I just have to get used to the way of enabling Rembrandt :-( I though it was enables but it isn't - I believe I'll get even better results after that!

 

If you're using the launcher, in the advanced menu there's a properties dialog where you can enter various property based settings. To enable Rembrandt in this way you would enter: /sim/rendering/rembrandt=true

 

I only played with Rembrandt a little bit, but it seems to be a performance killer for me. I also didn't really like cockpit shadows, I found the edges bothersome, if that makes sense. But I bet (like with anything else in FG) that with some experimentation I could find settings that I like.

 

WIth everything maxed I get not less than 30 FPS in FG 2.10,, even in crouded autogen cities, or places with lots of trees.

 

With the regular shaders maxed & random buildings turned on, I definitely don't always get that!

 

I also know you have to dial the right freqs in your radios...

 

Yep - I really do like how there's a menu that you can bring up that shows all of the available frequencies for the area you're in. Helps to dial stuff in, for sure. It's just that I couldn't find a use for the ATC frequencies! It's pretty meaningless and I know it's not terribly realistic and full of flaws, but I really like flying VFR and interacting with ATC in MSFS.

You should also adjust rembrandt memory size alike the wiki, as it makes shadows look better. Also set antialiasing in fgrun alike the wiki.
