resolved Multiple Error for DX11BACKEND

[[DE] T-Bone]

I am using DCS MT and since the last update I am having massive problems with crashes and freezes. 

So far I have tried the following:
- increased the size of the page file
- added regedit entries (TdrDdiDelay,TdrDelay)
- run memtest86 for several hours, no errors found
- deleted fxo/metashader folder
- removed mods and did a slow repair of DCS
- Uninstalled video card drivers, ran cleaner and reinstalled.

Now I have several DX11BACKEND errors in the log and DCS generates freezes and crashes as well as stutters of several seconds. 

I am running out of solutions... Whatever was done with the last patch has resulted in me not being able to use DCS on my system anymore.

as a test try to rename your DCS folder in saved games. then start DCS. the folder will be recreated. then you can copy over controls from previous folder to new folder.

I did this after the release of the F-15E to fix the desync problems. This helped with the desyncs, but not with the freezes/crashes....

Edit: 

I tried again and recreated the save game folder, was hoping that after the DCS repair that would still help.

Unfortunately no success, still crashes and freezes.

May I ask why you still have the folder C:\Users\PC-Re\Saved Games\DCS.openbeta\Mods after renaming the user folder? After all, this folder should not be.
One more question. Does the game crash in ST mode?

Since I still had crashes with the new blank saved game folder, I copied it back in. Therefore, in the last log the path to the folders is given because I made several test flights afterwards.

In the ST I also have the problems described above.

With the last crash came now additionally a BSOD.

OK, I just didn't see either "I have several DX11BACKEND errors" or any log without unofficial mods installed.
Try disabling Hyper-Threading in BIOS. It helped some users in this topic:

I have only AMD 3000/5000 systems and here it says SMT, I will give it a try and disable it.

If it helps with troubleshooting, I can do the saved game folder procedure again and create a log without copying anything into it. But the freezes and crashes were there unchanged, whether with or without mods.

**UPDATE**
SMT disables but still crashes and freezes.

Problem solved, DCS runs absolutely stable and performant again.

What have you changed to solve the problem?

I'm waiting for an answer to something similar here. What fixed it T-Bone?

OB crashes on me now but reboots the whole thing too. I've seen some DX11BACKEND errors too. Doesn't happen all the time but I keep hearing the usb unplugging and re-plugging even though nothing's been touched. DCS only.

After a long time of trying the solutions mentioned in the first post and others, it was finally the SSD on which DCS was installed.

I got the idea that this was the source of the error when I copied mod files for another game to a folder on this SSD. I use this drive exclusively for DCS and for mod files. Here, the copying speed slowed down to a standstill from time to time, and after more attempts, caused the drive to become inaccessible.

I installed a new hard drive and was able to copy DCS to it with some difficulty. After a subsequent slow repair, re-setting the page file and adding my old profiles, DCS is running stable again, no freezes, microstutters or BSOD....

Two thoughts on this:
1.Before the last patch DCS was running very stable and performant, apart from the known slow loading, and I also had no problems with the mods copied to disk.... it is illogical for me that the harddisk showed such a serious defect after the update.

2. A member of our squadron had the same phenomenon, and also here a move to another harddisk brought remedy for his crashes... and since his system is barely half a year old, I do not assume a hardware defect.

Well I’ll be…

Glad you got it sorted. Maybe I’ll check my drives too then.
