Rockets look like flying debris

Hello
After a long time, I reinstalled Zero-K and noticed something weird.

How can I resolve this?
Thanks!

I reinstalled my AMD driver Software and fixed this problem
I had same problem after change AMD driver Software (to new unstable version? I not sure...) before.
I reinstalled Zero-K also can not fix it.

On the related subject of AMD vs nVidia... any ZK graphics guru want to comment on the current state of things? Does the game have a lot of code specific to one or the other? Is there a noticeable difference in correctness or completeness of the opengl drivers these days?

AMD vs Nvidia isn't a matter of there being code specific to one. ZK (well, the Spring engine under it) just runs on openGL, which is better supported by Nvidia drivers. So some things that should work just don't with ATI drivers.

Apparently AMD did an overhaul of their Windows OpenGL drivers this summer.

The next interesting event will be the new Intel GPUs, probably not an efficient driver, but I wonder about the correctness/completeness. There is a fair bit happening with new CPUs too, huge caches and higher clockspeeds, exactly what the ZK engine ought to like.
