Multi core Utilization-part 1

CPUs and GPUs all have at least one processing core. A core is an area for processing a program through the computer chip. Some chips only have one core. Two, three, four, and more are possible in a computer chip.

Using Multi Core is something to try, though many IL-2 users are best served by assigning IL-2 to run in a single core other than core #1. Other IL-2 lovers are seeing good improvements with IL-2 operating in two cores, preferabley other than core #1.

IL-2 can be set to run through two CPU cores. For my simulation, this was made practical with the use of nHancer add-on to nVidia. ATI users might find this post interesting, but of course you may skip it and go to the next. Recommended is that everyone examin my whole topic for much useful information. More ATI information is further in the topic and more will be adding in the future. Big Grin

The simulation runs in the first core by the factory setting which it shares with your Operating System, hence the decrease in allowable graphics settings and performance. Commanding IL-2 to run in two cores, or at least a different core, will free processing power and result in your being able to increase visual quality and overall IL-2 performance.

The proof came for me when I went from only one or a few threads in my first CPU, according to Task Manager-Performance Monitor and Resource Monitor, to 18-28 threads in both cores. This is obviously a multiplying factor of severalfold. Now my graphics settings are set by me above the NVIDIA stock available ones-a super high increase! The visual improvement is stunning. Some scenes look exactly like real life. I still have good performance, no mouse delay, and no joystick delay. My Frames Per Second is satisfactory in the most demanding situations.

Note: Tri Core, Quad Core, and newer chips with even more cores than that-beginning in 2010-might run best with different core assignment. For example, many Quad Core users mention that they run IL-2 very well in only one core. Some are assigning IL-2 to run in the four core alone. All other programs such as TeamSpeak which they use with IL-2 are being assigned to a different core than IL-2. This increases the performance of the simulation.
