Invisible Objects and lag

[815]

<p>Hi, I have been having some problems recently with lag and invisible objects in game, My system information is 1gb ram, 128 mb ATI Radeon  Xpress 200M series, I also posted a topic about crashing recently, if i left anything out look there.</p><p>I have my game set to run at minimum settings and it still lags there, I believe i have more than the minimun settins to run game, before i could have the settings reasonably high and run game fine, but now i have to leave settings at absolute minimum and it still lags, I have current sound/graphics drivers (as current as can be, which is about 4 years old, dicontinued series) and it didn't seem to help at all.</p>

<p>I am running Windows XP 32bit Home Edition, Thee are not any programs running in backround and i increased my sytem file space from 756 mb to around 2000 mb and it didnt seem to help, is there a way to check if all of my memory is enabled and able to be used by game? from the crash messages  the max is 640 mb for the game.  I ave defragged my computer and there are minimal fragments, also cleared temp and prefech files. Is there anything else I can do?</p>
