WinOrLose Posted March 18 Posted March 18 Hi - can anyone help decipher this gobligook please Only started in the last few weeks - screen freezes then eventually crashes.

sleighzy Posted March 19 Posted March 19 (edited) I've dropped your logs into the DCS log analyzer which had the following to say: There is a GPU-related error Remove any overclocking from your GPU. Uninstall your GPU driver with DDU and install a clean one. Some GPUs come with factory overclocking, so use something like MSI Afterburner to check for this and remove it if reinstalling your GPU driver doesn't resolve this. This aligns with the massive amount of spam of DX11BACKEND (9500): failed to create structed buffer. Reason: DXGI_ERROR_DEVICE_REMOVED See this DCS FAQ on this: https://www.digitalcombatsimulator.com/en/support/faq/startup/#3312253 In addition to this: Hot plug Events Disable hot plug in your CONTROLS section. It also states that you should turn off core isolation. It also looks like you're running a version of DCS that is a few patches behind. 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) You should also turn off core parking.

Hi Thanks for looking. I'm running the latest patch so not sure why it would say otherwise. I thought I had Hot Plug off already but will check. I have not overclocked the CPU but can look at the drivers. No idea what core isolation is so doubt it is on. What I find strange is I haven't changed any settings my end and this has only started since the last patch.
KH0000 Posted March 20 Posted March 20 (edited) I got a crash on the PC after a launch DCS just completed the update on steam after load into the main menu the screen and the cursor just freeze all the input pattern were ineffectived instead of force re-boot anyone get same problem？ Microsoft Windows 11 Home, Version 10.0.26100 DirectX runtime version: DirectX 12 CPU: 12th Gen Intel(R) Core(TM) i9-12900K RAM: 64.0 GB Storage (2): SSD - 3.7TB ,SSD - 953 GB Graphics card GPU processor: NVIDIA GeForce RTX 3080Ti Laptop + circumscribed RTX 3070 I solved it out which cause by the custom UI size in the system setting and the DPI sync use the defualt setting and the DCS been fine Edited March 21 by KH0000 solved FL KH0000 Block.II SQN FL:VF-0 of Fly to A&E

This is on by default in Windows 11 (it didn't used to be in Windows 10). You can search for it in your Windows settings, Google should also have some steps for it. As to the GPU overclocking, some GPUs come with factory overclocks, believe you can use MSI Afterburner to check for this as well. Hopefully just reinstalling the drivers works fine for you. 7 hours ago, fagulha said: Yes first time i launched DCS after update it crashes loading a instant mission.

You should raise your own forum post, or take this to the Eagle Dynamics DCS Discord, instead of putting this on somebody else's post. Your problem sounds different. Also attach your DCS log files when a crash occurs so we can see what happened. 1 AMD 7800x3D, 4080Super, 64Gb DDR5 RAM, 4Tb NVMe M.2, Quest 2

Disable Hot Plug - this was already off. Core Isolation - this was already off. Latest patch - this was already installed. I appreciate I need to check the first point but why do you think it was reporting errors that did not exist? Regards

The log analyzer bases this on plug/unplug events, which normally occur when hotplugging is on and it constantly scans for new devices and sees them being plugged/unplugged.

Constant plug/unplug events can cause performance issues and stuttering in the game. Sometimes this can be caused if these devices are connected via USB but don't have enough power, e.g. need a powered hub, or if power management isn't disabled for the USB controller in device manager which means it can causes them to sleep/awake. The log analyzer lists a couple of items that may or may not be an overall issue, the core isolation one I think falls into that bucket, as a suggestion for looking at, it can't confirm if that it actually the case but raises it for awareness. The crash is definitely GPU related however based on the results. Edited March 20 by sleighzy 1 AMD 7800x3D, 4080Super, 64Gb DDR5 RAM, 4Tb NVMe M.2, Quest 2

I do have items plugged in via USB, joystick, throttle mouse etc so will check for loose connections, pretty sure I set the power management appropriately but will check. Thanks again for your help.
