My results do not support it. The Shredder 7.04 UCI engine is much faster on my computer system (Windows 98se, 500MHz Celeron, 256MB) when run in the Classic Shredder 6 GUI. How much faster? I haven't quantified it exactly yet, but a lot! In typical opening/middlegame positions in infinite analysis mode (usually run for an hour or more), the Shredder 7.04 UCI engine usually runs at 100+ kN/s in the Classic Shredder 6 GUI, as compared to only about 70-80 kN/s in the Shredder 7 (CB) GUI. The Classic Shredder 6 GUI is also friendlier to my computer in general, using less resources, which is an important factor with Windows 98 and Me. WP
