So i recently updated to windows 11 and the issue went away for several weeks but it just came back, I had my game freeze my whole system in the mission editor again today. This is with track IR running however, I will try replicate the issue without trackIR but in the past I have been able to get it to freeze without running trackIR I just didn't save the logs at that time as I was trying all sorts of potential fixes, and pulling my hair out. I will try and post it again if it happens without trackIR just to rule it out. DxDiag.txt dcs.log

2025-04-17 21:27:04.445 INFO DXGUI_WIN_ADAPTER (Main): ChangeDisplaySettings failed! Result is -1 This seems to be the culprit.

Game is still freezing as of update 2.9.15.9408 logs attached. Can someone from ED please weigh in on this issue Multiple threads have been started, across both Russian and English language forums, several people on discord have encountered this same issue. I have been through the ENTIRE Crash trouble shooting guide, with no success. This issue is completely sapping my enjoyment of the game. dcs.log

Me too

I'm experiencing full PC freeze when DCS starts. A solution that has been working for me is to, before opening the game, delete metashaders2 and FXO files in saved games folder, perform a short repair of DCS and finally perform a cleanup from the launcher, and then DCS runs great for me. I Its only a workaround though, the last major update (the one that introduced save functionality) clearly borked something, that or its some kind of driver issue or both, the new NVIDIA driver has lots of issues with multiple games. My latest log is attached which is from a session where the game froze shortly after starting, shows no errors. The log analyzer in DCS discord recommends rolling back GPU drivers. dcs.log

No effect on the freeze for me, with or without park control. The logs also don't show any cores being parked. It freezes with and without trackir for me as well.

Very interesting, so I used to use the task manager to uncheck and recheck affinity for all cores in the DCS process, and that would instantly net me 20 - 30 FPS. So you might be on to something. This was before when I could get passed the main menu though. So I will give this a try however the problem I see is that, once the freeze happens my entire computer locks up, all im able to do is restart. But I might be able to do this before the game completly loads and freezes.

First thing I tried. Before renaming my entire saved games folder. No effect in both cases.

So this solution is now working for me as well, however I must also restart my computer between sessions, then I can do a repair and cleanup, and finally it will run. This is problematic however since I will have to rebuild shaders literally every game session, and DCS lags quite a bit during that process. Seems like a corrupted file path is created each time the game is started, which then causes it to hang the next time it is run without doing a cleanup and repair.

No effect, this isn't a stutter or FPS problem btw. I get around 80 FPS in game, when DCS is running like it had been prior to 2.9.14.8222. Instead this a full system freeze. My whole computer stops responding, Mouse keyboard, screen, controllers everything. I have to do a hard restart of my PC when it happens, and it happens now everytime I start the game, and only with DCS. Several other resource intensive programs on my PC have no issues. So I don't think its a hardware problem either, otherwise it would be happening with other major programs too.

Neither of these worked to fix the freeze on startup. Latest log attached. dcs.log

Interesting does it ever freeze mid mission for you? I was able to get past the main menu by doing a slow repair and check for excess files. Only to have it freeze again mid mission and then subsequent restarts result in it freezing on startup again. I'll try that, but many of my freeze logs have no hot plug issues so I'm not sure that's it's related. Also I have hot plug disabled in the controls section. So if it's still on then that is a separate bug.

Just updated BIOS did not fix the issue for me. DCS is not being run as admin. Latest log attached. The game worked for a second and i was able to hit the settings button and load the settings menu before it completely locked up on me. Haven't had any major performance/Crash issues in DCS for several years now. Definitely something to do with the last major update. dcs.log

Ive had this same issue since the second to last update as well. DCS log analyzer can't find any showstoppers. Driving me up the wall. dcs.log

As I stated in my first post I'm not running it in admin mode and I checked both places where that could be on. Core parking has been disabled on my PC for a while now. It's definitely a new bug that has been introduced, for some background I haven't had a straight up crash with DCS in years, and now I can't get past the main menu without it completely locking up. I meet all the system requirements for high graphics settings. I typically have 60 - 80 FPS. So I definitely think something got borked by the last major patch.

I'm having Major Performance issues with this latest patch, game freezes and stops the whole PC, Multiple cores pegged at 100 percent. I've tried a quick and slow repair made sure my drivers are updated, renamed my saved games folder, deleted all mods, made sure I'm not running in admin, deleated FXO and metashaders2, checked that hotplug is disabled, all the usual suspects. Please fix, DCS has been running smoothly for me for the last couple years. Whatever was introduced in the last two patches has made the game highly unstable. At this point the game completely freezes my PC on startup, and I can't get past the main menu. I can't even post crash logs because DCS doesn't think it crashed. I have to hard reset my computer.

I tried the save feature on a custom mission in the middle of the mission airborne at 30k ft going mach 1 and when I loaded up the save it respawned me on the ground cold and dark at a completely different airfield. What did I do wrong?

This discussion is both pointless and off topic as ED has already made multiple statements on what weapons are going to be included.

They have to be the same shape for LO characteristics to work on all three variants. That was kinda the whole point of designing one aircraft family instead of three discrete ones. I don't think it will be very hard for ED to plug in new dimensions for their CFD sim of it.

I don't imagine it's wildly different. In fact they have the exact same shape just in different sizes and proportions. Not like one is piper cub and the other is a B-52.

I'd say chances are high since it says its already mentioned as a possibility in the FAQ. The PVI is intentionally similar across all three variants so no need to re-invent the wheel with the cockpit and systems, and CFD can be used for major Flight model adjustments, Same power plant. I'd be really interested to see how the F-35C handles in BFM, Both on its own and in comparison to the F-35A. I Suppose the finer details would be in how/and where the FCS logic differs from the CTOL version beyond the obvious like 7.5Gs instead of 9 but specifically the high AOA regime and slow speed handling. The gun pod would be interesting to work with as well. Seeing the effect the big wings have on range would be cool too. Advanced features like the magic carpet should make it very easy around the boat.

Seems like your trying to jam up this thread.

Well you can't actually go STT without first entering a TWS mode in the real F-15. The exception being ACM modes. So yes it's first or primary mode when initiating an attack at BVR ranges.

So your wondering if NATO fighters can stop their own jammers? Pretty sure they can since they built them, and use them. ECCM is a Signal intelligence problem. So all they have to do is analyze those singles in a controlled environment and come up with a counter which they will have had to do to build them in the first place. So they probably would have an even better time against those systems compared completely foreign ones they may or may not have had a chance to see actually working. I definitely would expect EF-2000/F-35 suites to be more effective and cause more issues over contemporary aircraft like F-16/18 simply because they are newer and more powerful, I've heard claims the F-35s Electronic Attack modes can rival those of a dedicated EW aircraft.

What kind of jamming? How powerful? Surly bolt on self protection suites from the 1980s shouldn't do too well against a modern 2010s radar. Again F-15C has multiple ECCM modes. Specifically to counter jamming.
