Strange, but nHancer isn't a help here. And I don't understand the missing halo? Aren't we talking SH4 only?
Here's a demo:
Another demo, showing as good an image as I could get with the old ATI x1950 Pro.
nVidea do indeed require more AA to be as effective, but performance overhead is so great with this card, I rarely get below 100 fps...
My settings in nPanel:
AF - 8x
Gamma - Off
AA - 16xQ
Transparancy - MultiSampling
Texture clamp - off
Force mipmaps - none
Texture Filtering - High Quality
Triple buffering - off
Vertical sync - use apps' settings
I did experience nHancer screwing up nVidea's Control Panel
Had to use System Restore to get rid of it again...
