Game Science pushed out v1.4.0 today and this one is focused almost entirely on boss balance and performance. Several of the Chapter 5 bosses had their attack windows tightened, which honestly makes them harder, but they also increased the parry window by a few frames across the board to compensate.
The Wandering Wight boss that everyone complained about got a health reduction of about 15 percent on normal difficulty. His grab attack hitbox was also shrunk -- it was genuinely unfair before this patch.
Performance-wise, they finally addressed the memory leak that would cause stuttering after about 2 hours of play. VRAM usage in the Yellow Wind Ridge area was reduced significantly. Ray tracing performance is still not great but it is better than it was.
For trainer users, heads up -- this patch shifted a bunch of base addresses around. Our team is currently updating the trainer and most cheats are working, but the spirit skill cooldown modifier is broken right now. We expect a fix within 24 hours. The infinite health, one-hit kill, and soul multiplier cheats are all confirmed working. Just make sure you update to the latest trainer version before launching the game.
