During the game DCS freezes a lot

[Myosotis1973]

Hello, I'm playing the Steam open beta version and my game freezes a lot. Is it the same on the editor version (standalone open beta)?

It is very often caused by two things:

1) Game is installed on HDD. - It is highly recommended to install game on SSD or it is not able to load data "on time"

2) Not enough Random Access Memory. - I highly suggest at least 16GB of RAM. The less RAM you have, the lower Preload Radius should be set.

Thing is: Preload radius is there to avoid freezes caused by HDD. But that needs high ammount of RAM. If it is set too high, the effect is contra productive. In that case it preloads more data than the RAM is able to take. That causes swapping (moving data to/from page file) which in result causes much deeper freezes than playing without preload radius.

So, the best result is:
Install game on fast SSD drive
Have enough of RAM. For high details 32GB and more.

One less common cause is the old data in the shader cachce. Try to delete folders "fxo" and "metashaders2" located in directory "%userprofile%\saved games\dcs". Those folders contains precompiled shaders. By deleting those you force the game to compile new shaders which will be better optimised to your system and drivers.

Thanks T.Norris, I too am having this issue, will test these suggestions.

I already have 32 gb of RAM and DCS is installed on a SSD 2"5.

O.k. That should help a lot. Better to use NVMe SSD but SATA SSD is still good enough. Is your operating system also installed on SSD? Also try the second advice. Rhird thing you may try is to manually set the page file size to around 32GB.

DCS is installed on another SSD than OS but I think it will better with NVMe SSD.

from your post history you seem like have issues across multiple games.
maybe do some troubleshoot on the machine. make sure no thermal throttling or something.

In DCS you can press Rctrl+Pause Break enable FPS indicator, when freeze happens, how long each "freeze" last. please take screenshot what those freeze and look like in FPS window.

dcs specific suggestions:
you can turn off USB hotplug in DCS, it prevents windows freeze the game on certain motherboards while scanning new devices.

and set windows power management plan to "high performance" prevent CPU power down

In fact, since I updated the bios to the first level, that is to say with the very first updates, my DCS no longer crashes and no longer freezes. In fact, I learned something today about the bios: never touch it yourself even if you don't know too much about computers.
