Housemarque has released version 3.0.3 for the PC port of Returnal with performance optimizations and bug fixes. DLSS and FSR upscaling quality improved, reducing ghosting artifacts during fast camera movement. Lower-end hardware sees improved stability with fewer crashes during biome transitions.
A rare co-op desync during boss encounters has been fixed. Keyboard and mouse controls have additional sensitivity options for aim-down-sights. A memory leak that gradually degraded performance during extended sessions has been addressed.
Our trainer works without issues on this patch. All cheats including infinite health, unlimited consumables, and max currency are confirmed functional. Co-op mode works with the trainer enabled, though both players need it installed independently. Test in solo mode first before joining co-op.
