I done my first experiment with Vergil without changing HD texture settings, the result for creating tpf files kinda depends on your project size you must wait longer) and I managed to decrease the loading time.
I doubled my project for testing to see results for Dante & Vergil with better quality, I didn't see any specific changes for Dante that much but that doesn't mean I did wrong just can't find spot changes then Vergil for any improvement.
I will keep you guys up to date for any key improvement.
