Most of my cores are at zero and at one point, there were no cores above 5% and that was just one of them, a couple were at 1-2%. No cores are ever anywhere near even 50% usage. This was checked in CPU-Z and the task manager (I think). A separate FPS counter does indeed report roughly twice the in-game FPS with FG on, I know that I am lucky to finally be able to afford a nice system after a decade of my old 4690k and don’t want to seem ungrateful, but it’s just so frustrating that on the ground at Launceston I am 40fps down on what are essentially the same settings. The only thing that has changed is a sim update (SU15). I feel like I am obsessing over this, but I guess I just need to know my CPU isn’t on the fritz. I do appreciate your taking the time to reply to this, though. 🙂

I have only watched a couple of YouTube videos about the instability issues, but thought that it didn't affect me as Scan said that they has tested the CPU and it was fine. I am out of the returns window, I believe. To be fair to Scan, they have tried to diagnose the issue, but as far as they are concerned, the system is running well. Thank you for your suggestion, though.

My PC achieved a good score in TimeSpy and Scan remotely stressed the CPU and they were happy with the results. I guess I just can’t figure out where almost half the frames have gone. I wondered if some setting in my monitor was the culprit, but it is set at 165mhz, so I don’t think that’s the issue. I do have a month free on Game Pass so maybe I should download another game and try that. Thanks for the idea. 🙂

Thank you. Should have introduced myself a long time ago! 🙂

Hey everyone, I had been simming in MSFS on an old i5 4690k and a GTX 1070, locked at 30fps with a 1080p screen. My settings were mostly medium to high. I purchased a pre-built 3XS system from Scan which has these specs: i9 14900KF MSI slim RTX 4080 Super 64Gb of RAM ASUS Prime Z970-A motherboard Corsair RM1000X power supply 2TB M.2 SSD Liquid cooling with 6x Noctua fans Alienware AW3423DFW monitor I installed MSFS and when I first ran it, all the setting were already set at ultra and the framerates in the A2A Comanche at my test airfield, Launceston, were between 82-84fps. I ran the sim with FG on. There frames were the same at Auckland, give or take a few FPS. After about 10 days the frames suddenly fell to around 64 fps, all the time. I ran Memtest and the RAM failed with 233 errors. The system was sent back to Scan and new RAM installed. I reinstalled MSFS and was back at 80fps, but after four days, the frames fell to around 64fps again. I also had an issue where the FPS was oscillating between 56-64fps every 2 seconds or so, but solved that by uninstalling FSUIPC. After SU15, the frames have steadily decreased until now I get around 50fps on the ground at Launceston and about 46fps around New York with the same settings. I can't for the life of me work out what is going on. The FPS display says I am main thread limited my CPU usage sometimes shows only 1 or 2% in CPU-Z. My temps are low throughout. I can accept if these are acceptable framerates for my system, but I have seen people run 4K monitors with better frames than this, plus, I had over 80FPS consistently for 10 days when I first received the PC.. I have asked on the MSFS forums, but no joy there. I would appreciate anybody's help with this. If anybody needs anymore information on my setup to help diagnose the problem, please let me know! Thanks, Mat

Okay thanks. I will ask again on another forum to see if anybody has any suggestions. Thank you!

Hi Guys, My name is Mat and I have been a long time lurker on these forums. Thought it was time to say hello. 🙂 I currently am using MSFS and have some questions, so will be picking people's brains soon!
