Here is another update to RBRvr which should fix the latency issues with rendering introduced in v1.4. It took a long time to find a way to get it working properly, but now it should be a lot more pleasant to look at.
In addition it comes with options to disable the default camera shake in the in-car view and and to lock the camera to the horizon in either roll axis only or roll + pitch.
I did not have time to test it thoroughly so its possible there are some bugs as the RBR camera override is now done in a totally different manner.
See the readme.txt for instructions and some troubleshooting hints. In-game you can also find a quick help sheet from the desk.
