I never considered to install the un-offical update lol seemed to be dodgy. One thing that my retro does pack really well is the Pentium 4. I mean it ran most of my old school games well such as All Command & Conquer games (Up until C&C 3), AVP1 & 2, Conflict Desert Storm 1 & 2, ShellShock Nam 67, MechCommander 1 & 2, Emperor Battle for Dune, Descent 1 & 2 (even with the upgraded graphics rebirth mod), Classic Doom 1 & 2 (Brutal Doom mod), and many more i could mention on here... there's something about playing classic games on old hardware it's like going back in time..
it's an early 2000s Dell machine maybe there's drivers that i missed and those are still on Dells website. Might need to check it out.
