Anyone else tried running NullDC1.0.4 with GTX680 / windows 7 64 bit?
I have an Apple 30" cinema hd display connected with dvi.

They have this weird full screen mode in NullDC which isn´t quite true full screen... and the vsync just doesn´t go on!

I get horrible tearing even in 2d games like Gunlord, well it´s handled by direct3d still. It´s present in actual 3d games too, maybe to a slightly lesser extent. Very disturbing everywhere every time it happens. I´d quite like to completely get rid of it.

I have tried:

Setting vsync on from application
Setting audio sync on
Forcing vsync on from control panel
Changing windows 7 themes between aero and non aero
Rivatuner and direct3doverride
Latest whql and beta 304.79 drivers
The tearing just won´t go away
I tried different emulator called demul as well as older version of nulldc which is supposed to have different kind of fullscreen mode... but that doesn´t seem to work with Gunlord at all, which is my main reason for trying Dreamcast emulation anyways.


I have one more thing I can and will try... and that is integrated Intel graphics... but that is ridiculous and there is only hdmi out so I would need adapter for hdmi to dvi Any other ideas? Oh right... a real Dreamcast. I´m getting it but it takes a while to arrive!

btw, enabling triple buffering reduces but does not remove the tearing. Yeah. The worst possible combination of triple buffering + vsync makes fps drop from 60 fps to 49-52ish and still there is tearing. It´s so bad it is kind of funny.

edit: I think I solved it. I just need to *disable* vsync everywhere and enable "limit speed and sync audio" in nulldc. That seems to have done the trick. The tearing is gone! Phew.
edit2: nope, it was back shortly afterwards. Next post explains what actually was going on.
