The resampled ground with fs9 bglcomp detail layer is very clever and great for performance. One question -- why wasn’t the fsx bglcomp used?
The ground detail layer is not made with bglcomp, not even the FS9 version. Is made with BGLC so, strictly speaking, it's using FS2002 commands, which are *still* supported in FSX, as part of the generic backward compatibility engine. That's the only part in JFK were we don't use the FSX SDK.
Judging by your early Las Vegas preview shots it appears you’ve abandoned this technique for the fs2002-style ground, as with Geneva -- why is this?
Geneva use an even different method, which DOES allow for rain effects, and it's an hybrid AFCAD+FS2K ground+detail.
The reason for this are:
- We can control sharpness better than having to rely to users knowing how to configure their settings, like in case of the native photoreal FSX ground. So, even if the user has wrong settings, the scenery would appear reasonably sharp, so we don't get complains of the scenery being blurred by user that can't set their settings.
- Geneva is smaller that JFK in area. Applying the Geneva method to JFK would have too much of an impact on fps. First, second and 3rd priorities for JFK were fps, fps and fps...
We'll see how KLAS will come out...
