Left 4 Dead — requirements, current state and what is inside

This page lists the official minimum and recommended PC requirements for Left 4 Dead (released Nov 17, 2008), split into the fields the listing actually states. Everything below is read from the store listing for this app; where a field is missing it is shown as missing rather than filled in.

This site has only been recording for 1 day(s), so there is nothing to compare against yet. No week-on-week figure is shown until there is one.

This is one snapshot taken per day from Steam's public concurrent-player endpoint, kept as a series on this site. Two things it is not: it is not a 24-hour peak (that needs hourly sampling, which this site does not do), and a low number does not mean a game is bad — single-player games are routinely played offline. The comparable question it answers is whether the number is drifting up or down.

Can your machine run it?

This check reads what your browser is willing to report about this device, then compares it field by field against the requirements below. It runs entirely in your browser — nothing is sent anywhere and nothing is stored.

This panel needs JavaScript. With scripts off you can still read every requirement on this page and compare it by hand. When it does run, it prints your own machine next to the game's requirements — nothing more:

  • It reads: your operating system, whether your system is 64-bit, how much memory your browser reports, your logical core count, and your graphics adapter.
  • It cannot read: VRAM, CPU model, free disk space, DirectX version or driver version — no website can. Those rows are shown as not readable rather than guessed.
  • It does not decide. It will not tell you whether the game runs. Side by side, the comparison takes you a second to make; a score would only be a guess dressed up as an answer.

Where the two tiers actually differ

同一个字段在”最低”和”推荐”两档里分别写了什么。这张表由该游戏自己的数据算出来，不是通用模板 —— 别的游戏差别在别的地方。

What these numbers actually mean

  • 显卡跨度值得注意：最低写的是 128 MB, Shader model 2.0, ATI 9600, NVidia 6600 or better，推荐写的是 Shader model 3.0, NVidia 7600, ATI X1600 or better。前者能开起来，后者决定你能否在中高画质下保持流畅 —— 两者之间通常还差一到两个档次的显卡。
  • 该游戏有 2 条配置说明没有按”字段名: 值”的格式书写，因此无法结构化对照 —— 这一项我们保持原样列出，不做推断。

How to read the confidence labels

LabelMeaning
【A】来自官方接口或商店页面的实测值，不是推算
【B】本站自己的观测记录（每天记一次，逐日累积）
【C】由上文实测值推算出来的，规则写在该条旁边

What this page does not tell you

  • 它不预测帧率。官方配置要求是”能否运行”的门槛，不是”运行得多流畅”。
  • 它不评价显卡档次。本页只转述官方写了什么，不把型号换算成一个”性能分”。
  • 它不包含折扣分析。本站的价格记录才开始积累，样本量还不足以支持任何折扣结论。

价格、平台与配置数据由公开商店接口取得（appid 500），本页由脚本生成、随数据更新； 游戏名称与商标归其各自权利人所有，本站与该游戏发行商无关联。
