OpenBeta 2.5.6.55960 often crash

Hi,

I have the modules A-10C, A-10CII, F/A-18C, Supercarrier.

Flying the A-10C with each of last three updates DCS often crash:mad:.

Crashs occurs in different moment, time, actions ...

I enclose the last log files.

Thx for help

Hi, you seem to have an issue between DCS and your graphics card (DXGI_ERROR_DEVICE_REMOVED). It can be due to overclocking or sometimes to a misplacement of the gfx card in its slot. Do you have an overclocked GPU or an overlocked RAM?

You also appear to have a very small pagefile (less than 5 GB). You should try customizing Winfows pagefile, 16 GB min, 32 GB max.

Hi Flappie,

I increased the page file to 16GB.

My graphic card is AMD Radeon RX 5700 XT (8GB) I use the las Adrenalin (Radeon software) setting tuning in Automatic -Default mode VRam clock speed is 200Mhz in quiet mode when DCS is running the clock speed increase to 1.750Mhz the max frequency is 1.900Mhz.

I will check anyway the graphic card slot.

Thanks

OK. Adrenalin overclocks your GPU then (base clock is 1605 MHz). If you keep having these crashes despite a 16 GB pagefile and after checking out the slot, please try disabling the Adrenalin automatic overclocking function. DCS is not always keen on overclocking.

Let us know how your PC is doing.

Hi Flappie,

now I'm like this:

- page file 16GB (I can go to 32GB it's better ?)

- Adrenalin in Autotuning "Default" so no extra Overclock GPU neither Overclock VRAM

DCS is running on 4K monitor at 30FPS I enclose the graph setting, if uou have any suggestion to speed a bit ..

I tried some mission and all is right .. apparently.

I will try soon the exaclty mission where DCS cashed and I will

update you.

Glad your DCS hasn't crashed yet.

My W10 automatically gives a 32GB pagefile whenever I start DCS. This is probably done so because I have 32GB of RAM, ans this seems perfectly logical. Yet I see Windows acting differently to many users and I have no clue why. Often, W10 only lend 4 or 5 GB of pagefile, which seems to piss DCS quite a lot.

So yes, you can raise your pagefile min size to 32GB minimum (example: min size = 32GB, max size = 32 GB) as long as the SSD containing your pagefile has enough free space.

Until Syria came out, I wouldn't need to optimize my DCS much, because I play at 1920x1200px with a 1080Ti and 32GB of RAM. But now is the time for me to tweak things a little bit, since my FPS drop severely over Syria.

My 50 cent:

1/ You have a 4K resolution, which is very precise for the human eye: disable useless GPU post-processing like FXAA, Gamma correction, AA transparency, SSAA, SSLR...

2/ Set your graphics driver to maximize power (instead of optimizing power) and see if you get better FPS.

3/ Read this guide (even if it's a bit old now) if you want to tune DCS graphical options. Try and see if Motion Blur OFF and/or Shadows MEDIUM give you better FPS.

Hi Flappie,

I moved to 32GB!

I will follow the advices, and thx for the guide I will read deeply.

For the moment no crash :)

Hi Flappie,

update.

DCS don't crash anymore :)

I follow the guide and I acheve 60fps but some time I have jerks on the ground images ...

No more crashes? Great news! :thumbup:

What are you calling "jerks"? Stutters?

Sorry for delay ... et for my english ..

I means that the images dont flow smoothly

OK. How often do you get stutters? Like one episode every 3 minutes, or only when you're looking at things on the ground? Are there many ground units in your missions? In solo or mulriplayer?

I have feeling as images flow is slow. More accentuated when on the ground there are many object. In solo mode, I haven't checkd in multiplayer

Try disabling "Hardware accelerated gpu scheduling" in Windows settings.

I have not this option

In settings -> system -> display -> graphics settings the option isn't show.

nor in the register file the "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers\HwSchMode" not exist ...

I thought it would be there because your log shows you have W10 update 2004, which has introduced this new feature. And I see your PC has a recent AMD driver.

Have you already tried emptying both your FXO and Metashaders2 folders, so DCS can renew them? If not, give it a try please.

C:\Users\your_name\Saved Games\DCS\fxo

C:\Users\your_name\Saved Games\DCS\metashaders2

If the issue persists, please attach a screenshot of your AMD graphics settings.

Emptying the two folder the situation improve, anyway I attach AMD and DCS Settings screenshots. If you can give a look

Good. Now try disabling ingame V-sync and activate "Radeon Enhanced Sync" in the AMD settings panel.

So now really better I also passed the Anisotropic filtering from game to AMD i will play some time and I report you.

Thanks

Also I discovered that surface format optimisation should be off. It lowers fps without any visible improvements on my system.

@milit

I will try thx for signal
