I ran the stock “Camp Pendleton” database (VSB) in Lynx Prime 4.0 and it ran over 150% faster than the same db (presumably) running in Lynx Prime 3.0. On my NVidia GeForce 9800 GT card w/ 512 MB it ran at 480 Hz (vpWindow Swap interval = 0) and 186 Hz on LP 3.0.
There are some issues with upgrading my user module that I need to look into.
