Dowding, yes it's normal..personally, I dont like anything bigger than 1024, as it gets very hard to read the chat above that. (And then it becomes even more distracting!).
Blur, it depends very much on the car, track, the setup and driving style.
Personally, I wouldnt recommend drifting before you have learned to drive...this means tail braking, slow-in-fast-out, etc.
A good example is Spa. We just did a couple of races there, and while some take Masta flatout, I had just as fast an exit speed, even though I lifted a bit before entering it, simply because I didnt scrub the speed off by drifting.
