| Severe button lag in some emulators... |

Greetings. This weekend I upgraded my MAME cab computer from Win98 to XP. MAME and MESS worked just fine after the upgrade. However, a couple emulators (NES: FCEUltra and SNES: ZSNES) exhibit severe input lag (like a second or two after I press a button, the emulator reacts). Any ideas how to fix this? |

We need more information otherwise people tend to make gross assumptions. |

Sure, I'll give it a try. For example, if I fire up Super Mario Bros on FCEUltra, when I press 'right' on the joystick, it takes a second or two for Mario to move right. Same with every other direction, jumping, etc. The same keypresses provide instantaneous freedback in windows and even MAME, however. I'm using an IPAC4 in USB mode if that matters. This all started happening right after I upgraded windows. :banghead: I would have assumed it was just FCEUltra, but I get the same exact behavior in ZSNES. Let me know any other information which would be helpful. |

Decent PC? (Just making sure you aren't trying to run XP with 16MB of RAM) Because this your cab PC, I'm assuming you aren't running any other apps in the background. True? Did you upgrade to Xp or clean install? Have you tried a keyboard or the IPAC in PS/2 mode? Are you using a USB hub? 1.1 hub or 2.0? Is there anything else attached to the USB bus? |

My PC is only decent, but should be enough for XP: Athlon XP 2000+ with 512 Meg RAM. I performed an upgrade instead of a clean install because I was lazy and didn't want to reinstall things like Winzip, etc. Maybe that was a mistake (although everything else seems to work peachy). I turned off a few unnecessary services, but I really need to thoroughly go through and strip it down. Good call on the keyboard in PS2 mode, I'll try that when I get home. I am using a USB hub but I'm not sure if it's 1.1 or 2.0 (can't remember). In addition to the IPAC, I also have an Optipac attached to the same hub (which seems to work fine). I'll check some of these suggestions when I get home. Thanks for the help. |
