Hi.
Why Mame (either Groovy or not) is running at about 60-90% most games with a 8 core 3.7 ghz Xeon CPU, a Nvidia Quadro k4200 and LCD screen (yes, I know that's for working...) ? It's like it's trying to run them at 85% instead of 100% (even Mario, Ghosts N Goblins, Moon Patrol...).
My 9 years old laptop connected to a CRT TV runs most games at 100%.
I messed with all the settings I could imagine in both Groovymame and plain Mame (opengl, double buffer, vsync, etc.) but it keeps running slow no matter what.
Any advice?
PS I'm at the office, I can paste Mame.ini later at home.
