Assuming I'm using OpenGL Driver 1.78 for video, DirectSound Driver 1.0 for sound, and whatever else:
What's a good config for the emulator so everything displays properly in FFT?
PGXP has absolutely no effect on FFT, unfortunately. Even Menafen's PGXP doesn't do anything. Thankfully, the jitter is only noticeable during slow camera rotations, so not much loss, there.
As for any other settings... Set the internal resolution multiplier in the config file as high as you can handle, preferably at least up to your monitor's native resolution, if not higher. I hate texture filters where they weren't intended to be used, so set xBRZ however you like.
Well, the way I had it set up the world map wouldn't display properly for whatever reason. Also, the internal res multiplier is for OGL2 which isn't what I'm using because the Dell is older than sin.
