I noticed that if you try to change msfs 2024 gfx settings while running AutoFPS, you'll get a message that basically doesn't want you to do that, which makes sense.

Lately, I've been playing with FCR and like to run FSR3, instead of DLSS when watching replays. Less ghosting. I've been switching this on the fly with no message coming from AutoFPS. Does this cause an issue with AutoFPS?

Thanks

 Sir thank you for autofps 

Absolutely love it.

Question thou regarding using frame gen as I just started using it For 2020 how would i go about settings in auto fps.

 

Shall i use cap sensitivity or tolerance?

Man 3x fg?

Fps target at 48?

144hz monitor freesync 

 

Vsync is on in Nvidia control panel.

Thanks 

Mike

AutoFPS only makes a fuss if you change a setting it is currently managing, or could potentially manage if you changed AutoFPS settings mid-flight. FG type is not one of them, hence no warning and this is not an issue.

Normally, I don't give out individual settings advice, but you've been around here for a long time so I will make an exception this time.

FPS Cap if you have capped FPS somewhere else and your system is running mostly at that FPS cap, otherwise FPS Sensitivity (don't worry about using Tolerance mode unless Sensitivity mode is a stutter fest)

Quote

Man 3x fg?

If you have externally set FG to 3X and it is not otherwise auto detecable by AutoFPS, then yes.

Quote

Fps target at 48?

If 48 FPS is your target after 3X FG is factored in, then your raw FPS is 24 which is pretty low to get a good FG experience. If, on the other hand, 48 FPS is your base FPS, which is good for FG, then set your target FPS to 3X times that ie. 144.

144hz monitor freesync 

Vsync is on in Nvidia control panel.

 

If your target FPS is 144 from the point above, then 144 is all you will get so you may as well use FPS Cap mode in that case.

Understood.

I forgot to mention that this is in the anti-aliasing area and it is being changed in sim, not in AutoFPS. Although, it still doesn't seem to be affecting anything, changing in mid flight.

Thanks again.

Yes, anything AA, FG , and Vsync in MSFS settings does not cause a red card because the app may monitor them but does not actually control them.

All you really need to know is that if you are not being pinged, then that is an acceptable setting to change.

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?

I won't be in front of my Dev PC for about 8 hours, so I can't really speculate for sure what the issue is but it is usually a permissions issue with AutoFPS being able to see that MSFS is running but not being able to get access to where it lives in memory. 

In the interim, can you message me the contents (copy and paste - you can't attach files here) of your latest log file, located in %appdata%/MSFS_AutoFPS/log, and I will see if it reveals any more. 

Also, has AutoFPS worked for you previously?  If so, what version did it stop working? Were there any other major changes on your system around that time, hardware or software?

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!

This line is of interest as it seems to be stumbling on the MSFS version number, which I have not seen before but gives me something to go on. I will be in contact via PM with what I find and possibly a special instrumented test version that can tell me a bit more about why the version number is not coming through.

IIRC, it pulls the MSFS version number from the MSFS Window title bar, so it would be helpful if you could tell me exactly what it says on your system. If in full screen mode, you need to hit ALT-ENTER to go to windowed mode to see the title. Once you have recorded the exact title, hit ALT-ENTER again to return to full screen. It should be "Microsoft Flight Simulator 2024 - 1.6.34.0".

With no "Microsoft Flight Simulator - " prefix? I need to know EXACTLY what it say, including whether those periods are actually commas instead.

In any case, as you are now on 0.4.6.5-test4, I will put out a version shortly that will log exactly what the entire MSFS window title says, so I can know what I am dealing with.

Ah, that's interesting. We'll take it to PMs from here as I want to keep this thread clean of detailed support. You'll hear from me very soon.
