Hello to everyone, having problems with missing buildings and trees on approach at FSDT Zurich like I had (and possibly with other FSDT airports).
Last night, I got a golden tip from Andydigital, who runs the forum of VR-Insight (a company, that sells hardware add-ons for FS. I strongly advise to try it out.
Clue is to add a couple of lines into the [GRAPHICS] section of your FSX.cfg file, i.e.:
[GRAPHICS] ------ This line is already present in your FSX.cfg
SHADER_CACHE_VERSION=5
SHADER_PARTIAL_PRECISION=1
ALLOW_SHADER_20=1
ALLOW_SHADER_30=0
HIGHMEMFIX=1
STALE_BUFFER_THRESHOLD=2147483647
The essential necessary text is in red, but the other lines are strongly advised.
Furthermore you could change the line TEXTURE_BANDWIDTH_MULT=40 in the [DISPLAY] section into TEXTURE_BANDWIDTH_MULT=400
If you are interested in this, then you should do a search in Google for the word: HIGHMEMFIX. There is much info about this.
Hope it helps. Anyway, with all the FS hardware add-ons, I've connected to my computer, there is no single problem anymore.
Success and let me know, how it works for you.
Regards,
Henk
