先说文明6的具体情况。我在日本参与过一个SLG项目的AI优化,恰好研究过文明系列的AI架构。加油呀文明6的AI决策流程大致分三层:战略层(科技树选择、胜利条件判断)、战役层(unit调度、城市管理)、战术层(single round move、battle calculation)。这三层里,真正吃单核的是战术层的path planning,尤其是后期几百个units同时做A*寻路时,complexity是O(n²logn)级别的。但战略层和campaign layer的一些计算,比如AI evaluate tech value、diplomacy weight adjustment,其实可以 parallelize——问题是Firaxis的engine对multithreading usage is very conservative,I remember civilization 6最多 only use up to 4 physical cores,and there’s also lock contention between main logic thread and rendering thread.
So when you say “single-core hell” it’s indeed true, but the blame isn’t entirely on hardware. The AI architecture of civ6 itself wasn’t designed with good multithread optimization, which is a legacy issue from their game engine in 2016. Geekbench single-core score over 4000 is impressive, but if the game engine still forces 90% of the logic frame into one thread, then even stronger single-core performance can only give linear improvement. Going from bubble-noodle time to tea-time might be possible, but achieving “second-opening” seems unrealistic unless Firaxis completely rewrites the AI scheduler.
Also regarding ARM architecture’s power efficiency advantage. You mentioned TDP is lower by about half, I’d like to add some data here: Apple M-series chips have single-core full-load power consumption around 3-4W, while x86 mobile counterparts need to reach 15W+ for similar performance. This energy efficiency ratio does make a significant difference for handheld devices where battery life is crucial.
From my perspective as someone who frequently plays strategy games on portable devices, this discussion highlights an important point that future improvements should focus not just on raw computing power but also on software-level optimizations. Game developers need to leverage modern multi-core architectures more effectively instead of relying solely on faster clock speeds. It would be great to see next-gen strategy games designed with better threading models from the ground up, taking full advantage of today’s hardware capabilities.
加油呀
For current players stuck with older titles like Civ6, maybe we could explore community-driven mods that attempt to improve threading utilization? Or perhaps lobby Firaxis directly to prioritize these kinds of backend optimizations in future patches?
What are your thoughts on how feasible those approaches might be? Have you encountered any particularly well-optimized strategy games recently that handle multiple cores efficiently?
