Description
According to this thread:
http://forums.java.net/jive/thread.jspa?threadID=41748&tstart=0
The new AA shader is much slower on NVidia NVS285 hardware
(which reports as supporting PS3.0).
From the thread:
The program below runs at about 800 fps with b14 and about 200 fps with b24 on my computer. Dell 380, 3Ghz Pentium D, Nvidia NVS 285, XP Pro SP3.
I tried disabling direct draw on b24 and it was about 10 percent faster than with it enabled.
OS Version = OS_WINXP Pro
