This worked great on my PC

[Moxica]

The "pi_server.exe" use a lot of CPU. Often as much as 20%
And on my PC it uses core#4 -same as main core for DCS.
This caused my CPU to max in almost all my DCS sessions.
So I re-installed process lasso, and made sure pi_server.exe has no access to this core.
Voila!

Nice! But Voila what? I mean, did you experience any practical improvement during gameplay? Higher FPS?

I installed process lasso on another PC than this one some time back. All it did was leaving me confused. Not sure what I was actually doing or if it improved anything at all. So, I uninstalled it. That was on an Intel CPU based PC. This new here is AMD 9950x3D. Not sure if it (lasso) will actually do anything. I feel I have smooth gameplay, I don't experience stutters with my Crystal Super.

If it helped you - good.

No more max out of CPU.
I thought that was obvious.

That part, yes. But since I dont't experience stutters, freezez and such now... what do I gain?

Then this tip is not for you.
There are a lot of other people seeking better performance.
I also thought that was obvious.

Nope... I'm kinda slow sometimes..    And I am sure your advice is well appreciated by those who do need it, seriously

But, 20% usage by the Pi service is a lot I think. But since my experience in computer programming is from programming The Vic 20 from Commodore in Basic, in the early 80's, I don't know much about how different programs use different CPU cores. For example, will the Piservice app always use the same core unless you use Lasso, or is different from system to system (even if they would have the same CPU I mean), or can it be different on the same system from time to time? I know this is way outside what we are discussing here, but.. For example, NOW I don't have problems - maybe that is because on my system Piserver is not on the same core(s) as DCS? And could I experience booting up my system one day and suddenly Piserver has moved over to the same core as DCS and impact performance? 

I have tried so many "Voodoo, Karate, Judo and Ninja" tricks on my PCs over the years to get them to run flight simulators better... And many have just been placebo when really looking in to it. Your advice is obviously NOT placebo since it's easy to see that they were on the same core and things improved when spreading them. I think I can remember, after the Falcon 4 launch in 1998, I also became semi-religious for a while, saying prayers hoping Falcon4 wouldn't crash...  That was a nasty one...

As I understand it, a multicore CPU has a main core. Heavy programs seek to use it, because it is faster than the rest.
On my system, I found that during problematic performance periods, my Core#4 was maxed out: 100% usage.
There was a clear correlation between high stress on that core and a bad flying experience.
It was easy to see that piserver.exe was going kinda rogue at times, AND using that same core.
I mentioned the symptoms in an earlier thread before I knew what caused it with: "Sometimes DCS wakes up on the wrong foot/side of its bed." (or smth. like that)
It was not problematic on every "session" but so often, I was hesitant to even start DCS.
Now it is stable, and beautiful, and best of all: It stays that way.

(By the way: I'm considering a Buttkicker, but I'm on the 2nd floor, and I wonder if it makes any noise downstairs?)
