Pc Building Simulator

PC Building Simulator is the one game in our database where the subject matter and the benchmark data describe the same thing: it is a game about assembling gaming PCs, played almost entirely by people who own one or are planning one. Claudiu Kiss and The Irregular Corporation shipped the full release in January 2019 after a short early access run, and seven years later it sits among the easiest titles to run in our entire library. Across 3,723 measured CPU and GPU combinations, the average system records 138 FPS at 1080p Ultra, 87 FPS at 1440p Ultra, and 46 FPS at 4K Ultra. The fastest combinations in our data reach 501 FPS at 1080p Low, and the slowest still manage 36 FPS at 1080p Ultra. That floor is the headline: even the weakest hardware we have ever tested against this game produces a playable frame rate at maximum settings. The real question for this game is never "can I run it" but how far past 60 FPS you want to sit, and at what resolution.

A light Unity engine with honest, predictable scaling

PC Building Simulator runs on Unity, and it is one of the engine's gentler workloads. The game renders small, mostly static environments: a workshop, a desk, a PC case on a workbench, an office. There are no sprawling draw distances, no crowds of simulated characters, no physics chaos, no streaming open world. The processor's job each frame is modest, and while Unity leans on single-thread performance as it always does, the total amount of work is small enough that virtually any CPU from the last ten years clears it with room to spare. In our data this shows up as near-perfect resolution scaling, which is the signature of a GPU-bound game. Moving from 1080p to 1440p adds about 78 percent more pixels and costs about 37 percent of the average frame rate (138 down to 87). Moving from 1440p to 4K more than doubles the pixel count again and knocks the average from 87 to 46, roughly in line with the pixel math. When frame rate tracks resolution that cleanly, the graphics card is doing nearly all of the limiting, and the CPU, memory, and storage are along for the ride. Memory requirements are similarly relaxed: 8 GB of RAM is genuinely enough here, 16 GB is comfortable headroom for a browser and Discord alongside the game, and anything beyond that does nothing for this title specifically. Storage speed matters only for load times, and the game's footprint is small. If your machine runs Windows comfortably, it is most of the way to running PC Building Simulator comfortably.

1080p: high refresh for almost everyone

At 1920x1080 with every setting maxed, the 138 FPS average across 3,723 combinations means the typical gaming PC is not asking whether PC Building Simulator will run, but whether their monitor can show all of it. This is one of the few games we cover where a 144Hz monitor is a sensible pairing for mid-range hardware, because triple-digit frame rates at 1080p Ultra are the norm rather than the exception in our tables. The spread tells the rest of the story. The slowest combinations in our database, the oldest and weakest CPU and GPU pairings we have measured, still average 36 FPS at 1080p Ultra, which is console-grade smoothness on hardware that has no business running modern games at all. At the other end, flagship combinations push 501 FPS at 1080p Low, deep into territory where the frame rate counter is the only thing that notices. Between those poles sits the practical reality: any dedicated graphics card from the mid-range upward in the last several generations will hold 100 FPS or better at 1080p in this game, and even entry-level cards and strong integrated graphics land in the playable-to-smooth range with minor setting adjustments. If you are building a budget gaming PC specifically with lighter simulation and indie titles in mind, this game is Exhibit A for why you do not need to overspend.

1440p and 4K: the graphics card does all the talking

At 2560x1440 Ultra the average drops to 87 FPS, which is still comfortably high-refresh territory, and at 3840x2160 Ultra it falls to 46 FPS, the only number in this game's profile that requires any thought. That 4K average sits below 60, which means 4K Ultra is the single scenario in PC Building Simulator where hardware choice genuinely matters. A mid-range graphics card handles 1440p without complaint; 4K at a locked 60 or better asks for an upper-mid-range card or higher, and 4K high refresh is flagship-only territory. One honest caveat for settings hunters: the 2019 original predates the upscaling era, so there is no DLSS or FSR toggle in the menu. You tune this game the old-fashioned way, with resolution and quality presets, and given how light the workload is, that is rarely a hardship. If upscaling matters to you because you are driving a 4K display from modest hardware, the cleaner fix is dropping two or three expensive settings rather than chasing a resolution scale, since the visual difference between High and Ultra at a desk-camera distance is small. The sequel, PC Building Simulator 2, is a meaningfully heavier game with a more modern feature set, so do not assume the numbers on this page transfer to it. They do not.

