That's why you come here, or to the official ED DCS Discord server . Did any of those random people ask you for your DCS log file? Parked cores shows up as almost one of the first entries in the log file and would have been the first thing we'd told you to do (disable core parking). Would have saved you heaps of money and time.

Works on 4090 as well (I have a 4080super). Actually goes all the way back to versions of the 20xx series.

Yeah look in the log for the word “DLSS” or “preset” (sorry don’t have my log file in front of me). At least one of this lines found will include the word “preset” on that same line, and either be ‘C’ or ‘K’. If it’s ‘C’ then that is the DCS default and means it hasn’t picked up this change. I’ll edit this comment tomorrow with an actual example log line. There are a couple of other presets you can use as well, eg ‘F’ and ‘J’. Can experiment if you want to see if they look better for you. F is older and doesn’t use the new DLSS4.

You need to create it if it doesn't exist as per my instructions. Also make sure to use something like Notepad++ as Notepad can add a ".txt" extension to the end of the filename which you may not see if your Windows is hiding file extensions. You'll then wonder for ages why it isn't doing anything EDIT: Here's one I prepared earlier. autoexec.cfg

My mantra for the last 20 years has been "It's always the simple things that cause the most problems". It's true most of the time. Glad you got it sorted. Enjoy. Sing out if you need any help with anything. Our Discord is good for quick turnarounds with troubleshooting as well.

Make sure you've disabled hotplug devices in the DCS controls settings. Make sure you've disabled power management for your USB controllers in Windows Device Manager. Use powered USB hubs and spread the load.

Couple of options come to mind: 1. OpenXR Toolkit 2. Use Quad Views (install Quad-Views-Foveated and also Tally Mouse's Quad Views Companion app to configure it, and then enable Quad Views in DCS). Will reduce load on the GPU, but increase on the CPU (as it is creating 4 views instead of 2) although you have an AMD 5800x3D so this shouldn't be an issue, by creating higher resolution on the inner focused portion, and a lowered resolution on the outer region. The PSVR2 now has eye-tracking which makes Quad Views a definite option as if you use this then you'll only see the higher res image, the lower res will be out of view so you can make the lower res portion much larger. You could see some significant improvement with this. If you decide to try Quad Views then don't use OpenXR Toolkit at the same time.

Just for curiosity sake in case this comes up for others, why did you have the "force_cross_eye_recovery_tool" entry in there in the first place? What does this do?

Single-threaded no longer exists anymore. Both the executables in bin and bin-mt are multithreaded and bin-mt will be removed in the future. It's all OpenXR these days.

I've had a look at your log and two things jump out. Start with #2 re: the mission editor. 1. You have a bunch of mods in there and some of them have errors. Remove them and try again. Error '=' expected near '|' Line 1 Script ./MissionEditor/modules/me_map_window.lua Error attempt to call global 'BrowningM2' (a nil value) Line 289 Script ./CoreMods/WWII Units/A-20G/A-20G.lua Error attempt to call global 'BrowningM2' (a nil value) Line 239 Script ./CoreMods/WWII Units/P-51D/P-51D.lua 2. You have the below error in a MissionEditor file. Can you try renaming Saved Games\DCS.openbeta\MissionEditor to MissionEditor.old and trying again. 2025-10-07 03:45:32.999 ALERT Dispatcher (Main): Error starting Game GUI: error loading module 'me_map_window' from file './MissionEditor/modules/me_map_window.lua': [string "./MissionEditor/modules/me_map_window.lua"]:1: '=' expected near '|' I went and ran your log through the log analyzer which has also highlighted the corrupted mission editor file. Config File Corruption Delete or rename Saved Games\DCS.openbeta\MissionEditor and try again. Failing that completely rename Saved Games\DCS.openbeta to DCS.openbeta_old (rename not delete so you can copy back your keybindings from Config\Input and stuff from Missions) Running a repair of the game does not touch your Saved Games\DCS.openbeta folder, this is why you may be seeing issues due to corrupted files in there even after running a repar.

Sounds like an unrelated problem so raise your own post. Attach your DCS log file after replicating the crash, might be something simple.

If it's a brand new install then make sure that core parking is disabled (ParkControl software can be used for this to disable for all the power management profiles) if you haven't already. Same thing applies to things like turning off power management for your root usb controllers in Device Manager.

In this log, and one of your earlier ones there is an ANTIFREEZE event along with a plug event for a Samsung TV as the last entries in the log before it stops: 2025-10-05 21:41:04.147 INFO APP (Main): Device plugged: [SWD] Samsung Q60AA 43 TV 2025-10-05 21:42:45.526 WARNING LOG (17080): 2 duplicate message(s) skipped. 2025-10-05 21:42:45.526 WARNING WORLD (Main): ModelTimeQuantizer: ANTIFREEZE ENABLED What is this device and how is it connected to your PC? Regarding the mission and changing the plane. Is this replicatable vs. coincidence? What happens if you do the reverse, take the MiG29A mission and replace it with the Mirage? Can you replicate this issue with other non-MiG missions and replacing the plane with the MiG? Just wanting to confirm whether or not it is an issue with that mission that is somehow triggering it.

It's telling you it's time to play DCS
