I just installed a EVEA Nvidia 7800 GS OC. I also installed the new drivers found at the the Nividia driver site. These are my results:
I set up the card using the global settings and created this file to work off the sh4.exe. I set AA/AF to X4. No jaggy. Very smooth.
I see two of my screenshots on this thread. These shots were taken using a ATI X1300. At one time I was able to get sun halo as shown in the second pic. Normally the ATI looked like the first pic....just a round circle.
Driver version 6.14.11.6921. I guess the latest drivers for the 7800 card found on the Nvidia site.
