FlightSim's "RenderToTexture" option
Here’s a little snipet of info that might explain some things to a few AVSim users.
The RenderToTexture option in the display settings is used to control how the cloud impostors are generated. If the setting is on, then FlightSim will use the GPU to generate the impostors (if possible). If it’s off, FlightSim will use it’s own software rasterizer.
The problem people are seeing is that if you replace the cloud source textures with DXT3 textures, then FlightSim will fault if RenderToTexture is off. This is because the software rasterizer doesn’t know how to deal with DXT3 textures. In fact it can only deal with 1555 or 8888 textures, which we assert in own internal builds, but there’s no failure path for the release build.
I guess we missed the fact that end users might replace our cloud textures with their own…
So now you know.

The clarification of these tweaks, and the new areas for tweaking that you've offered are really, really good. Suddenly, what I see in my simulator when I change fs9.cfg makes sense.
Do you have any other "new" variables that we might not know about in fs9.cfg? I'd be really excited if we could tweak the atc or ai in some other ways (for instance - the time-to-disappear value of ai aircraft).
Either way, thanks for a really great insight into FS... It's fantastic to have the MS team openly engaging with us finally!
Cheers,
