Tech knowledge: Low, red
I suppose this shouldn't come as any surprise at all, but dear God, the Sims 2 community offers some of the most idiotic technical support information known to humanity. Consider this:
"I see alot of people having issues w gameplay etc. I had the same issues such as VERY slow, choppy, and just poor performance in general. As of last night the game runs perfectly and Id like to share the steps I took to achieve this and hope it helps a few people... The 1st thing I did was went out and bought a ATI AGP Radeon 9200 Video Card... Next I bought a AMD Athlon XP 1800+ CPU. That made a VERY Nice improvement, however I found out my motherboard was clocked at 100Mhz NOT 133Mhz. I set the jumper to 133Mhz and WOW!!! Now my PC133 RAM is clocked properley, and with this new Athlon Chip this game is AWESOME!!"
So you bought a new video card and a new processor, and it magically improved performance! Please stop affecting any level of tech-support knowledge now, please.
