What's your settings?
EDIT: This sucks. Everything runs very smooth, the 3D backgrounds on the menus on Capcom vs SNK 2, the sounds, the character select, but once I get to the stage, it just bogs down. I can play it but its just slow, the characters are moving in slow motion, but the sound is correct, its like the animation is bogging down but if I delay my control presses I can play the games, barely. I can't figure it out, I have 3Danalyzer running force SW TnL and that's all. It isn't helping. Naomi.ini is still at default. The only game that works decent is Street Fighter Zero Upper
