ATI Radeon 4870, Original Drivers, Mouse Jumping/Stuttering/Lagging

[Shauneh]

I thought it would be a good idea to buy the:

 

GA-GV-R487D5-1GD

 

This is a non-reference design by Gigabyte and it seem that it doesn't work well with the Original drivers from Apple.

 

From what I can tell the original drivers and this card card causes a stutter, lagging or jumping on my G5 USB Mouse.

I tried a different mouse as well with the same pattern.

 

I worked this out buy rotating the mouse very fast and timing it in my head it seems to be at the same set interval,

at first I thought it was only the mouse until writing this post where I then held down the 'h' key,

after a few seconds I noticed it was stuttering the keyboard as well, it wasn't a RANDOM timing, It happened in the same place every few seconds.

 

I have the 1GB Model of an ATI Radeon 4870 made by Gigabyte, and I have read a few posts hidden very deeply inside of them, that this effects some Sapphire models as well

 

I hope someone will find this information helpful, don't forget to post here with your own thoughts and information.

 

Thanks,

They say:

it helps using DVI-VGA adaptor. I'll check later if it works on my system.

 

 

EDIT:

It works No more mouse jumping, stuttering and lagging.

 

I hope there is another way as I'd like to have digital output on my LCD.
