using a Radeon vidcard, there's good news. The new Catalyst 3.5 drivers
appear to have addressed the problems.
Whereas until now you had to set the D3D Texture Slider all the way to
"Performance" in order to not have trackside objects with gaping holes,
you can now have the slider all the way to "High Quality". No more
adjusting your settings back and forth between GPL and more modern sims.
For reference, my system is a Radeon 9700Pro under WinXP Pro.
