High CPU & low GPU usage; microstuttering in BF5
This shouldn't be happening on a core i7-7700 and GTX 1080 along with 16gb of RAM. Yet, for some reason there is a horrible microstutter every second while turning and sometimes at the start of a level the textures load slowly and constantly pop in and out especially on trees. In wide open areas GPU usage can drop as low as 46% and the CPU is nearly constantly pegged at 85-100% load across almost all 8 threads. Changing the settings from medium to low/high/ultra doesn't do anything. Future frame rendering option is set to ON, rendering API is dx11; game is even worse on dx12. Also noticed: 1)The game resets any changes made in nvidia control panel back to default on launch, 2) The game exits to desktop a full 7-8 seconds after selecting quit, during this time the UI is completely responsive. Driver version is 445.87 along with all latest windows updates. Uninstalling and reinstalling the game didn't work, deleting directx shader cache didn't work. Only "fix" for now is reducing the refresh rate to 60 and putting up with input lag.
Just a few comments:
- When I say stock I say stock from Nvidia and Intel, not whatever the bios sets to default. That means your 7700 runs at 3.6 GHz, and the 1080 runs at 1607 MHz and no undervolts.
- Setting that high max temperatures on the CPU and GPU I'm not so happy about, some chips can cause stutter under high temperatures and workloads.
- Youtube processes the video at 360p first and then 1080p is done a little later - just be patient.
- I can't see much from your video except some texture pop-in which is to be expected with 3GB video memory used and very high cpu temperatures. You should see here https://answers.ea.com/t5/Technical-Issues/How-To-Write-amp-Get-Responses-for-Your-Technical-Issue/m-p/7160970#M360 how to enable BFVs built in overlays and record a video with that - enabling frametime graph in Afterburner is also always a good idea if you like using that app in the future.
- Your CPU usage seems normal, BFV likes 6+ cores and you have 4 so usage in the 90%s is to be expected, especially at 1440p.
- A Windows installation can always be the issue, no matter how many other games it runs fine.
- No game utilizes a CPU the same way, you might have 35+ games but have none of them use the CPU instruction sets the same way as BFV does. This also means that games that utilize your CPU more percentage-wise might still stress the CPU less in other ways compared to BFV - the percentage is not everything.
In short, my guest guess for your issue is instability caused somehow by your hot 4 core CPU. You might also consider limiting the max framerate to something lower than average like ~60-90 just to see if the extra headroom limits the stuttering.
