Huge FPS Loss

[JasonB 117]

The reason for your FPS loss zoomin into that area as you depicted in your picture has to do with the fact that the camera is zoomed into an area where there are so many parts inside the fuselage (cabin interior, cargo hold, nose gear bay, MLG gears etc) and it is trying to render all those parts in the camera viewpoint, you get an fps hit. When you zoom out, you get a higher fps, that's because the graphics engine is prioritizing the z-indexing meaning what's in the cameras nearest field of view it renders that and what's the next farthest from the camera view, it's rendering that at a slightly less of a priority and so on as the objects get farther away from the camera view.

 

We are dealing with a very old graphics engine in FSX.

 

 

 

Same view, different zoom...

 

FPS - 79.6

 

 

FPS - 5.4

Cheers, thanks for that!

It's actually much worse than that. First, the z-ordering has already been computed and it (should) have already ditched objects you can't see from being rendered. Old or not, this is graphics 101.

 

I just tried here. I'm on the ground. If I set it so the camera is slightly above the centerline of the aircraft, FPS are 60+ (zoomed all the way into the fuselage). If I pan the view so the camera is below the aircraft centerline - I get 5 FPS. SAME ZOOM, SAME ANGLE, SAME THINGS IN THE PICTURE. Just a trashed frame rate.

 

Go figure.

 

This matters very much with the taxi camera, as they are below the centerline of the aircraft.

 

For fun I opened 5 windows with various zoomed views of the external - I get little performance impact. Yet to get the 300ER, but if I can run 5 external views + VC with little impact, then 3 smaller views in the taxi cam should be easy as well (the above finding notwithstanding).

 

Best regards,

Robin.

Hello Tobias, what exactly did you delete line in the "taxicam of panel.cfg" I can not find it? 

It is well located in this folder. SimObjects / PMDG 777-300ER / aircraft (CFG file) If this is not what can you tell me the precise way to get to Taxicam panel.cfg. 

Thank you for your help and good flight my Friend.

How about a screenshot of that, because I think you're kind of full of it...
