• Description of Issue: 
  
  My in-game camera lags and then suddenly accelerate. This is a different issue than the mouse icon lagging on menus that I believe was the fix provided during the server slam.
  
  I have a Razer Viper V3 Pro and I use 1600 DPI, however I had to turn it down to 800 DPI to be able to play the server slam normally.
  
  I read that polling rates above 1000Hz were causing this issue, so I changed this from 4000Hz down to 1000Hz, but this didn't fixed the issue.
  
  The only thing that worked for me was reducing the DPI setting from 1600 down to 800. I use the Razer Synapse app to change the DPI and polling rate.
  
  I wasn't recording the screen, neither had any type of overlay active. For example: Nvidia Shadowplay, Xbox Game Bar, Steam Overlay, Discord Overlay, Discord Clipping, Discord Activity Sharing, RivaTurner Statistics Server (MSI Afterburner). I made sure all of this were disabled.

• Repro steps 
  
  1. Set the preferred DPI setting (1600) in the Razer Synapse app for Razer mouse (Viper V3 Pro); 
  2. Open the Marathon Server Slam; 
  3. Search for a match; 
  4. Once it loads into a match, move the camera around.

Hope you guys can find a fix for this before launch, since 1600 DPI is very common and most modern mice and first person shooters support up to 8000Hz polling rate and +30K DPI.
