cFosSpeed Game Analyzer

Online games can be demanding. If you are in an important boss fight with a lot of action, players, and monsters on the screen and somehow the action gets jittery, the question is: Why?

Does your Internet connection have too much latency? Is your CPU or one of its cores at its limit? Is your graphics card the limiting factor? Do you have too little system memory so paging slows your PC down? Does some program in the background unexpectedly use a lot of Internet bandwidth?

cFosSpeed Game Analyzer helps you to find out. After a demanding event, you can open the Game Analyzer page and see a history of the most important performance statistics of the past 5 minutes.

The "Ping Stats" graph shows cFosSpeed's ping measurements of your Internet connection to the next hop, i.e., it displays if your part of the Internet connection is congested. The colors green, yellow and red indicate how high your ping is. Blue dots indicate the RTTs to TCP connection endpoints. They are high, if the destination server (e.g., the game server) answers slowly or if the route to it is congested.
The "CPU Usage" graph shows CPU utilization in green and the maximal utilization of a single CPU core in light green. Sometimes games cannot scale well across multiple CPU cores and one core becomes the limiting factor.
The "GPU Usage" graph shows the utilization of your graphics card.
The graph "Line Speed" shows the amount of receiver and transmitter traffic from and to the Internet. This graph allows you to see if Internet bandwidth is used up while you are gaming. LAN traffic is not the issue here, since the bandwidth of the network adapter is typically far greater than the bandwidth of the actual Internet connection and high LAN traffic can be handled by your system without impacting the Internet connection. Thus, only Internet bandwidth is displayed. Please note: The cumulative traffic of all PCs with cFosSpeed installed is shown in this graph by means of cFosSpeed's net talk feature.
Finally, the last graph labeled "Page faults" is an indicator of how often the system has to swap a memory page to or from disk because physical computer memory is used up. This can degrade overall system performance, especially since games are known for their appetite for memory. A few thousand page faults per second are normal, because of the way the operating system organizes its virtual memory. However, several 100k page faults per second are suspicious.
So, play your game and when things don’t perform as expected, cFosSpeed Game Analyzer has the most important readings at a quick glance, especially after a big fight.
