ti 4600 GF4 Gfx card (Sparkle)
Now tell me, how much MB does it has?
also when occuring graphical problems like LAG or something you might consider updating the Driver software of you Graphic card.
And also....I,m not really into DELL computers...my friend had one...but that thing had more ****load craptastic problems then an IIA boat having problems with an TASKFORCE with 30 meters depth underneath him while V&W and other Elite class Destroyers Depthcharging the hell out of that small sub.
But If i,m right thats an Nvidia right? Geforce 4...
how much ram does it got?
so:
-Update your Vidcard Driver
-Download latest patch of SHIII 1.4b
Good luck
