our measurements show its possible for an app using D3D DX7 interfaces with
DX7 drivers to see from 20-30% improvement over using D3D DX6 interfaces
with DX6 drivers.
this depends on codepaths; with vertexbuffers and indexed lists being (
generally speaking ) the fastest paths. this also depends on whether or not
the D3D T&L pipe is being used.
since I dont know what the Java3D team is doing with their implementation of
D3D, its hard to say what percentage of this improvement could accrue to J3D
DX.
note to the J3D team, if you have any optimization questions - off-line I
would attempt to be of assistance.
if its the DX runtime you need to cart around, note thats freely
downloadable from somewhere below http://www.microsoft.com/directx. you can
also get a CD of the runtime and SDK for a nominal fee.

Hello,
Before I go through the hoohaa of zipping up directX across disks to get it
home, does anyone know if there is much or any performance increase with
Java3D DirectX beta?
Thankyou,
Matthew.
