    F.A.Q.

    Q. I can't locate the right path where to paste the Engine.ini
    A. Just press Win + R and copy/paste the following path in the box it will appear if you have Xbox / Game Pass version:
    %localappdata%\MW5Mercs\Saved\Config\WinGDK
     
    or this one if you have Steam/GOG/Other versions:
    %localappdata%\MW5Mercs\Saved\Config\WindowsNoEditor

    then hit enter and you will end up in the correct folder where to put the Engine.ini


    Q. When I launch the game the modded Engine.ini is automatically deleted or reverted to default one?
    A. Right-Click on my Engine.ini -> Properties -> make sure the "Read-Only" box is selected -> Apply/OK
    It's important. If the file keeps getting deleted or reverted, un-tick the "Read-only" box -> Apply -> re-tick it -> Apply/OK

    Q. When I right click on Engine.ini Properties I have a security warning stating "This file came from another computer and might be blocked to help protect this computer"?

    A. That's just a warning that tells you the file comes from another PC (mine). It will still work without issues.

    Q. My CPU usage is skyrocketing to 100% after the mod
    A. This is initial shader compilation which may continue in-game even after the initial precompilation loading screen. Wait 4-5 minutes at max to let the game finish it and CPU usage / performance will return normal.

    Q. I have noticeable ghosting
    A. To improve ghosting I highly recommend updating the game's DLSS .dlls to latest DLSS4 version (easiest method: DLSS Swapper) and force the "Latest" DLSS preset via NVIDIA Profile Inspector or NVIDIA App. It will make an huge difference for the better.
    Also always use the latest version of the mod.

    Q. I have the same or worse performance after the mod
    A. For super high-end PCs the performance difference may be small but you should still notice reduced stuttering, more consistent 1% lows, lower input latency and better visual clarity. For mid and low-end PCs the fps difference may be much bigger on top of all that. 
    If for some specific PC configs you end up with worse performance try deleting shaders cache including the files which end with "cache" located in the "Saved" folder from the above path and open the game again.
    If you still have worse performance just delete my Engine.ini and on next boot the game will recreate its default one.
    You don't need to verify the game files or reinstall it to restore it to what it was before the mod.

    Q. Will this mod downgrade visuals/graphics?
    A. No :)
    "Lossless" means this mod was created with the goal to optimize everything I could in Unreal Engine without sacrificing visuals and/or altering your in-game graphics' choices (except for Chromatic Aberration and Film Grain removal which you can still revert back by changing their described lines within the Engine.ini itself)
    With improvements to AA, Sharpening, DLSS/FSR/XeSS you should actually have even better visuals after the mod.

    Q. Can I use it together with MW5M Optimiser, MW5M Ultra+, MW5M "Uber-Tweaks" or whatever?
    A. No.
    Don't mix my Engine.ini with other mods which will do their own optimization tweaks to the engine or they may conflict with each other.
    You can try each of them separately and choose the one which performs the best for you and only use that exclusively.
    You can still install any other "non-optimization" mods.

    Q. Will this Engine.ini disable Achievements?
    A. Straight and simple: no. :)

    Q. Will this Engine.ini work/load also with future game patches?
    A. Yes. Just be sure the file is set to "Read-only"

    Q. The game crashes when opening it and/or during gameplay after a while
    A. Make sure your PC is actually stable under sustained load (e.g. you are not using an excessive overclock/undervolt). You can test it using OCCT (launch a 1 hour "CPU+RAM" test, followed by another 1 hour "3D Adaptive" test. If you have even a single error, you need to fix your PC stability first)
    Another solution if you use Vortex is to open it, go to the game section -> Load Order and click the last button ⛔ on the top bar ("Reset Plugins File")
    If even doing the above you still crash, try lowering PoolSizeVRAMPercentage=60 (both in [TextureStreaming] and [ConsoleVariables] sections of the .ini), then remember to set the .ini to Read-only again.

