### Steps to Reproduce (Required):

1. Set DPI to 1600, and polling rate to 1000 hz
2. Enter game
3. Go into high shock damnation or auric level missions with lots of spawns
4. Wildly move mouse around, typically happens when doing a 180 quickly with a mouse to attack behind you.
5. Notice frame rate dips
6. Exit game, restart system.
7. Set DPI to 1600, and polling rate to 250, or set DPI to 200, and polling rate to 1000.
8. Enter game and repeat steps 4/5.

Multiple mice. Right now a razer naga v2 hyperspeed.  
This issue occurs regardless of mouse type. I have used a litany of mice attempting to find one that works well for me over the course of the last few years. Here is a list of them (all of them have had the same issue.)

Razer mouse naga v2 hyperspeed  
RAZER NAGA V2 PRO  
Aerox 9 Wireless  
SCIMITAR ELITE WIRELESS MMO Gaming Mouse (this mouse can only be set below 1000hz polling when in wired mode due to some limitation or issue with corsairs implementation. I ran it in wired mode.)  
DARKSTAR WIRELESS RGB MMO Gaming Mouse (Same issues as the scimitar above.)

This had been happening to me since the game launched. The beta release worked perfectly, after launch it was hell up until 11 months ago when I figured it out finally. At launch I was on windows 10, with 64gb of ddr4 3200 memory, 5950x, asus 3090 tuf. Since then I’ve moved to a 7800x3d w/64gb of ddr5 6000 memory, same gfx card, now on windows 11 r23.

I reinstalled windows multiple times on both 10 and 11 attempting and the issue persisted. Between mice I would uninstall the previous software set and move to the new set. I even used usbdeview to remove and uninstall unused usb devices and drivers. I’ve separated my keyboard mouse and other devices between different usb header chains. Removed all unused or redundant usb devices. ETC…

Dropping down to 500hz from 1000 was the only thing that got rid of the stutter.

Frame rate drops/hitches when new enemies or just the general chaos got to large in game can still cause problems but other tinkerings and fixes have resolved most of those.

> Issue Description (Required): In my pursuit of trying to fix my AMD GPU performance issues I believe I have found a reason why the game performance so poorly outside of exclusive fullscreen for some people (RIP KING). The game is not benefiting from Fullscreen Optimizations. To the FatShark Developers, I have provided what I believe to be proof that this is the case (as well as anecdotal performance improvements as well). This is separate to texture and mesh streaming issues that I have been in…

I’ve implemented these two sets of changes on my system and its really made a massive difference in the level performance I get out of my hardware. Smoothing out loading hitches when things get crazy and stopping or blunting he impact of normal framerate dips I usually get.

Also the implementation of direct storage that was added to the game makes things so much snappier. I had a match were I loaded in with just bots as no one quick played into the match due to the time of day. It was literally instant. I have a dual pcie-4 raid 0 setup of two sabrent rocket nvme drives that can hit 14gbs read speeds.

I’ve also enabled the “–lua-heap-mb-size 2048” change to help with the out of memory errors.

I know this is a ton of info and probably not all of it is relevant, hopefully it helps. I can track down any more specific info you need. Just let me know! And thanks for responding!

I will read through the whole text soon, but in the meanwhile.

I can reproduce the polling rate issue. It was simple so not sure why I got the report that we couldn’t repro it.

I didn’t do the initial tests so know I aquired the HW needed.

can you pinpoint what you did that they mention in these posts?

You got the problem wireless ? Using dongle 2.4 Hz ?

I was using the mice wirelessly yes. Though I still had the issue when running my corsair mice wired, as you cannot turn down the polling rate from 2000hz unless its wired.

The issue for me seems to either be gone or at the very least minimized to the point where its isn’t massively affecting me. I’ve settled on the razer naga hyperspeed v2 at this point. Thanks for the info though!

Odd. Maybe (re)install your motherboard drivers, and the mouse drivers? Update bios as well.
