Back after like 2 months, and considering the other topic about perf was closed (gotta love the mods always ...), I will put an answer to my own former question about why my G3258 was slower than my i7, even if the pentium is clocked higher.

It was just the bottleneck of the integrated GPU. I really thought it would be enough to not bottleneck FA, I was wrong. The second I started using a decent GPU, well that damn cheap G3258 was totally competing with my i7.

So all the stuff about l3 cache and all. Just rubbish , at least in that case

I think it was also noted, you'd only see the "actual % difference" if you set priority to high, and untick core 0 for ForgedAlliance.exe affinity. Also to not do this unless you have at least a quadcore cpu. Thirdly, if your cpu is at stock clocks, and only the first core (core0) is running at the advertised speed, and all others are running slower; I can guarantee you'll see a performance DROP; I add this because most CPUs now days only have the first core running at full speed, and the rest running slower, sometimes by quite a bit.

These are threads where Col_Walter_Kurtz gives his same opinion, seen here, repeated everywhere; trying to discourage anyone and everyone from even trying something to gain performance via this method.

What you'll also see there, are different people who have tried/tested this and have gained performance - I encourage anyone with a half decent system that plays large/big games to give this stuff a read.

GPG on mutlithreading FA engine: http://twvideo01.ubm-us.net/o1/vault/gd ... 6589i2.ppt

Also this:

Supreme Commander simspeed is dependent on only 1 thread: the sim thread. Once that thread completely saturates a logical core (or more like 85% of a core's capacity due to the way the engine works), the simspeed will slow down. The reason you are seeing only 2 logical cores worked to the max is because there are only 2 main threads in SupCom: the sim thread and the render thread. SupCom FA actually has 22 threads, but the other 20 do very minor tasks that have little in the way of CPU usage. So at best you can see 2 and a half logical cores being used. With Hyperthreading, one physical core will appear as 2 logical cores so what you are seeing with your hyperthreaded i7 looks fine to me.

Before you go around talking trash about how the Moho engine is poorly optimized, remember that the engine was built in 2005. Back then, dual-cores were the new thing. No one expected quad-cored CPUs to be released so quickly. So making a dual-threaded engine where the game simulation and graphical rendering could be processed on separate cores was very innovative for the time.

Not only is this manual affinity method not for fast dualcores suchs as the G3258 which reportedly runs FA at +1 an hour into a Setons game but you might also disturb the OS managing threads on a quad. After all you're telling the OS to use 3 instead of 4 cores for FA decreasing the available resources. It's worth noting these things instead of spreading this method as some kind of general performance increase.
