All of which goes to underscore my astonishment that an essentially cross-platform client and server together weigh in sizewise at about a quarter of what typical "competitive" products do... ----- Original Message ----- From: "James ''Wez'' Weatherall" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Cc: "VNC-LIST" <[EMAIL PROTECTED]> Sent: Monday/2002 March 04 10.24 Subject: Re: winvncdrv new version available
: The existing official version of WinVNC can only obtain hints as to changes : to the display, which it must then verify since they sometimes overestimate : what has changed. Conversely, some updates (some scrolling, some console : windows) cannot be hooked for hints, so WinVNC polls them, chewing the CPU. : : Using a display driver allows WinVNC to obtain accurate data on what has : changed, vastly improving performance (try moving the mouse pointer with the : two different versions and the difference can be very noticable - and that's : a relatively small graphical update!). : : Essentially, the display driver is the way WinVNC should have operated from : the beginning, but since it works only on NT and could cause system : instability, we opted for the hint route instead, which is more portable (to : Win98, for example) and cannot crash the OS. (Note that Rudi's version uses : a hook driver that I've never seen crash a system, so the instability point : is probably moot). : : Cheers, : : --- : James "Wez" Weatherall : "The path to enlightenment is /usr/bin/enlightenment" : Laboratory for Communications Engineering, Cambridge - Tel : 766513 : AT&T Labs Cambridge, UK - Tel : 343000 : ------------------------------ : : Date: Sun, 3 Mar 2002 10:50:41 -0500 : From: "John Roland Elliott" <[EMAIL PROTECTED]> : Subject: Re: winvncdrv new version available : : Considering the originator (R.
