I have a customer that has two monitors and is trying to use our Unity web-player application in Dualview mode. Unity works horribly for them when using two monitors. If they disable Dualview - and just use a single monitor - there are no problems.
The customer has Windows XP and has NVIDIA GeForce 8400 GS graphics cards - plenty of video RAM …
Any idea what the problem could be? Attaching a screen shot of their display details. Would you suggest a driver update?
Well, dual monitoring isnt cheap to do when it comes to memory and cpu, (I would know because I also do dual monitoring). Its not worth it unless you have 2+ gb of ram and a nice cpu (considerably a quad or duo). As for dual screen on the webplayer, ive never tried it before, but it seems like somethings eatting up a lot of the power which is causing it to slow down. Also, as a side note, that video card is really outdated (as theres 400 series of nvidia cards now) that may be an issue, even a 9800gt overclocked should be fine, but the better the video card, obviously the better outcome, because as you know you hook up both monitors to the VGA output which is technically on the video card itself (Like some high end cards have 4 VGA outputs). I wouldnt recommend dual screening unless you have the appropriate hardware.
the geforce 8400 is not remotely on the level of a graphic card required for dual screen hw acceleration unless we talk about trivial graphics on the level of the time management games etc on bigfishgames that use barely any gpu
