Addon aircraft performance and affinity mask tweak

Recommended Posts

I will be buying FSX:SE in a week or two and will buy my first payware aircraft. The system I'm going to be running it on isn't a tank like most of your PCs. I was wondering which aircraft is easier of the frames..Aerosoft's NEW a320/321, iFly 737 or PMDG 737.

 

Also I've been poking around elsewhere and came across the affinity mask tweak and how it supposedly allows FSX to use more cores? Can someone clarify this for me, I'd be very grateful

fps wise the Airbus and the PMDG 737 should be on the same lenght. Can't speak for the iFly 737 tho.

 

How are your navigation skills? The Airbus is more user friendly, and you might enjoy more the automatic checklist it has with the copilot. 

For affinity mask and other tweaks to fsx.cfg check this pdf :)

Welcome to the forum. Be sure to check the SE compatibility of any complex aircraft before installing it. The developers are working hard to get caught up but there are still some problem spots (the PMDG 737NG is currently one of them). I'm sure all this stuff will be sorted out in the next few weeks but, in the meantime, just be aware that there are some issues yet to be resolved. Again, welcome.

My navigation skills are pretty good. I haD the QW 757 on my boxed FSX. I just feel the need for something a little more complex.

Thanks for the welcome Doug. I was afraid of forums before haha. I forgot the NGX doesn't work with SE yet. I'm being drawn toward the Airbus because by all accounts I heard its better on frames, plus it has an installer for SE. Saves me the headache.

PMDG 737NGX is not current available for FSX:SE  (although they are apparantly working on making it compatible), so that may sway your choice.

 

Personally, I think the iFly is miles behind the other two, in terms of visuals, modelling and texturing.

 

So I'd recommend the Aerosoft Airbus A320/A321 (or A318/A319) which has a native installer for FSX:SE and runs great on it.

 

[EDIT:  Oops, just read the bottom of your last post and see that you already spotted the above points! :smile:]

FSX:SE will automatically set the AF internally to work best on your system...

 

My advice? Forget about "tweaking" and spend more time flying! :Whistle:

Nice. Which is better on frames? PMDG 737 or aerosoft's a320?

Setting an Affinity Mask, restricts the number of cores that FSX can use, it does not enable more cores..

 

The main reason is to free up a core for Windows to do it's thing without tripping over FSX.

 

So, for a quad CPU:  one core for Windows, three cores for FSX.

 

With hyperthreading enabled: two cores for Windows, six cores for FSX.

Ah, I see. So you'll get more cores to work with with an Intel processor right? Since AMD doesn't have hyperthreading?

Yes, but the value of hyperthreading for FSX, is not clear.  Many i7 users, myself included, have it turned off.

I see. I'm getting a dual core i5

 

What kind of processor is that?

I beg to differ with you on this. That may have been true prior to Windows 7 64 bit, but the OS task scheduler in Windows 7 (and especially Windows 8) does a more efficient job of partitioning CPU resources than any human can do manually. There is not a "Windows core". All that happens when one uses an AM to block either FSX or P3d from using a core is that the flight sim app has no access to that core, which often makes performance worse. The OS scheduler continues to put other threads on all available cores, including those being used either by FSX or P3d.

The main reason for the AM in FSX/P3D is to ensure threads don't double up on cores in HT mode.
