Sounds like a video problem to me.
With out more information I can truely say though. But I can say what I've
done to get planetside running on vista on my machine.
1) Run Planetside in Nt 4.0 mode (don't know why, but this seems to be the
best one)
2) Run Launcher in WinXP mode
3) Turn off (do not disable) Superfetch service
For some reason the Superfetch service was competely screwing with
Planetside for me. If I have Superfetch running, I can get into the game
maybe once every 20 attempts. With Superfetch turned off, I get in every
time.
So far Video, Sound, Mouse and gamepad is working just fine.
