And follow @Kanelbolle suggestions, most important remove the mods.

The mission F-16C_AFG_AI_CD.miz is causing CTD while loading, no crash logs or win events generated, it only need to be resaved from ME. (have yet to check other missions)

Yes! Yes! I can decide to buy from a e-shop with crappy policies, I can decide to use a smart-surveillance-phone, but since Windows is forced because of professional software requirements... It is, before 2001 it was unthinkable to give this impressive ammount of personal data to US corporations, but that's another argument.

You've moved from a 9700k to a 14700k, performance increase is expected since it's a faster CPU that runs better on W10+1. @Raven (Elysian Angel) : I know that is possible to install W10+1 with an offline account, for now, but it's not a straightforward procedure, this only shows how much MS is "unfair" (greedy). How hard is to release all the bloatware that's infesting W10/10+1 OS as a separated "Enjoy the CPU Extensive Datagrabbing Backdoors and Keyloggers Experience Pack"?

Performance: my previous tests revealed that W10+1 had a 5% performance loss compared to W10 (with some SW it was unusable because of intel thread director issues), maybe updating BIOS and chipset drivers now could put it on par with W10, maybe I could obtain a 2% performance gain, but this won't solve the latest DCS performance issues, look at the bugs section, plenty of W10+1 users reporting problems. Mandatory TPM: let's add another layer of vulnerabilities to the existing ones! If MS is so concerned about security why the multiple-times-leveraged useless BITS service is still around? https://thehackernews.com/2024/08/new-windows-backdoor-bitsloth-exploits.html Btw, TPM already had been used for the wrong purpose https://www.extremetech.com/gaming/326740-riot-will-use-windows-11s-tpm-2-0-requirement-to-ban-cheaters-from-valorant and had/have flaws https://www.bleepingcomputer.com/news/security/new-tpm-20-flaws-could-let-hackers-steal-cryptographic-keys/ , and don't get me started with mandatory online accounts and passkeys https://tinyapps.org/blog/passkeys-touted.html or all the (resources consuming) bloatware that MS is forcing to all OS users. Sorry, still no reasons to downgrade, Microsoft is disgusting.

Simapp? It could be, there were similar issues in the past with WW software interfering with other devices.

After removing the mods or renaming "Saved Games\DCS" folder did you perform a full repair? As last resort try with NV 566.36 drivers, the current ones are causing a lot of different issues.

Agree, and since 7 is getting worse with every update, but my 19045.3086 logs have no errors, only warnings (27, e1dexpress) because I disable the LAN before shutting down or for software installation.

Lately I often read the suggestion "Windows 10 will be EOL Oct 14th 2025. Upgrade to Windows 11", for a lot of valid reasons I have no intentions of enabling TPM and use a online account just to downgrade to W10+1, my question is: will DCS continue to run and receive updates on W10 machines in the following 2-3 years? Best regards.

No such issues with trackir 5 here, can you upload a dcs.log and a dxdiag.txt?

Check this: https://forum.dcs.world/topic/372899-realtek-alc1200-audio-causing-simulation-speed-fluctuation/#comment-5640225 NVIDIA Display Driver Version 57602.r575_92 Try with a clean install of 552.44 or 566.36 drivers (use DDU if you don't know what files to remove manually), also delete shaders in C:\Users\***\AppData\LocalLow\NVIDIA\PerDriverVersion\DXCache and C:\Users\***\Saved Games\DCS. Have you tried renaming the Saved Games\DCS folder? Maybe there are leftovers from current release causing performance issues.

Maybe this?

There's not much software developers can do when NVidia release borked drivers and faulty GPU's... Btw: 2025-05-02 07:55:21.013 WARNING EDCORE (Main): hypervisor is active 2025-05-02 07:55:21.013 WARNING EDCORE (Main): CPU HAS PARKED LOGICAL CORES (this can be source of stuttering and reduced performance especially on hybrid CPUs with P/E-cores) Disable core parking and Hyper-V and see if it still crashes.

Open "Through The Inferno (Syria - Damascus) v2.6.1p.miz" file with ME and under "define mission era here" change "modernr" in "modern".

Only if your logs are full of critical errors. Now I have 3 Win 10 Pro machines (+2 Linux), since 2003 with XP I never needed a reset/reinstall and performance benchmarks were the same as day 1 until the dismissal of the machines (2 W7 are still being used), the trick is to disable all useless processes/auto tasks/backdoors/spyware, don't let Win manage maintenance (do it manually) and make backups before updating drivers/software. Edit: forgot, disable disk indexing can prevent massive system slowdowns. Anyone noticed that it's slower starting/exiting but during the mission is more smooth and stable (except for the periodic spike)?

A dcs.log could be helpful... If you don't own a RTX 50 series card don't install any driver past 566.36, until they sort out the mess they've made, don't install NV App and if you use you're MB audio device or a sound card don't install NV HD Audio drivers. (Windows 10/11 sucks, don't ask me why...) Check your event viewer logs for errors.

This is not a GPU driver issue, I'm on 552.44, nor a chipset drivers, BIOS, OS issue, it's how DCS engine is handling the vast amount of data and computations needed by the sim.

Any news on this bug? dcs.log

Yesterday I've tested 2.9.13 and in SP loading time/memory usage was the same as current release, 2sec difference can be ignored, like was/is this suggestion: https://forum.dcs.world/topic/357590-4k-32bit-textures-on-all-modules/ , which could be the solution to all of our problems.

It takes time to release all the memory used by DCS, in TTI Sinai I've reached 8GB VRAM/60GB RAM (CTD, obviously).

Just came here to thank you for the updated pdf manual!

The question here is how to install an older version from scratch, the DCS_World_web.exe can be run with command lines?
