Experiencing massive slowdowns?[edit | edit source]

Advice for slowdowns from a 9700k + 64Gb + RTX2080 user who was still getting slowdowns:

1. turn off vsync in btech settings and turn on "fast" vsync in nvidia control panel

2. add battletech folder to exclusion list for windows defender

3. add battletech.exe process to exclusion list for windows defender

4. make sure you use crystal clear when it installs roguetech went from 100% utilization of my gpu and 8fps min to 20% utilization and smooth 60fps

Process Lasso[edit | edit source]

Get process lasso ( only needs free version)

  1. Make sure it autostarts
  2. Launch RT, then in project lasso, right-click Battletech.exe and set the following:
    1. Priority Class>Always>High
    2. CPU Affinity>Always>Deselect CPUs 0 and 1
    3. IO Priority>Always>High

This should fix most stutters according to many users
