05Questions
Q.01Is Demon's Souls Stable?
Yes. Quality-mode runs complete end to end, including boss arenas, on the reference configuration.
Q.02Why does 4K dip in one archstone?
That area is VRAM-heavy. Drop to native 1440p or close background apps; see GPU and VRAM.
Q.03Wired or wireless controller?
Wired DualSense over USB for parry timing. Bluetooth adds measurable latency.
