I track using Native plugins like virtual synths or guitars on Guitar Rig all the time, on an HDX rig. I usually put a DSP Trim plugin first in the chain, and use a buffer of 128 samples if the system will allow it. Latency is virtually non-existent.

I usually mix with a 512 buffer size, but if I'm doing overdubs later in a mix when there are a lot of plugins being used, and I can't reduce the buffer to 128 samples without the CPU load getting too high, then 256 is usually fine to do overdubs.

The usual culprit for latency is the mix buss plugins, so you'll need to deactivate those (bypass will not reduce latency) and make sure that the track you're recording onto is not sub-grouped, but goes straight out of the main mix output. Then you should be good to go!
