Hi,
My computer has the following specifications: 7900X3D, 6800XT, 16x2 32GB 6000CL30 RAM. I am running 3440x1440. MSFS is installed on a 1 Terabyte NVMe SSD with 617 gigabytes free.
I am experiencing major performance issues. Some context here:
I was running Windows 11 and was having great performance. I was getting about 66-68 FPS with the PMDG 738 at ini OMDB. I had surrounding iniBuilds and Orbx Dubai landmarks scenery installed as well. This was after I upgraded my RAM and got something of high quality. You can see me talk about about my performance here.. This was running the Ultra preset, TLOD OLOD 200, Motion Blur set to off. Some slight stutters whilst panning camera around but nothing noticeable. I was always GPU limited and MSFS would never switch to being limited by mainthread.
My installed addons whilst getting frame rates in the high 60s (note, I had some other random stuff in my community folder that doesn’t show here, like the 737 and liveries, navigraph stuff, volanta plugin):
I had to reinstall windows and wiped all my drives completely due to memory leak issues. I had no clue what was causing this, which is why I took this approach. This fixed my memory leak issues, but caused something else for MSFS. Note that MSFS was also completely reinstalled. I do not have any World/City Updates
I am now averaging 53 FPS at ini OMDB with the same surrounding landmark scenery with the PMDG 738. Ultra preset with TLOD OLOD 200, trees and buildings set to High, texture resolution set to High, Motion Blur off.
Loaded sceneries with performance loss (and 737 loaded, no liveries, nothing else):
This might seem like an insignificant performance loss, but this actually turns to insane performance issues when I try to run a full flight.
In an actual flight (with the same settings I mentioned earlier with the reduced performance BUT my TLOD is set to 50 and OLOD is set to 100 – TLOD switches to 200 at 50FT AGL when I take off), I am now getting 35-30 fps at ini OMDB’s Terminal 2 at the stand (which is Dubai’s budget terminal and is no where as intensive/grand as the main terminal 1 and 3 with no interiors), only the orbx dubai landmark (i did not load the inibuilds landmark pack due to frame rate issues) and the freeware OOMS scenery on fsto. There are significant stutters even slightly panning the camera around. I have tried running DDU in safe mode and clearing my dx shader cache in safe mode as well (clearing shader cache doesn’t do much for me with my AMD GPU but I did it nonetheless). Taxiing at OMDB gives me fps averaging 25 fps and taking off gives me fps in the 10-15fps range (this is because TLOD is switching to 200). Even at cruising altitude I am averaging 45-50 FPS which is incredibly low compared to what i was getting before, which was in the mid 70s,
To reiterate, this was never an issue before I reinstalled windows. I don’t know what changed after I reinstalled windows. Now I am running my graphic settings significantly lower than what it was set at previously, still getting worse fps with insane stutters, and I have no idea how to fix this.
I have run memtest86 and my memory is fine. My CPU is watercooled with an AIO and after monitoring HWINFO, it is not thermal throttling. I have also checked the life of my NVMe drive with crystaldiskmark and got a 99% health rating. I am at a loss here and I don’t know what to do.
I have reinstalled my GPU and Chipset drivers after using DDU to delete my graphics drivers in safe mode, cleared my DX cache. All drivers up-to-date. I genuinely don’t know what the problem is anymore. I should be getting so much better performance in flights than I am getting right now, but I don’t.
All your help is appreciated, thank you in advance.
