The Killer 2100/Xeno Pro employed an LSP (Layered Service Provider). While this is beneficial in allowing the Killer software to enable offload and lower latency, it has been found to be incompatible with some games, thus creating instability or crashes. If you are experiencing any crashes while playing games, it is recommended that you ‘unmap’ the LSP. Prioritization and other Killer features will continue to function.
This is done with the following steps:
Start an administrative command prompt and type or paste this command:
C:\Program Files\Bigfoot Networks\Killer Network Manager
…then press Enter. This should resolve instability with online games.
