Real Performance Gains Confirmed
Independent testing by MxBenchmarkPC on YouTube using an RTX 5080 and Intel i7-14700F revealed significant frame rate improvements. At 4K with Very High settings, the October 23 patch delivered up to 20% FPS gains, while optimized settings using Auto-Detect Graphics Preset showed around 10% improvement.
At 1440p with DLSS set to Quality mode and optimized settings, frame rates jumped to 90-100 FPS—finally making the game feel smooth on high-end hardware. With DLAA mode, performance stayed above 60 FPS consistently. The footage showed little to no hitching, resolving the frame drops that plagued earlier patches.

Halloween Event: Horrors of Kairos
The limited-time Horrors of Kairos event adds two exclusive Legendary weapons—Murmur Tediore Assault Rifle and Skully Order Grenade—as world boss drops across Kairos. These rewards deliver directly to the Reward Center and don’t affect other loot drop rates, giving players bonus gear without diluting existing loot pools.
The event runs until November 6, providing two weeks to farm these Halloween-themed weapons. Players can also grab a free SHiFT code (announced separately) for themed cosmetics.
Multiplayer and Stability Overhaul
Gearbox addressed multiplayer performance issues when large numbers of homing projectiles appeared on-screen—a common problem during boss fights with multiple players. Improved matchmaking and session stability reduce disconnections, while fixes for PS5 friend lists and console SHiFT account linking enhance user experience.
The Gravitar builds that caused performance slowdowns and prevented UI updates or Fight For Your Life sequences from completing have been patched, restoring functionality for affected players.

Quality-of-Life Wins
Specialization Respec costs dropped from 5,000 Eridium to 1,500, making build experimentation far more accessible. The Lost Loot Machine now prioritizes higher-quality gear when full, collision gaps and invisible walls were patched, and Echo Location guidance improved across missions.

FAQs
Will the performance improvements fix my low FPS on older GPUs?
The 10-20% boost helps, but Borderlands 4 remains GPU-intensive; mid-range cards may still struggle at 4K without DLSS.
Are the Halloween event weapons limited-time only?
Yes, Murmur and Skully drop only during Horrors of Kairos (Oct 23-Nov 6); claim them before the event ends.
