If you have upgraded FS2004 to FS9.1 using the FS2004 Update available from the FS download site, you will need to set TERRAIN_MAX_VERTEX_LEVEL to 21 in FS9.CFG. For some users this is all the information you need to know, but others may need more detailed instructions.
IMPORTANT: The full 19m resolution is not needed by most terrain sceneries. VFR Terrain is unique in fully exploiting the new capabilities in both terrain mesh and vector features such as detailed coastline and lake shorelines, certainly on a national scale. If you do not have VFR Terrain or a genuine high resolution mesh or vector scenery, you do not need to enable 19m resolution.
You do not need to set 19m for any other UK terrain scenery apart from VFR Terrain.
ENABLING 19m RESOLUTION IN FS9.1
Note: You need a certain amount of computer skill to do this, but nothing beyond the capabilities of most users. You do however undertake these instructions entirely at your own risk.
Step 1
Find FS9.CFG at one the following locations:
Windows 2000/XP:- <windows_system_drive>:\Documents and Settings\<username>\Application Data\Microsoft\FS9\FS9.CFG
Windows 98SE/Me:- <windows_system_drive>:\Windows\Application Data\Microsoft\FS9\FS9.CFG
Note: If you are browsing or searching to find FS9.CFGG, you will need to ensure that Tools, Folder Options..., View, Show Hidden Files and Folders is selected in Windows Explorer or My Computer. (Change back afterwards for safety reasons).
Step 2
Make a backup copy of FS9.CFG, then you can always go back and start again if necessary.
Step 3
Exit FS2004 if it is running.
Open FS9.CFG using a text editor such as Notepad.
Search for TERRAIN_MAX_VERTEX_LEVEL in the [TERRAIN] section.
Change the existing value (it will probably be either 19 or 20) to 21.
Step 4
Save the file, making sure that Notepad does not add .txt to the file name. (After saving right click on the file and select Properties from the pop-up mouse menu to check the file name is correct, i.e. FS9.CFG. If it isn't, cancel the properties page, then right-click and Rename removing the .txt extension).
Step 5
Restart FS2004 and enjoy the additional resolution you have now enabled.
PROBLEMS?
If you are unsure of the instructions, please let me know.
If you find you need to revert to the original FS9.CFG, you can revert to your previous settings by restoring the backup copy of FS9.CFG you made in STEP 2.
Alternatively you can revert to an original version of FS9.CFG by pressing Ctrl-Shift while starting FS2004 or by using the Reset Defaults menu option from the FS2004 troubleshooting menu:
Start Menu, Programs, Microsoft Games, Microsoft Flight Simulator 2004, Troubleshooting, Reset Defaults
If you reset the original settings, you will have to re-enter any changes you have made to your FS2004 settings/options since originally installing it including re-running FSConfig if you have used this utility (as recommended).

| I've got Windows XP Service Pack 2 and the Application Data folder isn't there anymore, they got rid of it. Where, in that case, would I find the FS9.CFG file? |

Found it. The folder was there all along. I opened my C drive, selected Tools from the tabs at the top, selected Folder Options and then View to set it so all hidden files and folders were visible. Hope this helps anyone else with the same problem.

So to be absolutely clear about this.
I run msfs2004 with the 9.1 update.
I also got VFR Terrain (+ VFR photos).
So I need to change to value TERRAIN_MAX_VERTEX_LEVEL 21? in fs9.cfg to enable the 19m mesh??
My TERRAIN_MAX_VERTEX_LEVEL is already at 19.
Ps where is the logic in this?? :)

If the FS9.CFG setting was TERRAIN_MAX_RESOLUTION_IN_METRES=19 you might have a point.
However, it's not. It's specifying a 'level' rather than a resolution, so to satisfy your desire for absolute clarity (and hopefully banish your incredulity), here's the Visual Flight Guide to vertex levels in Flight Simulator:
Vertex Level
Vertex Level refers to the distance between adjacent East-West or North-South vertices as they are displayed in the scene. As with LOD, increasing Vertex Levels correspond to decreasing distance between the vertices and therefore increased resolution in the displayed object or feature.
The following table shows this relationship:
Vertex Level, Resolution, Equivalent LOD
19, ~76.4m, LOD 9
20, ~38.2m, LOD 10
21, ~19.1m, LOD 11
22, ~9.6m, LOD 12
23, ~4.8m, LOD 13
TERRAIN_MAX_VERTEX_LEVEL is the Flight Simulator setting which defines the minimum East-West and North-South distance between adjacent vertices as displayed in the rendered scene in Flight Simulator.

John - many thx.
I just assume downloading the patch would automatically do this or even the patch would mention it in the read me after al it was one of the features trumpeted.
Incredulity was aimed at MS and was the result of too many tinnies!

| Having spent a small fortune on various aeroplane downloads, VFR Photographic Scenery and now VFR Terrain, its disappointing to find that my copy of VFR Terrain is out of date because I cannot use my SF2004's 19m resolution. I bought VFR Terrain in order to enjoy "flying" the simulator and not to fiddle around with FS files. So come on Visual Flight, lets have a download to optimise VFR Terrain for people like me with no computer skills nor any desire to learn them. |

Me too please, I am not really competent or cofident enough to fiddle about with files. Today landing at LHR, scenery very blurred and rnwy appeared at last moment. When first loaded VFR 1-4 and terrain, all was very clear and I loved the western approach into LHR.

I'll see if I can incorporate this into an update of FSConfig, and easy to use configuration tool for FS2002 and FS2004. Stand by on this.
I'd like to reassure GTH that his version of VFR Terrain is not out of date. All copies of VFR Terrain contain the full 19m resolution, so it's just a question of configuring FS2004 (with FS2004 Update) to make best use of it.

I'm up and running with your 19m add on to FS Config. No FS addict should be without it. All's right with the world.
Thank you John |

| When I bought VFR Terrain recently the manual said to set TERRAIN_MAX_VERTEX_LEVEL to 20 in the FS9.cfg file. It then warns you not to set this value higher. Am I correct in assuming that this only applies to the basic FS2004 and it should be set to 21 if (and only if) the FS9.1 patch is installed. |

Enabling 19m resolution in FS9.1
