PMDG 777 FPS Improvements

The PMDG T7 is finally out of the P3D but performance is quite below average. For example my system gives me 40fps with Aerosoft 320, but only 24fps with PMDG 777.

So here are few tips to get more juice out of it.

Note that I use Lenovo Y510p notebook with 4700MQ@2.8GHz with GT755M in SLI. YMMV.

Of course, backup the original files without fail before you do these modifications.

1. Change panel resolutions 

Edit the panel.cfg (Prepar3D v2\SimObjects\Airplanes\PMDG 777-200LR\panel) to make these changes.

Look for VC section from [VCockpit01] to [VCockpit40]. In each one these is this entry:

pixel_size=1024,1024

Halve these values from 1024 to 512, so that you have:

pixel_size=512,512

You can halve all 40, but I think its enough to just halve the large values like 1024 and 512 to 512 and 256 respectively. Note that one VC section has both values different, e.g. pixel_size=1024,512, so that should be halved to pixel_size=512,256.

2. Replicate Pilot's panel's to Co-Pilot

In the same panel cfg, look for [VCockpit04]. This contains Pilot's and CoPilot's MFDs.

Look for gauge03 line. In this line change the word RIGHT_INBD to LEFT_INBD.

Look for gauge04 line. In this line change the word RIGHT_OUTBD to LEFT_OUTBD.

Now co-pilot MFDs will render same as Pilot.

Note you can also change CoPilot and Center CDUs to render as Pilot's CDU in [VCockpit10], change R and C to L. Not sure if this makes much of a  performance difference.

After these two I get 27fps, up from 24fps. About 10-15% increase.

Same tips should work for FSX version also.

Enjoy!