Settings: what actually costs performance

The settings menu in PC Building Simulator is short, and the cost hierarchy is the usual one for a light Unity title. Shadows are the first thing to cut: shadow quality is consistently among the most expensive options relative to what you see on screen, and at the game's typical camera angles, a step down from Ultra to High or Medium is nearly invisible while you are routing cables. Ambient occlusion and post-processing effects are next on the list, small visual contributors with a real frame rate cost on weaker cards. Anti-aliasing is worth keeping at some level because the game's appeal is looking at clean hardware renders, and jagged edges on a GPU shroud you just installed are oddly offensive in a game about admiring components. Texture quality can stay high on any card with 4 GB of VRAM or more; the scenes are small and the texture load is modest, so this is free visual quality on almost everything except ancient 2 GB cards. Our recommended configuration for weaker hardware is simple: textures High, shadows Medium, ambient occlusion off or Low, anti-aliasing on, post-processing Low. That profile recovers a substantial chunk of frame rate over Ultra while looking nearly identical in play. One more piece of advice that applies to every tier: cap your frame rate. A game this light will happily render 300, 400, or 500 FPS on strong hardware, and all that buys you is fan noise, coil whine, and heat. Lock it to your monitor's refresh rate and let the system idle.

What hardware do you need?

Tiering advice for this game is almost comically generous, but here it is, anchored to the measured data.

Entry level (integrated graphics or a very old dedicated card, 8 GB RAM): this is the tier that produced our 36 FPS floor at 1080p Ultra, and that is the worst case we measured. Drop shadows and ambient occlusion and even this class of hardware plays the game properly. If you are on integrated graphics, the one upgrade that matters is memory configuration: running two sticks in dual-channel rather than a single stick measurably lifts integrated GPU performance, and it is the cheapest frame rate you will ever buy.

Mid-range (a modern 6-core CPU, 16 GB RAM, a mid-tier GPU): 1080p Ultra at triple-digit frame rates and 1440p Ultra around the 60 to 100 range, right on the 87 FPS average. This is the sweet spot, and the honest answer to "what is the best graphics card for PC Building Simulator" is simply whatever current mid-range card fits your budget, because the game will never be the reason you needed more.

High-end (strong modern CPU, 16 to 32 GB RAM, upper-tier GPU): 1440p high refresh and 4K at 60 or better. Overkill for this game alone, sensible if it shares the drive with heavier titles.

Flagship: the tier that produced our 501 FPS ceiling at 1080p Low. For PC Building Simulator specifically this is money spent on other games, which is a perfectly good reason to spend it, just not this one.

Laptops: the friendliest game in the library

Most popular games punish thin laptops; PC Building Simulator does the opposite. Its light CPU load means thin-and-light machines do not thermal-throttle into stutter, its modest GPU demand means modern integrated graphics handle it at reduced settings, and its small memory footprint means 8 GB ultrabooks are not automatically disqualified. A budget gaming laptop from the last five years runs it at 1080p Ultra without raising its fans to full speed, and even a decent office laptop with a current integrated GPU manages a playable experience at Medium settings. It is also an unusually good travel game for exactly these reasons: short sessions, low power draw, and no penalty for playing unplugged the way demanding games impose. If there is one laptop-specific note, it is the dual-channel memory point again, since many thin laptops ship with a single stick or soldered single-rank memory, and integrated graphics are starved by it. On a machine with proper dual-channel DDR5 or LPDDR5, integrated play is noticeably smoother.

Streaming and content creation

PC Building Simulator has a real streaming niche, since build-along content, repair roleplay, and hardware comedy all suit the format, and it is close to the ideal streaming game from a hardware perspective. The CPU is barely working, which makes even x264 software encoding viable on a modern 8-core processor, something we would never recommend for a CPU-heavy title. The cleaner option is still a hardware encoder: NVENC on Nvidia cards or AMF on AMD produces a clean 1080p60 stream with effectively zero performance cost, and on a game this light there is no excuse for a laggy broadcast. The one real piece of advice is audio and scene setup rather than performance, because the game will never be the bottleneck in your streaming setup. The audience overlap is worth noting for the workstation crowd too: a machine specced for video editing, with a many-core CPU, 32 to 64 GB of RAM, and a strong GPU for timeline scrubbing, runs this game so far beyond its needs that the frame counter becomes comedy. If your PC earns its living in Premiere or DaVinci Resolve during the day, PC Building Simulator is the least demanding thing you will ever ask it to do.

