There's no primary monitor setting in duplicate mode. Not on Windows 8 at least.
You don't have a Crossfire setup by any chance?
no crossfire...a single gtx480...
Having Vsync off makes it better in demos like tuscany where you get 200+ frames...there is so much tearing going on then and the torn images aren't
temporally separated that much that is seems there isn't any...still the world doesn't have a solid feel...you can tell from straight lines etc.
In heavy games or demos where you're only slightly over 60 frames or worse...under..things look so unreal without vsync
I just don't get why there could be a sync problem if both DVI clocks are the same (are there 2 BUFFERS maybe...thinking about it there probably are)...The tearing isn't there on the main monitor yet i have my rift now in the first DVI slot of the gfx card which should atleast maybe electronically put it in some sort of master position over the DVI clock.
I don't know...there is clearly something wrong nvidia is doing when duplicating.
Is this why people are talking about DVI splitters etc...Does everybody suffer from it but are most people just naturally capable of not caring about tearing
like imo most people don't care about it on an LCD and do they just turn vsync off?
