MAME input lag?

[John Simon]

Can GameEx be the source of any input lag on MAME?  I wouldn't think so, but I am seeing unbearable lag in games launched from GameEx but not if I run the game directly from the MAME GUI.

Please attach your gameex.ini and log.txt files if you don't mind attaching from after when the lag occurs.

Also, what version of MAME are you using?

Its possible, yes, but unlikely. Would need to see logs etc.

Thx, will do.

Here are the files.  I am using MAME0262b.   Thanks for your help!

I looked at the log and saw that there were some plugins enabled.  I disabled them and the problem went away.  I am not sure which one it is, but will play around with it and see.

Just saw this for the Infoz plugin:

The Infoz plugin may only be the one to disable in your testing.

There were also improvements to potential lag in a newer version than  you are on. Is there any particular reason you are using an  old  version?
