OK people it's finished I hope that this will help all those who are having lags whit roman units (and some hoplites)
What this patch does?
Well it overwrites the original mesh files which the Romuli faction uses ie it replaces the very high poly models (which were cousing lags) whit the normal poly ones so the people whit lover end machines could enoj the mod whit out any lags.
If you have the desire to play whit the high poly ones again then you should reinstall the mod.

INSTALL INSTRUCTIONS:
After you have download the file move it to THERA folder (which is in your MTW2 mod folder) then extract the file there, it will ask you if you want to overwrite some files you have to confirm that for all files (YES TO ALL button is the best solution).
Any bugs for this patch should be reported in here so I don't have to chase the bugs through the other threads.
Off course tell me what you think about the quality of the units after you have tried this.
PS
HAVE FUN & ENOJ!!!!
