Hi
While looking at the R300 driver. I am trying to understand the driver.
I have found something i find interesting.
I am playing NWN and have fore some time had a little problem when i use
the scroll wheal to zoom in and out. Everything get rather slow when i
zoomed close on my character.
I have been playing around with the dri drivers for the R300 (I have a
ati radeon X700 PCIE carde). The attached patch makes my problem in NWN
go away.
I don't know yet why it works like that but with a bit of luck i might
find out some day.
