Major FPS drop when moving the mouse or changing camera direction (from 250 FPS to 70 FPS)
Acknowledged, NormalPublic

Description

I’m experiencing severe FPS drops in DayZ when moving the mouse or changing the camera direction. The game maintains a stable ~250 FPS when looking in one direction, but the moment I start moving the mouse to look around (especially in dense areas or cities), the FPS drops instantly down to 70 or even lower, with visible stuttering.

This issue happens consistently, even on low/medium settings, and only when moving the camera — not while standing still or walking in a straight line.


System Specs:

CPU: Intel Core i5-12400F (6 cores, 12 threads)

GPU: NVIDIA RTX 3070 Ti (8GB VRAM)

RAM: 16 GB DDR4

Storage: SSD (C: drive)

Mouse: Logitech Pro X Superlight (Polling Rate: 1000Hz → tested 500Hz as well)


Settings Tested:

mouseSmoothing=0;

rawInput=1;

sceneComplexity=100000;

preferredObjectViewDistance=800;

VSync: Off

Low Latency Mode: Ultra

Shader Cache: On

Also tested multiple polling rates (500Hz, 800Hz, 1000Hz) with no major difference. Windows "Enhance pointer precision" is disabled. No background apps interfering.


Steps to Reproduce:

  1. Launch the game and join any server (tested on both modded and vanilla).
  1. Stay still and look in one direction — stable 250 FPS.
  1. Move the mouse to turn the camera — FPS drops to 70 instantly.
  1. After stopping camera movement, FPS returns to 250.

Expected Result: FPS should remain relatively stable when rotating the camera or moving the mouse, especially on high-end hardware.

Actual Result: Massive FPS drop and stuttering only during mouse movement / camera rotation.

Hello kazeka4.
Could this be caused by some external software you are running or outdated/corrupted driver?

Chiming in here, because this has been an issue for literal YEARS.
It has absolutely NOTHING to do with external software or outdated/corrupted drivers. It most likely has to do with the fact that DayZ still runs on DirectX11 - as this issue can be almost entirely eliminated by running DayZ on a Vulkan API (I and many others have tested this firsthand).
AMD GPUs have had these issue worse than Nvidia for the last few years, but ever since 1.26, the issue is just as noticeable on Nvidia GPUs as it is AMD.
Most AMD GPU users have had to run specific drivers from May 2020 to get slightly better performance due to changes in how AMD GPUs handle DX11. Reported this one years ago.
I bought an Nvidia 4060 JUST to "fix" these issues back in September of 2024, and it genuinely did fix my frame issues until 1.26 was implemented. But let's get down to specifics about this issue, since I know for a fact I'm not the only one in you lot's ears about it right now:

The issue is most prominent in bigger towns that SPECIFICALLY have buildings taller 3 stories. (I BELIEVE the magic number here is 3, it could be 4). Good examples of this are the the standard apartments, tall apartments, Cherno's clocktower and the capital building in Novo.
Whether the issue with this is due to the building's height, or if its due to how many windows are on the building, I am not sure. Many people who have had this issue theorise that the amount of windows a building has influences the issue.

If you would like to see this issue in a very replicable environment - go to cherno and turn your mouse left and right as you look at the clocktower. This can also be done looking at the capital building in Novo. Standing on the outside most apartment complex in Topolin is a good place to replicate it as well. Standing on the apartments, look away into the field, and turn around until you are looking at Topolin. I will go from 160+ frames when looking away, to about 70 when fully looking at Topolin. This issue was not present on my Nvidia card until after 1.26.
Perhaps the vertex limit increase is somehow making the issue worse? These stutters/drops are also persistent throughout 1440p, 1080p, 720p, etc - they are most definitely not due to lack of system power. As I've tested about 4-5 different rigs over the years that all have this issue.

My current rig is as shown, if it helps: Ryzen 5800x, 64GB DDR, RTX 4060, 980 Pro m.2 SSD.

Giving this a bump. Would like to see this fixed.
