I realize that the MJC Q400 is not officially supported for P3DV2, but after I applied the 1.008 patch and hot fix I started to get a very strange problem (a problem that I didn't have prior to the 1.008 patch).

 

The problem: slow motion - frame rates are good - but it's as if the simulation goes into 1/4 speed slew mode

 

I've done the usual diagnostic process, disable everything in EXE.XML, DLL.XML, scenery, etc. etc. to get back to a base configuration, but the problem remains.  The problem seems "random" ... meaning I can be flying for 30, 10, 20 minutes over nothing but ocean, then the enter simulation seems to slow down but I can see my fps remains constant (locked at 22) ... so it's not a performance/fps issue it seems to be related to the simulation rate issue ... as if I switched to 1/4 speed slew mode or something.

 

Problem is specific to the Q400, don't experience it on any other default or 3rd party aircraft.

 

Anyone else having this same type of problem?  Has me puzzled.

 

Thanks, Rob.

Hi Rob,

Are you using FSUIPC's 'auto-save' function? If so, try disabling it, it has been found to cause problems with the Q400. Also, as mentioned on the Majestic forum, try leaving one of your CPU cores 'open'. The Q400 will (by default) try to run on the CPU not being used by the simulator.

  Regards, Craig.

Oh hadn't even thought about that ... I did have FSUIPC disabled as part of my testing ... but good to know, thank you.  I'll try the affinity changes and see where that takes me.

 

Many thanks for the suggestions.

 

Cheers, Rob.
