But FSHud already injects and controls AIG aircraft. I have had this set up for a long time and it works ok. What does the new version do better/different than the old version?

Thanks The window title says: "Microsoft Flight Simulator 2024 - 1.6.34.0 with WideServer: waiting for clients"

Thanks, I can confirm it says 1.6.34.0

Many thanks for your quick reply. AutoFPS has worked fine for a long time, but with different versions I have suddenly gotten this particular error, seemingly for no reason. I cannot remember with which version this started. Yesterday and today have been particularly difficult and I cannot get the app working at all. No changes to hardware or software. Again many thanks if you would take a look at the log file, it is really annoying when it is not working! log as follows: 2026-02-11 10:48:52.062 [INF] ----------------------------------------------------------------------- 2026-02-11 10:48:52.205 [INF] [ App:InitLog ] MSFS_AutoFPS v0.4.6.4 started!

I am on MSFS2024/v0.4.6.4 and I keep getting the 'unable to attach MSFS" error. Had this error with several versions now (also 4.6.5). Have tried all suggestions in the error message (restart in menu, virus exclusion, admin) but to no avail. A reinstall of the app makes it work one time, but then it is back to the same error. Any ideas what could be causing this?

You could try to turn Light Shafts off

I am not getting this to work. With my triple screen setup I get a "realistic" FOV of 190° as per the calculator. This seems correct to me. If I divide 190 by 57.3 I get 3.31. FOV in Developer Mode Overlay goes from 1.29 (0% zoom) to 0.30 (100% zoom). It is not possible to reach 3.31 by zooming. What am I doing wrong here?

I think much will depend on your screen. If you increase atmosoheric depth (I think it is called), you will regain the blue sky colour

I agree. I tried the AirborneGeek preset, and it's looking good.

Thanks for the tip, however it makes no difference. You have either unlimited visibility, or you are fogged down.

I have just tried this for MSFS2024, and to my surprise, adding a tiny fraction of fog creates a thick fog layer. In MSFS2020 it was possible to add a tiny light fog layer in the distance, creating a, in my view, more realistic visibility range. This does, alas, not seem possible in MSFS2024. I am disappointed.

With Rex Atmos for MSFS2020 it is easy to add some haze to live weather. Just add a tiny fraction of "fog" and you get a much more realistic visibility range. It is also possible to increase humidity which "thickens" the atmosphere and reduces the visibility range. Looking a lot better with these tweaks I think. In addition you can "whiten" the clouds so they are not so gray and dark. This also increases daylight on the ground, which in my view is far too dark in MSFS2020. For me this program is a must with MSFS2020.

I deleted the config as you suggested, and all loaded just fine on next startup. Thanks for all your efforts!

It seems you have already figured out what the error was, but anyways, the two lines read as follows, on my system; WindowTop value = -32000 WindowLeft value = -32000 So I am guessing the window is far out there somewhere

Same here
