I do not get a delay. I do get the missing 2D elements (GUI) on a clean .urbanterror dir though.
I have lib32-virtualgl installed so as far as I know that should be enough to let 32bit programs to run.No, you still need 32bit drivers. Installing lib32-nvidia-utils-bumblebee should do the trick. However, using the suggested native method above would be a lot cleaner.
