I believe there are two approaches that work..

 

You can change the Affinity Setting to accommodate the Q400, AM=7 works best for me..

 

Or, you can keep your favorite AM setting, AM=14 for me, and change the Q400 ini file.

 

Try this:

 

disableFSXCPUBypass=1

systemThreadsCPUMask=1

graphicsThreadCPUMask=1

 

Sorry to resurect this old thread but is the advice here still good for AM=14 in the FSX.cfg?

 

I should edit the Q400 .ini file as suggested to get the best Q400 performance?

 

Thanks,

I think this is old information..

 

Not sure, but I run with AM=14 and the default settings in the ini file.

Hi,

I'm experiencing stutter just during the taxi, otherwise all is running like a charm with a stable and smooth 30fps.

I want to know what settings should be change ?

FYI I've got a i5 2500k 4.6ghz (4cores and affinitymask set to 14)

Thanks !

Is this at a complex airport?

 

If so, that may be the issue, and no settings in the Q400 will fix that..

Yep at a complex airport, but all my PMDG, Qualitywings or A2A are running fine without stuttering.

 

The Majestic Q400 is for a majority of simmer one of the smoothest complex aircraft, I'm pretty sure I have to tweak the ini file, maybe the CPU Bypass line ?!

Well, this sounds like a question for Majestic - have you asked them?

Not yet, I will. 

I tried here by chance because I think the issue is the affinitymask.

Thanks for the answer Bert, have a good flight !

My goodness. This place never changes - everyone has an opinion - no one has an answer.

 

How many times can Bert ask a simple question and get no answers ?? !!

 

OMG. LMAO.
