Tweaking

Recommended Posts

Anyone tried any old CFG tweaks from FSX in P3D2 yet?

 

i.e things like texture_bandwith_multi= etc...?

Afaik none of them work in P3D 2.0. The only 'tweak' that seems to work (for some) is the Affinity Mask one. All others have become obsolete.

Really? I did not know that! Thanks!

 

And here is me thinking if I change texture_bandwith_multi=30 to 100 it would work ha!

Well, if the option is in the cfg, like the one you mention, it does of course WORK ^_^ but (again afaik) you won't have much (if any) benefit from changing the setting like you would do for FSX because P3D 2.0 simply is a different beast.

In the P3D V2 "Learning Center" they mention these tweaks to experiment with:

 

-FIBER_FRAME_TIME_FRACTION=0.33 (Lower this for increased performance, but also increased chance of blurry scenery)

-SWAP_WAIT_TIMEOUT=30 (Not sure what values can be used)

 

[JOBSCHEDULER]
AffinityMask=14    14 is the value recommended by Lockheed Martin (3 cores), some find 15 to be good(all 4 cores)

 

I see that TEXTURE_BANDWIDTH_MULT is set to 30 in P3D V2 while it defaults to 40 in FSX. In FSX most will prefer 80-120, but I doubt it has any effect changing it in P3D.

I get the same results using the stock CFG in P3D 2.0  or adding [JOBSCHEDULER] AffinityMask=14  setting. About 35-40% CPU usage max and 46 threads on an I7-3770K OCd to 4.3Ghz. 

 

However, when I set [JOBSCHEDULER] AffinityMask=15, I get worse performance - 20% reduction in FPS, the same amount of threads, and 50% CPU usage.

 

For me, leaving at stock for now works the best, but it seems like there is a lot of room for improvement of cores/thread usage in P3D that is waiting to be tapped.

I ran Bojote's tweaking website on prepar3d.cfg. It made lot's of tweaks, but I didn't see any change in performance.

That site is completely obsolete for FSX, much less P3D. It adds way too much stuff that isn't applicable.

It may be obsolete, but I find that it still works great for me. But then I am obsolete according to my wife and kids, so there you go!

hi guys I have a question: when I'm in Prepar3Dv2, ground sometimes the screen goes black entirely can be due to this?

 

Thanks in advance
