Turning off bot chat won't help... Can you write your computer specs here? I work on my old PC very often, and plays on it too (P3-866 / 256 MB / GF 4 MX440), so i haven't noticed any slowmotion, while bots number is < 17. If higher yes. But note i have running Visual Studio 05 (which minimum reqs for CPU 1000MHz
) & Winamp & ICQ client, at that time & i am playing with YaPB (with the msec method, that PBMM use), which eats more memory & CPU.
So i advice to check for video drivers updates, and remove unneeded programs from startup. (it may help).
