    CPU Utilization... Again.

    in Game Performance Bugs

    Posted

    DCS primarily uses two cores, one for the physics, one for the audio. It does this for many reasons which have been covered before about latency in physics calculations, etc. Can it be overhauled to use more? Yes. Would that be time consuming and difficult? Yes. Would it yield huge boost in performance? No. Maybe a little, but not much.

     

    Source : ED saying they've considered making the switch but it's not worth the resources vs gain. They say they can get more bang for their buck through other avenues.

     

    As for it using one core over another... it doesn't make any difference whether it uses #1 or #12, or whether it rapidly cycles through them, or variations of the same. The one getting hammered is the one the primary physics engine is running on.

     

     

    That is not correct. It was shown that one can see performance improvement

    if the mission is not run on a single host but as client-server. Somebody close

    to ED told that they are looking into it - trying to run the mission as client-server,

    but on one host.

    Looking at your log2.txt i see this:

     

     

    2018-06-23 21:11:17.389 ERROR Lua::Config: load error C:\Users\James\Saved Games\DCS.openbeta\KNEEBOARD/001-caucasus-navbeacons-003.l

    ua:can't open './Mods/terrains/CaucasusBase/beacons.lua'.

    able overflow.

    If i read the timestamps correctly, there is a gap of approx. 7 minutes.

    Members with more experience than me can probably tell what

    "KNEEBOARD/002-missionbriefing-002.lua" should be or where to find it?!

    DCS World 2.x Multithreaded performance

    in General Questions

    Posted

    Right now, I believe it was said that shifting from Serial to Parallel Processing for DCS would require significant re-coding of the core, and it's not planned at the time, and the benefit will be marginal.

     

    If Wolle is correct with his client/host approach, then why not run

    as client on 2 cores and host on the next 2 cores, with client and

    host on one machine?

     

    Not long ago it was possible to run the offline and online program at

    the same time, using this "trick" to have the mission editor open in

    one instance and test the mission in the other, saving time.

     

    Going multi-core would require a re-design of the current simulation

    core and after that it would of cause scale better and be of better

    performance. Even without a complete re-design it would benefit,

    proove is the client/host approach.

     

    I can fully understand that the developers don't want to do that now,

    knowing the work it would require. The "mistake" was done long ago,

    going from Flanker to Lomac without re-design of the core engine.

    Dedicated Server?

    DCS World 2.0 in 2016 will offer new clouds and weather effects; improved HDR; deferred lighting (more light sources); new FLIR system; an improved Air Traffic Control (ATC) system; enhanced explosions, over-wing vapor, and rain on canopy; procedural grass and vegetation; improved multiplayer with dedicated server support; a new Air Combat Generator with enhanced user control of air-to-air generated missions; new custom overlays option for the Mission Editor, and a new Virtual Reality (VR) tab in Options which will improve the DCS World experience in VR.

    Low GPU and CPU usage but LOW FPS also...why?

    If this is the case then why are some people not experiencing this issue since according to your theory we should be experiencing the same issue whether you are running a 950 or 1080.

     

    Also for me reducing the draw distance and hence the number of objects did not remove the problem or show an improvement.

     

    Finally if this is the case then why can others with a near-identical rig to mine run the game with much higher settings (such as high shadows, high water, more visible trees, more clutter etc) without the game-destroying FPS drops?

     

    If others with identical systems run at higher fps it must be your settings?!

     

    I suggest to agree on one mission (like SU-25T free flight) flown to compare fps and it is surprising that nobody using Nvidia cards ever mentioned the pre-defined profile that is coming with their drivers. It is named "Digital Combat Simulator: Black Shark", but the executable is "dcs.exe", so i guess that profile is active?!

     

    Is "GeForce Experience" installed? I never installed it, because i distrust "automatically optimised pc settings for games". I use Nvidia Profile Inspector, delete pre-defined profiles and start from there.

     

    CPU (4770) usage 40% - yes, but that is leveled over 4 cores, one core 70 one 40 and the other about 25.

     

    GPU (980ti) usage 40-70%, resolution 2560x1440, 144Hz Gsync monitor, fps 70-144.

    Not sure if i understand you correctly.

     

    If you run the

    "Samsung SSD 840 EVO Performance Restoration Software"

    it will automatically update the firmware of the Samsung EVO and

    read/write the data on it. Problem is the decreasing read performance

    the older the files on disk are. Here's a link to tech mumbo:

    http://www.anandtech.com/show/8617/samsung-releases-firmware-update-to-fix-the-ssd-840-evo-read-performance-bug

     

    This update/fix has nothing to do with DCS or Windows updates.

    Just in case you own a Samsung EVO:

     

    Samsung SSD 840 EVO Performance Restoration Software

     

    Samsung is releasing a new firmware and performance restoration software package for the 840 EVO and 840 EVO mSATA.

    The firmware update is recommended to users who may have experienced any drop in read performance of the mentioned drives.

    Running the software packages provided will first update the firmware(840 EVO : EXT0CB6Q, 840 EVO mSATA : EXT42B6Q), then scan and calibrate all existing data on the drive.

    Note that the update time can be more than an hour depending on the amount of data. Please wait for the firmware update to complete before starting any other operations.
