Good Framerates - major stutters / pauses

[JoeFackel 760]

You can further investigate with an sophisticated task manager like AnVir, maybe that helps you to get a picture.

But, on another hand....not sure why I don't have NCP anymore...LOL. Could that be deleted by itself after updating driver few days back....? It seems that my PC has a mind ob it's own😋

 A hundred years ago I had these little errors, changes, weird issues that would crop up every few days and nothing had changed either.  Turned out the hard drive the OS was on was slowing failing.

As of now I can't see any indications of any failure, but  possible and I am hoping that technology at least made impact on quality, but like everything else, cheap production, incompetent people made errors in the process. Who knows.

What I suspect is that I have issue with QW, why, I have no idea, I see some flickering with instruments as well. Maybe I am right but I am currently in the air and will check with stock AC to see what's happening. But it is very odd that I suddenly started experiencing this issue and I had none whatsoever.

The relevant point is whether those extra logical processors are doing useful work... the kind of work that enhances the simming experience.  Which in itself is no easy metric to determine since each of our sims/computers is configured uniquely differently.  Kind of makes hay of the arguments of those who claim HT should always be on and those who claim HT should be off.

When you can do more work at the same frequency then it's the same heat because with HT off there's cycles unused making the same heat. The reason folk get too much heat is because they allow too many LPs not because HT is on. Look at a 10 core HT on no AM = 20 LPs most of which do more than you need because they are background tasks. You need the fastest main task core, then you feed that with the most work done to bring in the data, without letting that overwhelm the system which brings the main task  down. It's basically not understanding how the simulator works and how HT works that gives HT a bad name.

Major stutters are something else, like as the others have stated, maybe a problem elsewhere in the machine.

My point was largely rhetorical but to simplify, how does one determine if the extra LP's are actually doing something to add to the simming experience.  The reality is that just because a tool can do more work (such as a CPU with HT on) doesn't necessarily mean that work is useful (adds to the simming experience).  There are so many variables involved in that determination, not the least of which is the subjective impression of each simmer flying their unique configuration on their unique hardware, as to make a discussion of HT on, HT off, Affininy Masks. yada yada clear as mud.

Quite simply, what works for one may not work so well for another... depsite your claim that HT on accomplishes more work (no dispute here about your claim).

Very easy to spot that your scenario loads faster with HT enabled. If the scenario loads faster what is at work there? It is composing the scene faster.

If it composes the scene faster does it mean less stutter? Maybe. But not if by utilising too much of the system to load files and compose the scene it overwhelms the system bringing down the fluidity of the main task.

So there must be an optimum number of cores/LPs for the background to do its thing and leave the main task running smooth.

Add LPs one by one to the AM and the scenario will load faster and faster. At some point the decrease in loading time is very small, that means the system is saturated and we use too much. There is an optimum amount to look for. Using No AM with many cores it really become a problem.

[SteveW 1,792]

With the major stutter problem I would install the simulator stock set up the AM so as not to use too many cores. For example If I'm using eight or ten core CPU use just six HT disabled AM=63. Run the Mooney on a flight between two medium scenery areas - no addons whatsoever. Check for problems. If no problems move on from there. Do that to get a baseline performance so you know the system is OK.

Are you sure you dont have NCP? right-click at desktop doesn´t show the option?

Maybe an old Nvidia driver was installed by windows itself?

I would also default Nvidia driver before running any tests. Install GeForce Experience, check for updates, download latest driver and use Express Installation. Next Select Nvidia Control Panel and in 3D settings Restore/Apply the global profile, then Restore/Apply the Prepar3D.exe profile.

I have written about my experience which I think corresponds to Steve's guidance.

HT ON means my CPU generally runs with fluidity, but running P3D with on all cores we end up with a hotter CPU. To counter the temp issue I run Process Lasso and allocate P3D to the HT OFF cores (for me 0,2,4,6,8,10) on my 11 core PC (I think these are the physical cores). I then allocate all the rest of the programs on cores 1,3,5,7,9,11. Better temps and fluidity and better CPU utilisation.

As I live in a warm climate, to counter the temps in summer running P3D, I also remove the CPU cover to allow it to breathe 😃

Also - keep everything else off of LP1 so that LP0 has maximum bandwidth of core zero.

So I should run P3D on cores 0,1,2,4,6,8,10 and default everything else to 3,5,7,9,11?

[SteveW 1,792]

Yes. Also you could corral those other apps even higher, 5,7,9,11. Background tasks take seconds to complete so they can better afford to be stalled by other activity on the core. Whereas the first task on core zero LP zero should not share. The second task can also benefit from not sharing to a lesser extent.

I will check it out although I suspect if I use the non-physical cores (1,3) then temps might go up. Thanks.
