Flight.CFG file: Terrain LODRadius setting

Recommended Posts

Hi,

I'm attempting to change the [Terrain] LODRadius=3.5 to something else (like 4.5) in the Flight.CFG file, but after making the change and running Flight, it reverts right back. Has anyone had success at making changes to the file and having them stick? It seems as though the 'Cloud' has control. Or this dark colored IPA is kicking my brain around.

Thanks for reading,


Greg G

In the Flight.cfg file, look under configuration, there you will see a line that says " custom = 0".

You need to change that 0 to a 1 and save.

 

Then your changes you make in the flight.cfg file will stick, and graphics settings in the game gui will be greyed out.

 

I would also add, you should make a backup of the original cfg file to have just in case...

Thanks a lot Don, that did it. Don't know how I missed that one.

 

Cheers,

You are very welcome, they added that option in one of the title updates to allow finer user control of graphics settings by overiding the ingame settings.

I would add that the general consensus so far seems to be that the game is so well balanced as is, that most people report worse performance when fiddling with things.......

I find that LODRadius=4.5 looks quite a bit better than the default 3.5, basically moving the blurry textures much further away with no effect on performance. 6.5 is incredible, but the scenery loads much slower.

 

It's so nice that we all get to choose whether to fiddle or not...

 

cheers,

In spite of the enormous problems that tweaking has created in the past, the developers have always chosen to let the user decide what he wants to do.

 

I have not bothered to change anything, except to eliminate the Destination Marker, and LOD 3.5 is reportedly greater than 4.5 in FS X (at least, I think that one of the devs mentioned that), but if you like it and still get good performance, then that is your gain. Good for you. :smile:

 

Best regards.

True. Saw it in a dev post on steam..I upped my LOD by 1 and can confirm it makes a difference, especially when flying low'n'slow..Coupled with a tiny bit of tweaking of the various shadow and detail settings in the cfg and it's like I've flipped a switch and got a graphics update!

 

I find it's the shadows that kill my machine for some reason...

Can you tell us what the tweaks are, so we can get a tweaking lesson for Flight? Just like FSX, tweaking lessons are great in Flight!

That is interesting, as I use 6.5 in FSX and find it the sweet spot regarding scenery texture displays. Are you saying a lower figure is more demanding than a higher one?

No, I'm sure the higher number is the further out you see the more detail, and therefore requires more PC cruching power to run. I think the MS Flight dev was saying the scales for FSX and Flight are different and 3.5 in Flight in actually something greater than 4.5 in FSX if compared directly.

Excuse me, Greg, I was not very clear, was I? LOD 3.5 in Microsoft Flight loads more high resolution ground textures than LOD 4.5 in Flight Simulator X.

 

The developers increased the resolution of distant terrain in Flight, I imagine because they wrote new code for graphics display that would allow for better performance overall.

 

Best regards.

OK, that makes sense now and thank you for clarifying!

cheers all,

I did LOD 4.5, loading time was 5 secs slower than LOD 3.5. Then I tried LOD 5.5 and it was 2 minutes slower than LOD 3.5. Seems like 4.5 is the ideal LOD.

I just tried 6.5 LOD and while it doesn't really slow down loading the scenery by much, it seems to limit my FPS at 30 instead of 60...

 

I saying it's self limiting because it runs at 30fps no matter where I am or what I'm looking at. Note that I use triple buffers to avoid this so I'm not sure what setting in flight.cfg to change to undo this limit. (If indeed it's FLIGHT doing the limiting ;) )

 

UPDATE: Fixed. Had to remove the VSynch from FLIGHT and only use D3DOverrider to vsynch + triple buffer.

Turns out that 6.5 lowered my FPS from 120+ to around 50 ;). Switched to 5.5 and now all is well at 60 everywhere.

 

LOD makes a very nice difference I must admit.
