My 10900K system runs the sim very smooth in DX12 with no stuttering. I do experience moderate terrain pop-in and mountain morphing from time to time.
My 13900K system is very stuttery in DX12. In DX11 the stutters improve slightly, however I experience periodic long freezes of a few seconds. The rendering of terrain is an improvement with less pop-in and morphing.
Im baffled as to why the 10900K system is smoother than the 13900K system. I have tried many different settings combinations, clean installs of graphic driver versions, but I canāt seem to rid the stutters on the new system.
Hello,
We ask that people not use General Discussion for help, advice, or troubleshooting. Please use the green Community Support subcategories. I have moved your post to Community Support > Tech Support.
if you can not find out, with all the informations you have, while sitting directly in front of your PC, while you checked āmany thingsā, etcā¦ how should we imageing with the given informations what the problem of your new system is ?
Recommendation: let run some performance test tools and compare the results and ensure in that way, that there is not a generall problem with your new pc ( hardware, e.g temps, or a setting ).
Check the mainboard drivers and all that stuff, I know as own experiance that some z790 are electro-waste , nothing else. Also have an eye on the 990 firmware, there was a horrible bug. And I cant never understand why users disable HT. Otherwise million possible reasonsā¦
Hi, I experienced exactly what you describe, too. Especially when flying in VR. It took me months to find out, that lowering MSFS to low in the process priority (task manager) gets rid of the stuttering issues after the hardware upgrade.
Please donāt ask why setting the process priority to low helps, but in my case it solved all of my problems.
Iām using Windows 11, latest Nvidia drivers (overlay disabled), HAGS off, gamemode in W11 off, ultra settings in MSFS, no FPS limit in NVCP or in game.
Hope it works for you, too!
In my case the priority was reset to high automatically for some reason while MSFS was running. Thatās why I now use process lasso.
Classic symptoms indicating your overclocked 4090 is too powerful for your cpu (or any cpu) at 4k. Things that may help -
Increasing resolution/ renderscale (if using DLSS then use DLAA with it)
Maximising gpu intensive settings
Decreasing cpu intensive settings (T-LOD, traffic)
Multimonitor
Hi end VR
but it has no disadvantages, so it can be stay enabled and so the virt. cores are there if they are needed. Performance lost because of the little overhead of HT managment is long ago. More complex is in meanwhile the P- vs E-core management. I have no issue with my system with same CPU - more in contrast of that the sim runs much smoother compared to my old CPU ( an i7-8700K ). Therefore the recommendation for let run a perf-test/stress-tool.
I have a very similar setup and itās silky smooth, so Iād guess it might be due to āover-tweaking.ā
Turn on Hyperthreading.
Turn off VSync
Turn off the frame rate limiter ā youāre on a 4090 that can maintain over 100 fps with frame doubling at 4K with details cranked, donāt limit your FR. Wonder if that might be affecting your refreshes?
I spent last night and my day off today doing a clean Win 11 install, updating drivers, ME and BIOS to 0904. I just finished a clean install of MSFS and so far, so good. Iām getting very smooth performance in DX12 with no stutters or pop-in. I must have screwed something up with my previous build that was translating to the sim.
Iāll update after Iāve had an opportunity to put in some more time. Thank you all for your advice.
Are you sure the DDR5 is REALLY running at 6400? AFAIK, no mainboards are currently capable of running 4 sticks (64 gb) of DDR5 at the XMP speeds. (or really anything above the base memory speed)
