Fixes
All Platforms
- Frostbyte Flaw: Rarely, enabling NVIDIA DLSS Frame Generation could cause pink screen rendering. The glitch has melted away!
- Talking Troubles: In some cases, squad voice chat would malfunction at match start, preventing mic use. Communication has been restored! Assemble and strategize!
- Daywalker Drag – Blade’s Frame Drop: Resolved a problem where using Blade’s Blade Of Khonshu – Eclipse Edge Team-Up Ability could lead to extended frame rate drops. The vampire hunter is back to slicing and dicing at full speed; no more lag in the line of duty!
Heroes
- Rocket’s Portal Payload: Fixed a bug where Rocket Raccoon’s Bombard Mode Damage Falloff was miscalculated when passing through portals, resulting in less-than-heroic damage. Now, Rocket’s rounds rocket through space-time with maximum impact!
