[comp.sys.ibm.pc.hardware] VGA chip sets

demoydk@iitmax.iit.edu (Enigne Yratorelknaw) (02/05/91)

Hello all you out there in the Net.  Is there any specs on the latest chip
sets for the VGA and SVGA graphics?  I heard here and there that IBM VGA is
the slowest, then Paradise, and some more...

Please let me know since I AM looking for a decent VGA system...

Thanks.

Our dept. recently picked up a 386-25 box with an SVGA card using the 
Paradise chip set.

  Question1: Is it normal for windows to take two to three seconds to
             repaint a screen? (actually about two thirds of the screen)
             This is in the 1024X768 mode.

  Question2: If it is NOT normal, is this a function of the driver or
             the hardware? Could a different driver for the Paradise set
             be used? 

  Question3: If the answer to both of the above is NO, what is considered
             to be the hot tip in chip sets.


Thanx in advance for yer help.

Yes. It is even normal if you have a hot super high speed graphics
coprocessor card instead of a VGA card. What's your disk doing
while the repaint is going on? I bet it's trashing like mad.
