Please only participate if you are running the 7950x3d or 7900x3d, thanks. If you are using the 7950x3d/7900x3d with MSFS 2024, please share your experience. I am especially interested into information confirming the real usage of cores/threads. If you are looking at cpu usage within taskmanager (…

[image] BegottenPoet228: think Process Lasso is a must with the 7950X3D (and probably any other mulit-chiplet design with Vcache on one chiplet, and non-Vcache on the other. Yep. The 7950X3D has 2 cpu chips (CCD). Both with 32MB L3 cache, but one has an extra 64MB cache on top to make up 96M…

I appreciate seeing this discussion here as I’ve had multiple CTDs in FS2024 with Hyper-Threading (HT) turned On on my Intel i9-14900K. I’ve had zero CTDs with HT turned Off. Ultimately, however, I was able to get FS2024 to run more smoothly with fewer CTDs with HT On and the Windows Power Plan set …

[image] PilotJedi668: Scientifically we need to compare X3D cpus to standard cpus with 64MB and 128MB cache. I think that’s a fair point, when comparing AMD to AMD. A 9950X has 1.28MB L1, 16MB L2, and 64MB L3 (total 81.28MB.) AFAIK they don’t make a ‘non-X3D’ with more than that.

[image] Wdseith: Intel chips already have thread-scheduling built into Win11. I’ve never had an issue with the way Intel’s thread scheduler optimizes the cores and therefore see no need to add yet another background process to the mix, especially one that may conflict with Intel’s thread schedul…

@TenPatrol , you and I have already had an exchange on this subject on a separate thread that I posted here. As you know from that discussion, I have already speculated that my issue with HT On may well be related to the known bug posted by the FS2024 team. While having HT Off resolves the issue comp…

[image] TenPatrol: With both HT and the E-cores enabled your Intel i9-14900K processor will have 32 threads. This means there is a high probability that the CTD you’re experiencing is caused by a known bug in MSFS 2024. Crashing issues when using CPU with more than 32 cores If you are using a…

[image] Vibstronium: That quite clearly says that 32 logical processors is expected to work, and that having more than 32 logical processors is a problem. Here’s a corrected version :wink: If you are using a CPU with 32 or more cores, the sim will crash. We are aware of this issue, and it i…

That’s not what the linked FAQ says. It quite clearly indicates that the recommended workaround is to set the maximum to 32.

7950x3d - does 2024 use more then the 8 3D cores?

Here’s a corrected version

If you are using a CPU with 32 or more cores, the sim will crash. We are aware of this issue, and it is being investigated.
