My problem concerns settings in the BIOS which need to be changed to prevent jumpy motion on the screen when using things like the ultra smooth-motion screen saver Aquarium which uses DirectX 8.
Sometimes when running this fish screen saver the fish make little jumps in their motion but sometimes they scroll around smoothly. The same thing happens in MotoRace game where the whole screen will freeze motion for a split second, about a quarter of a second.
A friend who helped set up the OS on this windows 98 machine did tweak it to prevent this, but he's away at present. Now the interrupted motion has returned after some time. It began when I upgraded to latest drivers
for the screen (Matrox I think).
It's especially noticable after using the PC for a while and then testing the screen saver - I'm sure it's a simple value change needed but I am all at sea with the BIOS - any experts out there who can fathom this one?
