    Do you have unified GPU usage monitering enabled? What poling rate are you using?

    GPU usage readings could be somewhat corrected using unifying monitoring as Rex said.

    About FPS "gangnam style": Try Shadow boost, set 120 as
    FPS limit in shadowboost.ini and 122 in RTSS.

    Shadow boost can REALLY help with DX 11 api overhead and his effect over FPS.

    Worth a try.

    In this game even 60 FPS in cities is not sustainable without it.

    Disable godrays and don't use TAA.

    using 1000 polling rate and yes I normally use unified gpu monitoring, but in the above graph i turned it off just once to see the levels of each card individually to see what was what.

    The thing is though, I can be standing in Sanctuary just stationary, have 82% on both GPU's sitting at 100FPS plus, then all of a sudden the both cards usages just drop through the floor for no apparent reason.

    The "no apparent reason" has a name: DX11 API overhead.

    AMD bad performance in this and the old Fallout 4 engine and very bad optimization sum in the bad effect over FPS stability.

    Use shadow boost.

    As far as i know, Afterburner sometimes might give you incorrect readings of the GPU usage while using CrossFire. This is the reason that the unified GPU usage monitoring option was added. This will give you a much better reading. Without unified GPU usage you might get incorrect readings. So you should take the results you are getting with a grain of salt. I for instance, can't get a correct reading without unified GPU usage monitoring enabled. It's always bouncing up and down from 99 - 0.

    wow what a difference, now using Shadow Boost makes

    GPU usage now is actually holding steady, not jumping all over the place, and getting upwards of 100fps quite alot, towns drop down into the 80's and 90's but wow what a difference. This was quite a foggy scene, using the True Storms mod, but just look at that lovely number. This is Ultra with low God Rays at 1440p

    Thank You very much.

    Finally you hear me! :D

    Can you post your VRAM usage, committed RAM (global) and committed RAM by Fallout4.exe process while playing?

    I'm really interested to see the difference the 8 GB VRAM in 390s makes on commit requirements.

    Thanks to take your time for that.

    Interesting...relatively low VRAM usage and commit charge with Fallout 4 so 8 GB VRAM vs 4 GB VRAM is not an important factor at least at the res you use.

    I guess ROTTR with very high texture setting at 1440p or 4K could be very different but that's a different story. :)

    I use imgur for pics this free web service has a lot of pic resize options as output links and roks well.

    To be able to see AB OSD inmedium or small size pics you can change the size of OSD font in RTSS for the Fallout4.exe profile.I use it when i want to post 4K/8K/12K downsampled pics of some games at a reasonable size for web forums and still see the OSD numbers.

    Why do you guys still run this over 61fps? I should post a vid of my game. Tons of mods, shadow boost, enb just for performance. Everything on highest even god rays. Things as smooth as butter. My new 5775c eats this game up.

    because I've a 144hz 1440p freesync screen, higher the better. So damn smooth up past 70fps, ideally between 100fps and 120fps is a game changer.

    Hello Everyone,

    I am searching for some help with my Fallout 4. I am getting absolutely terrible performance with my machine and I cannot figure out why. I am using everything on Ultra except I have TAA off. I am also using ShadowBoost but it doesn't seem to be doing much of anything. When I fast travel to the "high-density" area of Boston my draw-calls soar to over 55,000 at some points and I only get about 10 FPS. This is with the latest AMD driver (16.1.1 Hotfix 2) that has the working Crossfire Profile. Can anyone give me any advice as to what I should do to increase my performance?

    Thanks!

    Which is the monitor res?

    VSR?

    I am running the game at 3440 x 1440, and I am not using VSR. Although I may have just solved my problem accidentally. I started the game without any mods enabled and I was getting about 40 - 45 FPS in the same area that I had been getting 10 FPS with the mods enabled. This is very peculiar though as none of the mods I have installed are supposed to be performance impacting.

    Also please excuse my while I update my rig. I am actually running a whole new system now.

    Thanks!

    - Insan1tyOne :)

    Maybe somethings wrong with ShadowBoost or isn't configured properly. Try delete it and put the shadows distance to medium in game settings. In the ini file the value for shadow distance should be 3000.

    I will try that... Right now in my ShadowBoost.ini it just says the default which is 3000 min and 15000 max? I also have it set to target 58 FPS as I have the 60 FPS framerate cap enabled.

    So how it reach 55,000 in Boston?

    Try enabling mods one by one to find the offender.

    It could also be a mod incompatible with another.
