After finally making the permanent switch to MSFS2024 I am experiencing servere FPS degradations on my flights, all of them, no matter the time.
I’ve done 3 flights in total and it is extremely apparent that I am getting some degradations over time here. I’ve done LHR-JFK, JFK-LHR, and LGW-BFS, and for an idea on how bad it is I play on 1080p meduim with these specs:
-Ryzen 7 9800X3D
-AMD RX7900XT
-TForce Delta DDR5 RAM Kit (6000MHz, CL30)
-Gigabye Aorus Elite B650 AX V2
-Crutial P310 1TB NVME
(rest is not relevant)
On the LHR-JFK flight the degradation was not as noticable as I was not paying much attention, although on the way back when comming into LHR I expected it to be up around in the 50s or even 60s as all of my settings are optimized extremely well comming from an ancient proccessor and a GTX1650. Once I landed I parked up and took note of my FPS (was around 33, stable with no frame generation), I then closed the sim down and fired it straight back up into the exact same situation, exactly the same. It was around 75, stable, without the frame generation.
After that flight I downloaded Intelegent Standby List Cleaner (ISLC) which was reccomened by a fellow YouTuber which basically clears out your DRAM. Not completely sure how it works, but they said that it was basically a great app for long haul flights. Then after doing LGW-BFS just today i checked it again. It was 55 FPS stable at the destination beforehand, and then it was well above 78 when I reloaded the sim.
Now I am used to having slightly lower FPS after a long flight, as I would expect it mabye to drop a few frames. But this guys, is like a complete dive down in FPS compared to what I would expect. I’m currently on SU2 (stable) and I am wondering if anyone else is having this issue at all in both SU2 and 3, or if SU3 Beta is the solution.
Just like to put out the things I’ve tried as I dont want to waste anyones time:
-VRAM is not an issue. I have got plenty of space.
-Thermal throttling is not an issue. Temps are extremely stable and not even close to overheating.
Also would like to say in case it comes down to it. My PC is a custom build, I built it myself and I’ve had it for about a month, but not been able to actually use it as I’ve had issues with the PSU clicking. (heads up don’t by Corsair’s RMe series, it’s basically a 50/50)
Thank you for your post! Your topic has been moved to a sub-category of the User Support Hub

If you would like other users to help you with an issue you are experiencing in the sim, consider these User Support Hub categories for your future post:
Hello, a lot of info above. For clarity, what aircraft model(s) are you flying to these large airports (any of them 3rd party/which ones) and what FPS counts as severely degraded? Just wondering. Nice rig!
I am running all the top of the line aircraft. Although I only am using currently the Fenix Airbus A320 Family and Inibuilds A350.
As for airports I have most of them from FS.to as well as some purchases I’ve made on various platforms including MSFS Marketplace and Inimanager.
I wouldn’t consider an FPS as ‘degrading’ but more the difference. I am alright with mabye 5, 10, FPS loss after a long 10 hour flight but just after an hour and a half uptime flight dropping almost 50 FPS is not on for me. I like good frames as it is the one thing that makes my sim feel amazing for me. I know that people aim extremely high on the settings and thats not for me.
Anyway my friend I just hope to get this fixed, I will continue to fly with it, but there will come a point in time, hopefully not, where I will once again have to switch back over to the old simulator, where I do not like the lighting and shadows could not be worse.
737max, every flight, - as the flight proceeds, the FPS starts reducing, can usually tell because it gets a bit sluggish in cruise (least demanding phase), on final to land is rather messy and sluggish to say the least.
I checked today, got on the stand at destination, FPS, was barely touching 25 (average), ended the flight, restarted sim and loaded directly back up at the destination gate in the same conditions, back to solid 60 (v-sync on).
FPS and performance is absolutely degrading with time, i have a 3090.
No thermal throttle or VRAM issue on my end either,
I used 2020’s 788 the other day, cannot say for certain if i had the issue in that aircraft, supposed i’d have to test it out again to confirm for sure, but defo 738
Hiya mate thanks for the reply, I’ve got the fix, for me at least, here’s what I’ve done:
Alright so once again Windows and it’s idiotic power saving settings have striked again, I saw this video on YT, which I can’t find in my history because I was watching it on my laptop which was new and so on.
Anyway it said to do the following and here’s what helped me:
Go to search, edit power plan
Advanced power settings
Look for processor power management
Set the minimum processor state to 100%
Now hopefully you aren’t going to listen to some rando on MSFS forums but I’m gonna give my word to you that I’ve done around 3 flights with this setting on, 2 of them being well over 7 hours and another being short haul, and it’s been competely fine for me. On the arrival into LHR I had some really, really bad FPS issues but this thing blasts it all the way up to what it should be.
The video I watched had 2 different methods but the other involved going into the registry, which I am not putting the potentia fate of my PC or whatnot in the hands of some guy on YT.
Just gonna put out there that this may not be the fix. I’ve went into my BIOS and fiddled around with some of the CPU enhancement settings which where already enabled anyway. Only thing I can think of is my silly ahh turning on XMP instead of EXPO.
Anyway mate I hope this helped you, it’s been all aircraft for me, and remember, expect your FPS to drop slightly when parked up and all. It’s been running for hours and needs a rest xD.
Interesting, thank you, i’d be surprised if it fixes it for me, given i had no issues with another aircraft, but nonetheless, i will go ahead and give it try
Thanks for coming back with a detailed answer, i will update once i have tested it out.
Glad your problem has gone away, will see you in the next post with a new problem
Hey there mate, I may be on to something here. I’ve got the problem again with SU3 out.
I’ve turned resizable bar off and I think it is helping. So far I’ve ran 2 identical flights about an hour long and it seems to be that I end up with more fps after with rebar off. The only thing is if you restart the sim you end up with more fps with rebar on.
So I think the conclusion from this is that rebar is better in the short term but not as good in the long. Keep in mind the fps differences were around 10, but this was with a 1 hour flight, meaning the degradation hasn’t settled in fully and was recorded before it got marginally worse.
I’ve got a similar issue since SU3. I’m flying in VR with a 5080 and 5800x3d with 64gb Ram. I’ve got my settings very well dialed in.
VRAM & temps are a non issue.
On departure I’ll get a perfectly locked 45 fps in the headset in a heavy PG area like LA for instance. Fly an hour east over to the Phoenix area and once the PG starts loading in, I’m down to 35 fps.
It’s definitely not unusable or anything like that….just annoying.
I have absolutely no idea why it happens. It certainly did not used to. I’ve been tearing my hair out the past week trying to figure out what could be my issue. I’ve come to the conclusion that I don’t actually have an issue, and it’s a sim issue.
I use process lasso (from bitsum) , it helps a lot with giving msfs 2024 exe high resource priority and locking it in.. matter of fact I’ve been using it since since back during FSX, P3D, and 2020…
I got similar specs on my rig, and after SU3 it worsened the situation for me.
@Flint2346 ‘s solution unfortunately does not work for me. My flying consists of mid to long to ULR in flight and it usually gets really really bad after 8+ hours.
