Maybe I can provide a comparison people are looking for. I just switched from a 9800x3d to the 9950x3d on my MSFS 2024 and 2020 rig that has many addons, peripherals, and background apps running while simming. I also use process lasso.
System:
4090 FE (no OC, rebar on, game mode, HAGS)
64gb DDR5 6000 ram at EXPO1
Strix x870-e
FSP 1000 watt titanium PSU
Lian-li gallahad 280mm AIO
Crucial gen5 NVME SSD
4k Asus QD-LED monitor
Test scenario software:
Fenix A320
Flightbeam SFO scenery
ASFS
FSrealistic
Say Intentions
GSX
Moza AB9 software
2x Streamdecks
Tobii eye tracker
Razer app engine
MSI afterburner
In this test I use process lasso to give MSFS2024 high priority on the 9800x3d and for the 9950x3d additionally assign the sim to CCD0 and all the other software to CCD1.
Test settings:
4k TAA
FG turned off (normally I keep it on, but wanted clean FPS numbers)
TLOD 200
OLOD 200
Ultra texture resolution
Mostly Ultra and max settings except a few high
Scenario is sitting on Runway 10R at SFO in the Fenix cockpit configured for t/o with heavy weather in the evening.
Results: (Avg fps, 1%low, 0.1%low)
9800x3d 42, 32, 24
9950x3d 52, 38, 29
So that’s a 23% improvement in avg fps and a decent improvement in lows in this particular scenario with the 9950x3d. Benchmarks by the major publications on MSFS don’t give much useful insight into real world usage for people like me who run a lot of addons and background software.
I mainly use MSFS2020 with even more addons and plan to use PL for this use. I did recently get some instability with freezes and crashes in both sims with a lot of stuttering in 2024. I think that confining 2024 to CCD0 with PL may not be the best choice as turning that off and letting windows schedule the sim with the latest chipset drivers from AMD and balanced power mode has led to fewer crashes. I also think my recently added Streamdeck setup may have caused some instability in both sims, not a 100% sure yet. I’ve disconnected for now and will attempt to re-install all the software.
Hopefully this is helpful to some of you. Anybody else have experience with Process Lasso for MSFS with this latest CPU? Any tips?
