If the server has more than 8-11 people he begins freezing on 0.5-1 second, and this is repeated again and again at regular intervals (29 - 32 seconds).
This is quite evident through HLSW:
In this screenshot is not very visible, just a couple of people on the server.
SSD Vertex 4 128GB
AMD Phenom II x6 1075T (Upped to 3.7MHz)
24GB RAM DDR3
Falcos Prop Protection
Easy Precision 0.95
Adv Dupe 2
There are any suggestions? Thanks.
