Haha.
DDR2 is what this thing can handle, I forgot what MHZ is the maximum.
Stuff is from 2007, 5 years old.
my PC is also 5 years old, 2gbs ram:
You need to 1/ FORMAT.
2/ uninstall mylittleponyonline and all the shit that starts up on windows startup.
CTRL ALT DELETE and violently kill 50 or so svchost process, pretty sure you will spot what ones instantly destoy your pc, dont kill those ones again: Your pc should be running at about 5% on XP, if it isnt, try to get a better SP. 2 is good, has much less Windows Security ROFL than sp3.
Honestly, this game is old, your pc is old: see the correlation: Worst case scenario set yourself to DX7, 0 ragdolls, 5 bodies.
Oh, and most importantly: Dont try to join EU1. 100 players with unique gear and face setup is killer, stick to smaller servers.
