Bufferpools=0 and hyper threading=On

[Mike_CFII_MEL 789]

Hi,

 

Never been able to get Bufferpools=0 working on my friends computer until tonight.

------------

His setup

------------

I7- 980 @ 3.4GHz, 8 Gig Ram, 2-GTX 480 video boards (running three monitors surround / 5760x1200)

 

He is running numerous (airports,aircraft,weather) addons. Up until tonight, I have never been able to get his system to work with the Bufferpools=0 tweak. His computer would always crash as soon as he started his descent into the arrival airport, as soon as the arrival airport loaded into memory, his system would freeze/crash.

 

Well tonight I decided to try and use Hyper Threading, so far that has enabled him to take advantage of the B/P=0 tweak, without P3D crashing/Freezing.

Test Flight

Aircraft: PMDG 737NGX

Departure Airport: KJFK (FSDT)

Arrival Airport: KPHX (FlightBeam)

AS2012 (via Network)

FTGACARS (via Network)

P3D Entries

---------------

[bufferPools]

Usepools=0

 

[JobScheduler]

AffinityMask=1364

 

[Main]

Fiber_Frame_Time_Fraction=0.15

 

So far, so good. He is seeing better performance with the B/P=0 tweak with no crashes so far...

 

Just thought I'd share, maybe someone out there is in the same boat as my friend and may be able to use the tweak.

Not bad but suggest you may like to take another look at the AffinityMask setting. This thread at LM is quite informative. Mine is set to 84.

Hi,

 

Core

0 1 (1st. physical core)

1 2 (1st. logical core)

 

2 4 (2nd. physical core)

3 8 (2nd. logical core)

 

4 16 (3rd. physical core)

5 32 (3rd. logical core)

 

6 64 (4rd. physical core)

7 128 (4th. logical core)

 

8 256 (5th. physical core)

9 512 (5th. logical core)

 

10 1024 (6th. physical core)

11 2048 (6th. logical core)

 

So: 4 + 16 + 64 + 256 + 1024 = 1364 (the last 5 physical cores of a hex core with HT enabled)

Computers are weird animals! I used to run my i7 920 o/c to 4.2 with HT turned off. After a fatal FSX crash, I then started using P3D. Now I'm running P3D at 3.8 with HT turned ON and with no use of the Jobscheduler tweak, and it's smooth!

 

Can't explain it, but it's working lol.
