[rdesktop-users] lagging problem

[Yogesh P. <glo...@gm...>]

Hi,
       My both computers are connected to same 10/100 Mbps 8 Port switch, 
and also tryied with different switch and different LAN card, but problem is 
that when i try with Celeron-333 with 2MB, Celeron 600 With 4 MB onboard SIS 
VGA, still screen lags with 16 bit but when i try with AMD 2200+ with 4 MB 
onboard 16bit/24bit display it works fine with no problem what is the 
reason..????
         will upgrading to 4 MB PCI vga solve my problem
          I am getting same problem with LTSP, Thinstation, Indivisual 
Rdesktop, pxes.
Regards,
Somani K.
