Graphic compare AMD and Nvidia

[Fantasy]

Hello,
I test 2 games: Kingdom Hearts Birth By Sleep and Dissidia 012 Duodecim Final Fantasy
It seems that the graphic on Nvidia graphic card not good like on AMD graphic card with thoes 2 games.

Nvidia: GTX 470, driver version 314.07
AMD: Hd 7950, driver version 13.1
Both with 16xAF and high quality texture in driver, and same configuration in jpcsp.
I use jpcsp 64 bit version.

I try how to describle the differences: there are lines and the colors are odd with Nvidia. With AMD there are no lines to see and the colors are normal.

It is best to see it by the screenshort.
I don't know why, is it maybe I didn't have the latest Nvidia series (6xx)

How about your experience? Have any one good quality like AMD with Nvidia card ?

nvidia one seems to be in 16 bit, either through emulation or a glitch.

as far as i remember, this game has a 16/32 bit graphic settings to speed the rendering up/increase fps on a real psp, maybe ati version can't do the 16 bit color rendering right and defaults to 32 bit.

thank you
Is there any way to enable 32 bit on nvidia card?

i think the option's in game. try enabling it in the game's options and see if the graphics improved.
