Noteworthy Crash Fix

I have done some research and have figured out how to

STOP ALL MY DCS CRASHES!

All of you having problems are in luck!

Those DCS stopped responding or has caused an error and needs to close!

Sometimes it crashes constantly when refreshing multiplayer servers.

Needs a reboot, and even then still doesnt work consistently.

Other times when just joined a server and choosing an aircraft, and crash!

Or fly for an hour and crash! :(

So, here are the 2 main fixes! Enjoy! No More Crashes!

This will also speed it up! And other games too! :)

First fix for 32-bit only, let the program use more RAM:

For Win Vista/7 simply Copy/Paste or Type Exactly into CMD:

bcdedit /set increaseuserva 3072

And Reboot.

For Windows XP 32-bit, use these instructions:

Second fix, has to do with DEP, just dont worry what it does, it's magic! :)

Copy/Paste or Type Exactly into CMD:

bcdedit.exe /set {current} nx AlwaysOff

Reboot.

This turns off DEP for all programs and lets DCS freely use your system, so to say, it's awesome and it works!

To REVERT IT and STOP the fix, type this and reboot

bcdedit.exe /set {current} nx AlwaysOn

bcdedit.exe /set {current} nx OptIn

Not a single crash since I did this myself on Win7 32.

I just cant use my MS SideWinder Precision Pro with USB and only Gameport and only in 32bit and these commands have saved me!

NO MORE CRASHES!

Let me know if this worked for you or not.

My guess is that it will! :)

It does not work for DCS.exe DEP off, try it.

Did not work for me, it said error, has to be enabled for DCS.exe

Have to disable for all.

Hehe, I titled it originally as Fix for 90% of Crashes, but I havent had a single crash, so for me, it's for all crashes, thus far. :)

I think people would have more trust if you explain what DEP is.

With " just dont worry what it does, it's magic!" nobody will give it a try.

What about users with 64 bit win7 ?

Win XP/Vista/7 64=bit use only Fix #2

Copy/Paste or Type Exactly into CMD:

bcdedit.exe /set {current} nx AlwaysOff

Reboot.

DEP http://en.wikipedia.org/wiki/Data_Execution_Prevention

This seriously works, also for games like GTA.

Also do this:

1. DELETE ALL FILES IN THESE LOCATIONS CTRL A SHIFT DEL KEY:

Location 1: C:\Users\[userName]\Saved Games\DCS\Logs\

Location 2: WinKey+R Run: %temp%

2. RUN REPAIR DCS WORLD from the START ALL PROGRAMS MENU.

If the program is complete and these fixes are done, try to make it crash!

Please report here if helped or not.

well done

thnx scorpion!

been wanting to turn off that damn DEP for a while now

like you i found it could not be turned off for executables? WTF?

i am one of your 32bit brothers, so much appreciation!

Be aware, blindly turning off DEP can expose your machine to being compromised via any number of drive-by exploits. DEP serves a useful purpose, it's not just put there to annoy you.

Secondly, increasing UserVA may have unintended consequences, particularly if you have a lot of RAM but are forced to use a 32-bit O/S. Go and read about system page table entries (PTE's). Running out of system PTE's will cause blue screens. This problem gets a LOT worse when you adjust the userva setting.

The only way to fix all DCS crashes is to uninstall the game and burn your hard drive.

We have a few members that often seem to have semi-random crashes. Gonna ask them to test this and report back with the results.

wasnt the 32-bit fix posted by mustang a looooooooooooong time ago.

And didnt I suggest disabling AV Real Time Protection and DEP for DCS and it's folders a few major updates back?

Only to get a bunch of people telling me I didnt know what I was doing, blahdy blahdy blahdy. and sending me negative rep for bad advice..

Glad some people listened and learned.

It must be in at least a dozen member's sigs, too.

EDIT: ...and the DCS Warthog FAQ.

Q: I have a 32-bit OS and I am having problems running the game. What should I do?

A: If you use Win 7 \ Vista 32-bit, please read this: http://forums.eagle.ru/showpost.php?...20&postcount=8

A: If you use XP 32-bit OS, please use the /3GB Switch. Direction are here: http://forums.eagle.ru/showpost.php?...9&postcount=38

wasnt trying to call out the OP, just sayin', that fix/adjustment has been around for a while.

and to add,

I disable UAC and DEP, as they both block alot of programs I use from the XP Era from installing or running.

As long as you be smart about where you go on the internet and what you install you should be fine, I survived 12+ (ongoing still) years on XP with no UAC or DEP of any kind, so I dont need it on Windows 7.

Agreed. No offense to the OP intended.

Well, seems like disabling DEP only for DCS is a no go, since MS have decided to pseudo implement exceptions. Using my awesome Google skills I've found out that if you want to be 100% sure DEP is off you need to disable it all together.

We're gonna try this tonight, on a custom made mission we had LOTS of crashes in a few days ago. I'll be back with reports tomorrow.

i know i disabled it in XP day one 2001, so.

you can leave it on, turn it on for programs except or turn it off all the way.

I just turn it off 100% and leave it off.

So, have you had any crashes lately?

Nope.

Oh, don't get me wrong, not saying that disabling DEP and messing with userva won't help. Just saying that there may be unintended (and pretty big) consequences, so be aware of it.

Matter of fact, setting userva will probably help with DCS since it's pretty RAM hungry. But be careful if you have a lot of RAM, and if you start seeing weird blue screens you're probably running out of system PTE's.

Yes I used the 3GB switch in Windows 7 32bit back in 2011 when I was struggling with FC2 and posted it up to help others (so glad I left 32 bit behind for 64!)

Sadly, that does happen (I see it a lot in real life) and yeah, it is nice when they adopt what was said... sad when they claim it as their own though.

Turning off the DEP only masks a problem with the software (which kicked it in) though
