While this could be done, I don't think it will achieve the desired effect as turning down some settings like those you suggested will just allow others to have a greater share of GPU time and hence your GPU will still be running at full load.

GPUs are designed to run continuously at full load, so this shouldn't really be an issue unless the temps and/or noise are bothering you, which seems to be the case with temps at least. The first thing I would consider is are you worrying unnecessarily, since the nVidia spec for the 3080 Ti shows a max GPU temp of 93C and yours is a full 10C under that. Why not just let it run at a higher temp, still below the maximum of course?

The next thing I'd be looking at is whether your GPU cooling is being obstructed in some way eg. dust build up or inadequate case airflow. You can also try undervolting your GPU in MSI Afterburner, which often yields lower temps/noise/power for the same performance, but only if you are comfortable doing this. There are plenty of youtube guides out there on how to achieve undervolting with MSI afterburner and advice on what is a reasonable undervolt that could be achieved.

If GPU cooling and undervolting has been sorted and you still have a higher GPU temp than you want, the simplest and cleanest solution is to set a lower temp limit in MSI Afterburner. By cleanest I mean that this will spread the GPU performance reduction equally across all current GPU-related MSFS settings. This is opposed to the app trying to guess which settings are contributing most to the load and then, as mentioned earlier, after reducing them just having other settings take up the spare GPU capacity and not resolving your issue.

 

Great info and points all around, thank you.  The reason I bring this up is I can get stuttering during thermal throttling.  I do take my case apart and clean the dust a couple times a year and just did this a few weeks ago.  I think undervolting may be the solution as I don't think the stock FE fan can handle constant 95% plus GPU load for extended periods of time like we need in flight sim.  At least not confined in my small home office in Florida where ambient temps can creep up there.

Is this available to download-I only fly in VR so am keen to test that functionality

FYI, the latest test version 0.4.4.8-test9, available here, now supports multi-setting reduction in VR, albeit only changeable for VR on the app's UI when you are in VR.

Hi there,

So I started msfs24 again after a few months and just updated Autofps to v0.4.4.7 with default settings and I get unflyable conditions:

9 FPS with TLOD 115 and OLOD 120 with a target at 40fps with my poor RTX2060

I also tried Auto target and expert mode but no joy.

I was expecting something around 40 fps with TLOD at 80 or 70

Did I miss something?

Thanks

That is indeed very low. What CPU and RAM do you have? Also, what graphics settings do you use? In particular, display resolution and TAA vs DLSS. 

Performance is of course also highly dependant on type of aircraft, airport and photogrammetry on vs off.

As requested, this functionality is now in 0.4.4.8-test7, available here. Let me know if this is what you wanted.

works like a charm, thank you very much 🙂

I gave this a test run and it works really well in VR for me!

If your RTX2060 only has 6BG VRAM then your PC is likely just above the minimum spec to run MSFS 2024.

As such, you should be running MSFS at medium, and even low settings. A TLOD of 115, which is around what the high preset gives you, is probably too much for your system and your VRAM is overflowing, causing such low performance. You should really be using a TLOD of around 25-50 with your GPU spec.

What performance do you get with using the same settings AutoFPS is setting in MSFS without AutoFPS running? If similar then your issue is the settings you have chosen. If significantly different, message me your log file contents and we'll take it from there.

I coded this up today and there is good and bad news. 

The good news is that I was successful in being able to determine the sim rate, albeit indirectly. I now have the app show this at the start of the status line where it will show the sim rate anywhere between 0.125X and 16X. This may be useful for some users wanting to know what their current sim rate is set to.

The bad news is that using this detected sim rate to calculate an effective ground speed and have the app auto reduce TLOD when it gets above a certain speed yielded a negligible reduction in CPU workload and temperature on my system. eg. with a trigger speed of 500 kts and flying at 500 kts, when I increased to 4X sim rate for an effective ground speed of 2000 kts, the app reduced my TLOD Max down from 400 to 100 and the CPU workload and temperature remained pretty much the same.

As such, I don't think this is worth pursuing any further. As I mentioned in my initial reply, the way I have averted such high CPU temps when flying supersonic or subsonic but with time accel is to simply change the Windows power profile to power saver using PowerPlanSwitcher on the taskbar and that cools and quietens everything down for me, then just change it back up to balanced or high power when you slow down.

Edit: The testing I did was with MSFS 2020, since you mentioned PMDG so I assumed that was the sim you were interested in having this feature. I just tried it in MSFS 2024 and while I got the same negligible difference in CPU temp and load, my CPU temp was running at nearly 30C lower than it was in MSFS 2020 at 4X sim rate in an airliner! MSFS 2024 seems much better at managing CPU load. If only there were a few decent PMDG offerings working in it (oh and VR too, which is also pretty bad in 2024)!

Hi, need to get back to that topic. I tried the Power Saving Mode to get my CPU Temps under Control, sadly that doesn't work for me the CPU is still getting to hot when using X4 Time Accelleration.

What did work for me is using TLOD setting of 20 or 10 and i get a stable 60fps and no freezes. So is it still possible for you to implement a setting to set TLOD to a very low setting when using sim Rate increase ? For me its getting a better and more stable  Sim. Currently also trying to use the VFR tab for that and switching Manual to it when i am using Sim Rate increase of my PMDG. So i guess for me it would be also fine to just get another Setting like IFR/VFR 😄

Power saving mode should significantly reduce your CPU temperature if it is turning turbo off. If not, it suggests to me that either turbo mode is not coming off or your system has inadequate/blocked CPU cooling that you need to address.

For the former, I suggest you select power saver power plan, go into window settings and search for edit plan settings, select change advanced settings then make sure that under power management both min and max processor states are 0% like so:

To verify your CPU is not running at turbo speed when configured this way, open task manager to the performance tab and make sure your CPU speed is showing lower than the base speed eg.

 

If, after all this, your system was running at non turbo speed and is still overheating at high CPU loads then you have a cooling problem that you need to fix. 

FYI, my CPU will not get over 45 C at 100% CPU load in power saver but in all other power plans it can get as high as 90C if I leave it long enough as I only have a moderate cooling solution myself.

 

 

This thread has got so long, I'm losing track but I have the latest App version and have set the target FPS to 53 whilst my top rate is set at 60 FPS in Nvidia control panel and my minimum is set at 100 TLOD and max TLOD at 200 in the app.

Reallly I only need it to drop to 100 TLOD at a few very heavy airports and would prefer it not to drop to that level if it doesn't need to.  Is there a way to set it so that this happens (I think that was possible in earlier versions)?

Enabling TLOD Min + should do what you want:

 

See the readme for more info on how it works.

Thanks Reset XPDR.  I've just applied those two ticks and will see how it goes.  It looks like your new test version has a few more interesting features.

The new auto setting reduction in marginal conditions feature is coming along nicely. I'm really now just waiting for SU2 beta to be released to make sure it stays compatible.

So far with test 13 its working for my GA. Though I am getting some odd "sound" glitches/crackling with some stutters. Can't locate it buts happening today. And about 2 weeks ago. Not helpful.

Anyone else getting a crackle of sound with a stutter?

I’m getting those sound «stutters» too occasionally, but I have given up on trying to troubleshoot it.
