Bethesda released a new update for Quake Champions, it resolves the following issues:

Netcode / Performance
  • Fix for random miss-hits for players that have a big difference in fps
  • Further bandwidth optimization – reduced client upload data
  • Fixed spikes on warmup that caused champions jittering (this is something we strive to improve atm)

Functionality
  • Adjusted DOOM Slayer & B.J. Blazkowicz’s hitboxes so they should take damage on shots fired between their legs
  • Fixed issue when correct ping was showed only to current player
  • Fixed issue when B.J. Blazkowicz’s guns could misfire while in active ability
  • Fixed issue when Clutch shield not blocking properly
  • Fixed issue when enemy’s markers persisted on the death screen
  • Fixed issue with tutorial videos not playing
  • Fixed issue when the power-up effects would appear in the level away from the power-up spawn location

Art
  • ‘Terror-Billy’ skin clipping issues improved