    Q. Where do I see a full Changelog for all the updates done to the mod so far?
    A. Just go to the mod Description page and click the "Changelogs" button.

    Thanks for the updates, the newer versions further improved the frame stability a lot.
    I'm running 79 mods and now my game can handle it without issues.

    This helped tremendously with my trash bin pc to run smoother thank you. I literally made it read only and got butter smooth fps now excluding when new units spawn in...but I'm running 60 mods so that's a yaml thing so far.

    gotta love how the "change log" is bigger than the .ini itself lol and how professional sounding. very subtle. and impressive!

    I know that the description states that no other "optimization" mods are allowed. I am not a modder so I don't understand all of the details, but wouldn't xenoargh's series of mods work along with the .ini tweaks that you have made? I'm specifically referencing the following:

    Art Optimiser 3,0: https://www.nexusmods.com/mechwarrior5mercenaries/mods/685
    Optimiser 4.0: https://www.nexusmods.com/mechwarrior5mercenaries/mods/444

      Thanks for the response. I'm just wondering if anything jumps up out at you about the concepts of these mods being likely or possibly incompatible.

      From what we've found in testing, this engine ini configuration will break things in various mods, so using it with mods is a bad idea.

      Can you expand on that for me? In what sort of mods are conflicts to be expected? Is the YAML suite safe for instance?

      Lol it absolutely is not safe. 
      There's a reason it's on the discord's list of "get rid of" things, alongside LOM and LOTS

      I understand that people say it is not safe. I was just wondering in what way it is not safe. As in, how exactly in causes problems I thought might be useful to understand.

      I would just try it directly and if there are issues you can just delete the modded Engine.ini and everything will be exactly as before using it (as the game will recreate its default one), no permanent harm or need to reinstall the game or other mods.

    Great tweaks!

    Any chance you could add a section to disable Motion Blur same as you did with Film Grain and Chromatic Aberration?

    Cheers.

      Hello, thanks for continuing to build the enhanced ini file.  I loaded v35 and most of the game screen was black.  The menus on the ship were visible, but everything else was black except the relative position marker in the Starmap (which was also visible in the mechbay).  Mechbay was also all black.  Restored v34 of engine.ini, and the issue went away.  Restarted game and tried v35 twice before reverting.

      Can you try removing these lines from v3.5 Engine.ini and see if you still have the issue?

      r.SceneRenderTargetResizeMethod=1

      r.VirtualTexture.EnableCompressZlib=1

      Yes, that seemed to do the trick.  I didn't test a mission, though.  Been fooling around in the mech lab for a few days.

    Hey there.

    Is there a way to leave more arbitrary features such as film grain and chromatic abberation be or could you point me to how to restore them?

    Those go beyond plain optimisations and into the realm of noticeable 'visual aesthetics.

    The mod Ultra Graphics and Weather makes tremendous difference to the game's visuals and uses both to great effect.

      Yes, just open my Engine.ini with Notepad and you'll already find instructions if you want to keep them ;)

      Nice one, thank you!

      By the by, I'm assuming you don't necessarily know or play MW5 much yourself - all of your mods appear to be UE optimisations for various games - but would you happen to know of any obvious problems and incompatibilities with Ultra Visual and Weather mod in mechwarrior specifically? 

      Despite the word 'ultra' is not an optimisation mod, but a graphical overhaul that hacks volumetric clouds and other goodies into the game.

      I usually don't recommend mixing my (heavily) modded Engine.ini with other optimization mods, but if other mods only touch graphics and weather without optimizing the engine you can try to mix (or merge) them if also those are in an Engine.ini, but I not guarantee they will work well together.

      Sure thing. This one offers no optimisations and does not touch engine.ini as far as I'm concerned.

      Will test and report if something's off.

    You have 2 install paths listed, one for Steam and the other for Windows Store/Xbox. I have Gamepass and am using the WS version, but that path doesn't exist for me... the Steam one does though. Not certain if those folders got merged between the versions at some point or something, but I'm assuming I should just use the Steam install location.
