The warping is something that is native to Crysis. Hopefully, it won't be as bad with the installation of our next server side mod. I'm not sure when this will be applied to our main server, as I suspect that there will be much testing and setting up required on the practice server first.
In terms of tips, I'm not sure where I can start, but I can link you to Ripley's PS guide
