Never bin happier with my setup

Recommended Posts

Hey folks and friends,

I am in a winter temperature envelope making my sim so smooth (P3Dv4.1)  that i almost cant believe my own specs. :biggrin: . For starters i am only with SLI 970`s in 4K but thats okay as long as i dont push Dynamic lights to the end .

Right now i am still fiddling with an Haswell 4770K and ProcessLasso trying to make ground textures even sharper without getting to much heat.

I know and can tell that HT ON is improving ground texture handling .

Right now i disabled the last core two cores via Lasso in HT mode and so far temps has dropped 25%

Still a smooth ride between KSDF to KDEN as SWA 3918 :biggrin: 

 

So what is your settings ?

Benefits HT off or ON

VFR ?

IFR ?

 

Thanks

 Michael Moe

Happy for you Michael :biggrin:

4 cores HT ON 

IFR  ofc :biggrin:

NO AM for v4 as Steve w says not and that I dont question. But I do kick everything else of core 0 -1 I/E ASv4 etc.

6 core - HT off

With v4.1 HT off is performing better than HT on.

AM=62 —> 1,1,1,1,1,0

–> 4.3-4.3-4.3-4.3-4.4-4.3 Ghz

Addons on core 2 and 4.

IFR

6 Core with HT on, which certainly helps with terrain loading (OC'd to 4.6 day-in day-out). No AM. Frames unlimited with Vsync @ 1/2 refresh rate.

VFR and IFR.

Cheers!

My recipe for success in P3D v4.1 is :

4 core - HT Off (lower temps, less stutters)
Overclock at 5.0 Ghz 
Locked FPS in P3D at 31 
30Hz refresh rate monitor
FFTF=0.01 tweak in .cfg

My specs are on my signature.

HT on and then an AM that removes processing from logical core 1, that's what causes the HT stutters in my experience.

That's what I use with my i7 3770 and my stutters are gone.

4790K@4.5 HT on.

AffinityMask=254  // 11 11 11 10

run a .bat to start ASP4, PE & FSXFlight with Affinity 1  // 00 00 00 01

4790K @ 4.8 HT On.

AffinityMask = 244      11 11 10 00

Run ASP4 and a GTN on Cores 0 & 1

GA only IFR/VFR

i7 7700 4,2GHz (HT enabled)

Prepar3D v4.1 is running on all cores (1,1,1,1,1,1,1,1)

KFA2 GTX 1060

Usually flying the PMDG737 and I get 40-60FPS (on very complex scenery it drops to 30 FPS)

Thanks. Is this the other way around vs my test with core 7-8 off via Process Lasso? You have P3DV4 off logic core 1?

Thanks Michael Moe 

PS Process Lasso remembers my affinnity settings for addons which is very  nice. I dont use its performance profiles though

Specs in my signature, HT off: For some reason it's smoother under more demanding scenarios.

The only tweak I use is "OPAQUE_SHADOW_TEXTURE_SIZE=4096" to improve my shadows.

Monitor is 144hz which I don't particularly recommend for P3D, though I've had no problems with it.

start /B "" /affinity 1 "D:\User Programs & Data - Bruce\FSXFlight\FSXFlight.exe"
start /B "" /affinity 1 "C:\Program Files (x86)\PilotEdge\pilotedge_p3d.exe"
start /B "" /affinity 1 "E:\AS_P3Dv4\AS_P3Dv4.exe"

Starting my add ons by double clicking a .bat file with these three lines puts these add ons on LP0 (rightmost) and my P3Dv4 AM of 254 avoids that LP.  These add ons don't use much CPU time so this works for me.  YMMV.

This is tricky... you actually do not want to share a physical core between the main P3D thread and your addon apps.. if you can avoid it.  So keep Core 0 free if Core 1 runs the main thread.

I might direct the addons to Core 2 or 3 in this case.

OR, choose the example above:

AffinityMask = 244      11 11 10 00

Run addons on Cores 0 & 1

Yeah, I have heard that from LM, Steve W & others.  So I tested my system with AM 244 and .bat affinity 3 and then again with 254 and .bat affinity 1 and the latter gave cooler temps and better performance.  Maybe because I have an "older" GTX 970 GPU and I need the extra CPU LPs to compensate.  I don't know but I do know it works well for me.  Again ASP4, PE and FSXFlight are pretty low key apps so the CPU utilization is like 5% most of the time.  Almost like not sharing the Core 0 with the main P3D thread.

Maybe I am misreading this, but 244 should not be coupled with bat affinity 3, but rather 0 & 1

.bat affinity "3" would be 00 00 00 11 and 244 is 11 11 01 00.

Do you really see a measurable difference using this affinities for the additional softwares? I mean, I do not see any difference at all in my fps, no matter if I run only P3D alone, with AS4 in the background or with AS4 and Pro/ATC-X. Those two addons need that little CPU power... My FPS stay the same, no matter if I turn on or off AS4 or Pro-ATC/X in the background. This with AF=85 for my 3770K@4.5.

I watch FPS but I really use logs of CPU / GPU temps & utilization % along with overall smoothness on test flights out of an intense airport scenery over a similar track.  I don't believe I've tried AM 85 with no .bat affinity for the add ons.  I'll try to get a log sometime today (US east coast) and post.  I think a lot of this depends on so many variables...  I run unlimited frames, 60Hz monitor refresh, vsynch and triple buffering on, etc...anti aliasing is also a variable.  So as I said before YMMV.

Is is not an fps thing, but a smoothness thing in my experience.

Any thing you can do to give P3D as much room as possible contributes to smooth stutterfree flight.

The only that is not fixable, as best I know, is a sudden halt, when flying into a new detailed scenery region in Orbx land, that requires a lot of new textures to be loaded.  It would be nice if LM could figure out a way to handle this in the background.. :cool:

+1  My experience is much smoother and CPU runs cooler (2-5C with less temp variations) when I separate all other processes from the sim.  For example, my GTN grinds to a halt if it runs on any LP the sim runs on.
