perhaps this is a memory issue? add a static pagefile of 32 GB. you also may be running into a limitation on the processor. i see other posts when searching this in various non DCS forums. nothing definite. it seems to me that the shaders are buggy. an error such as this will affect DCS in Windows too. i would suggest going back to my earlier post to rename the DCS folder in saved games to allow DCS to recreate it. you could also try to delete the shader folders within that folder. \Saved Games\DCS\fxo \Saved Games\DCS\metashaders2 delete either all contents of the folders or the entire folders

my system has max 128 GB ram installed. i also have a static 32 GB pagefile. perhaps a placebo. however, i do not have any memory related shortcomings in DCS. it does not hurt anything to have it.

how is new drive connected? that does sound slow.

bingo hiob. many people do not realize that search db is different from operational db. the search db is created by incremental crawls to find the differences. i believe dcs is using the crappy forum backend searching. this likely would not change anytime soon. i commend y'all to make the effort to educate in the use of google. obviously a superior search.

@AstroEma - i agree with @Rudel_chw. this is what i did to my system. i purchased a new 4 TB drive and a USB cradle because my 2 TB was getting close. in my case i used acronis that i already owned. i was able to clone the drive while running in about 1 hour. windows will not even know it happened except for a new device.

hello. do you perhaps have language packs installed? this update is mentioned in other forums. this could be cause of high FPS. not specifically high CPU usage.

hello. just a thought. have you edited the mission at all since the latest patch? sometimes a patch will change mission parameters and needs to be tweaked. to make it easy, just edit the bits / flights that are experiencing the issue. i suggest making a copy of your mission first.

i see from your path, you are running DCS in linux? i did not pick up on your original post mentioning Ubuntu. is steam play setup properly?

there is probably corruption in the content you copied. there have been no others reporting this patch removing the folders. did you try to run DCS with the saved games folder empty? once you get the new folder populated, all you need to do is piecemeal copy certain folders from the backup. not enmasse. copy \Saved Games\DCS.openbeta\config\Input first. then try the sim again.

@Tiramisu - i am concerned that your Saved Games DCS folder is now empty. is there another folder somewhere else? maybe on another drive? any backups? by design, when there is no Saved Games DCS folder, DCS will see this and make a new one with all default settings.

hello. can you share the MIZ you are using? if it is a big mission with a lot of units, give some specifics of the flight in question.

they should create the dcs.exe that opens when clicked from shortcut that says "WRONG EXE STUPID; USE BIN FOLDER"

get the resolution width of each monitor. in DCS you are basically making one very wide monitor. then you have to modify an LUA with the appropriate parameters. this forum may have your answer. https://forum.dcs.world/forum/999-multi-display-support/ i have one monitor so i cannot share my file with you. say i have 3 exact monitors 3440x1440. 3440x3 (10320) would be my number.

along with the others answers. i have noticed that sometimes when nvida adds some sort of new setting, an upgrade of the driver introduces weird issues. as stated, you can use DDU to remove everything related to the driver. then install the new one should get you sorted. also even though you likely made no changes after an upgrade of the driver, just taking note of your current settings, defaulting the driver state, and then re-adding your settings may clear it up.

interesting. the value of this setting in my lua is 1.0. i am pretty certain it is the default that was installed with DCS. ExternalKeyboardAccelerationSlow = 1.0 there is a readme.txt in that folder that warns not to change the file in the root folders but instead to save a copy to saved games and edit it. DO NOT EDIT stock game files. Your local changes should go to C:\Users\<YOUR PROFILE>\Saved Games\DCS\Config\View\ Please, copy the file(s) to this folder (create if neccessary) and keep your changes there.
