Dragon's Dogma 2 has been plagued by performance issues since its release in March, especially when you wander around the game's towns. Unlike most performance issues which are GPU-related, Dragon's Dogma 2 was bottlenecked by CPU power, and now we know why.
In an interview with Japanese outlet Famitsu (translated by Automaton), the development team dove into some of the specifics of what's causing Dragon's Dogma 2's performance issues.
"In Dragon’s Dogma 2, CPU power is allocated to process the thoughts of each NPC as well as the effect on character physics. Therefore, in scenes where many NPCs appear at once, like in towns, the CPU load would get extremely high, which in some cases affected the frame rate," the team said. "Since CPU was our bottleneck, GPU-related solutions like lowering the resolution had little effect on improving frame rate."
Essentially, the NPCs of Dragon's Dogma 2 are processing too much information, which is sapping performance. The good people of Vermund and Battahl have a lot on their minds, and it's affecting the stability of Dragon's Dogma 2. To improve this issue, Capcom has tweaked how NPCs handle these processes, easing the load borne by the CPU...
