a 1.

Dunno how much of a latency impact that will have, but it will be at least one frame of display latency.
