I'm curious if anyone has done or is capable of doing an input lag test on the current version of Mame (0.146) on a Windows 7 system. Preferably using a VGA CRT for an accurate measurement. I've also noticed that Win7 USB poll rates are 125hz aka 8ms by default; granted there are a few hacks to force the 1000hz (1ms) rate, in addition to utilizing usb mice that support that poll rate. I've tried doing a rough side by side comparison of running Super Turbo via a supergun through CRT in comparison to running the emulated version on a dedicated laptop and it appeared really close in terms of input delay. Would love to get an exact measurement though.
Any information regarding a test such as this would be greatly appreciated.
