MAMEWorld Forums - EmuChat - MAME regular v slight glitching in Win 7 64 bit

Hi All,

This is driving me nutz!! Bit of background: I built my cocktail cab about 7 years ago and it has been happily running DOS based ADVMame and ADVMenu. Recently the PC inside is just playing up, Hard drive U/S etc. so i decided to use my old laptop to replace the PC with the bonus that I could then take my MAME system mobile.

The laptop is a Fujitsu Amilo T3400 2.16GHz / 2GB / 250GB with intel S4 GFX. It's running Win 7 64 bit.

Now here's the headache - there is a very slight but very definite glitch or stutter that occurs in any game at regular intervals - maybe every 2 seconds. So scrolling for exampl on 1943 of the clouds isn't smooth - just that tiny little stutter. Even more noticable on the last space invader when it's moving at fastest speed across the screen. It'll almost stop for the tinniest nanosecond.

It's not Triple buffer or vsync as I've tried those - although Triple buffer stopped the tearing that I did have.

It's almost as if the system is doing something every second/2 seconds that just ever so briefly impacts on MAME running. I am running at 800x600 resolution at the moment with Hyperspin FE and no hardware stretching of screen to fill the 16:9

I've started turning Win 7 features off but still haven't nailed it.

Unbelievable that my old DOS duron system could perform so much better that this modern set up!!

I have tried both MAME and MAME64 variants and it's the same with both.

Please - any suggestions welcomed!! I'm going nutz here!!

Even thinking of stripping back to XP (although that will be a right royal PITA for drivers)
