Black Sheep Posted June 6, 2011 Posted June 6, 2011 Hi girls, when flying FC2 I see something strange in my monitor. I suppose you all know what is "tearing". As trackir (4) user, I hate tearing, that's why I set VSYNC ON (with triple buffering), and it works. I knew you have tearing when you graphic card sends spits out more frames than the monitor can handle. The problem is that sometimes I see tearing even when I shouldn't: my LCD works @ 60hz and I see tearing even when FPS counter (ati tray tools) tells me I'm playing @ less than 60 (eg: 50, 40...) What's the problem?

Black Sheep Posted June 6, 2011 Author Posted June 6, 2011 I'd say 60hz,that is what I set in video properties. Why do you say 59.4Hz?
Wolf Rider Posted June 6, 2011 Posted June 6, 2011 check on the monitor itself, not from the PC City Hall is easier to fight, than a boys' club - an observation :P "Resort is had to ridicule only when reason is against us." - Jefferson "Give a group of potheads a bunch of weed and nothing to smoke out of, and they'll quickly turn into engineers... its simply amazing."

Black Sheep Posted June 6, 2011 Author Posted June 6, 2011 check on the monitor itself, not from the PC You could be right! I checked on the datasheet (I'm not at home now): it says the real vertical frequency for 60hz 1920x1080 is 59.934 or 96.963 (it shows 2 different full HD modes) So, what's the point?
Wolf Rider Posted June 6, 2011 Posted June 6, 2011 from what I understand, they are a TV screen and not a true computer monitor... terrible for sync'ing - at least the 59.4 screen, not too sure about the 59.9(?) flavour though. Windows expects to see/ work with a true 60Hz City Hall is easier to fight, than a boys' club - an observation :P "Resort is had to ridicule only when reason is against us." - Jefferson "Give a group of potheads a bunch of weed and nothing to smoke out of, and they'll quickly turn into engineers... its simply amazing."

Black Sheep Posted June 6, 2011 Author Posted June 6, 2011 I suppose and hope it's a computer monitor: it's a HANNSPREE HF237HP, very cheap, not so good but good enough for playing. Anyway, vsync WORKS and do the job: FPS doesn't go over 60 and tearing is no more. Anyway sometimes (not always) I experience minor micro-tearing episodes also at low fps. When I experience the real tearing (vsync off) my screen is cut in three or more large bands. In micro tearing I see narrower bands less annoying then the real tearing, but annoying... I'm wondering if it's really a tering issue.
Black Sheep Posted June 7, 2011 Author Posted June 7, 2011 Solved Solved. Sometimes I used to forget to enable vsync before starting FC2. Closing FC2, enabling vsync, restartin FC2 is BAD. It seems vsync cannot be enabled/disabled "on the fly". It's like Vsync is "not really" or "badly" enabled. This leads to strange video behaviours like - in my case - tearing even at low fps. Starting the PC, enabling vsysnc (if not already enabled), and running FC2 is OK: FPS doesn't go over 60 and NO TEARING AT ALL.