Common problems and fixes

Extreme frame rates in menus, coil whine, fans spinning up in a light game: the engine renders as fast as the hardware allows, and on strong cards that means several hundred FPS of wasted work. Cap the frame rate to your monitor's refresh, in-game or through the driver, and the noise and heat disappear.

Stutter or long pauses when the game loads new scenes or parts: storage, almost always. The game is small enough that an NVMe SSD makes load screens brief, and moving the install off a mechanical drive is the single biggest quality-of-life fix available. There is no reason for this game to live on a hard drive in 2026.

Career progress lost or a save that will not load: rare but reported over the game's long life. The career save is a local file, and backing it up occasionally costs nothing. Steam Cloud handles this for most players, but manual backup before major updates is cheap insurance.

Workshop mods causing slow loads or odd behavior: the Steam Workshop integration is one of the game's long-term strengths, but large mod lists extend load times and outdated mods can break after patches. If the game misbehaves, unsubscribe from everything, verify the install, and add mods back in batches.

Alt-tab or multi-monitor weirdness: borderless windowed mode behaves better than exclusive fullscreen on multi-monitor setups, as with most Unity titles of its era. Performance is so far above requirements that the borderless tax costs you nothing.

Upgrade priorities

For PC Building Simulator alone, the correct upgrade budget is close to zero for most players, which is a strange and pleasant thing to write on a hardware site. If you are below the experience you want anyway, the order is short. First, storage: an NVMe SSD if the game sits on a hard drive, because load times are the only friction this game has. Second, memory configuration: dual-channel memory if you are on integrated graphics, since that is where the real frame rate lives at the bottom of the stack. Third, the graphics card, and only if you are chasing 4K or high refresh at 1440p; at 1080p almost anything dedicated is already enough. A CPU upgrade sits last by a wide margin, because the game simply does not ask processors to work. If you find yourself planning a CPU upgrade for this game, stop and re-check what is actually limiting you, because the answer is almost certainly not the processor.

Frequently asked questions

Q: Is PC Building Simulator CPU or GPU intensive?

A: Neither, by modern standards, but when something limits frame rate it is the GPU, and only at high resolution. Our scaling data (138 FPS at 1080p Ultra, 87 at 1440p, 46 at 4K) tracks pixel count closely, which is the classic GPU-bound pattern. The CPU barely matters.

Q: Can I run PC Building Simulator on integrated graphics or a basic laptop?

A: Yes. The slowest, weakest combinations in our entire 3,723-combo database still average 36 FPS at 1080p Ultra. Modern integrated graphics with dual-channel memory play it comfortably at reduced settings.

Q: What is the best graphics card for PC Building Simulator?

A: Whatever current mid-range card fits your budget. It handles 1080p and 1440p Ultra with ease, and only 4K or 240Hz ambitions justify spending more. Buy your GPU for the heaviest game you play, and this game will come along for free.

Q: Does PC Building Simulator support DLSS or FSR?

A: No. The 2019 original predates mainstream upscaling and has no DLSS or FSR option. The game is light enough that you tune with settings presets instead, and shadows plus ambient occlusion are the cuts that pay back the most.

Q: How much RAM do I need for PC Building Simulator?

A: 8 GB genuinely works, 16 GB is comfortable headroom for multitasking alongside it. More than that does nothing for this title. If you play on integrated graphics, two sticks in dual-channel matter far more than total capacity.

Q: Do these numbers apply to PC Building Simulator 2?

A: No. The sequel is a substantially more demanding game with a different performance profile. Treat this page as data for the 2019 original only.

The bottom line in 2026

Seven years after release, PC Building Simulator occupies a comfortable niche: it is the hardware hobby turned into a game, kept alive by a steady trickle of new PC enthusiasts, Steam Workshop content, and the peculiar satisfaction of cable-managing a virtual build when your real one is overdue. Its performance profile makes it one of the least demanding games we track, with a 138 FPS average at 1080p Ultra, a 36 FPS floor on the weakest hardware we have ever measured, and a 501 FPS ceiling on the strongest. The practical meaning of that data is liberation: this is a game you never have to plan around. Whatever you own runs it, whatever you are building next will crush it, and the only hardware decision it ever forces is 4K, where the 46 FPS average is the single number on this page below 60. For a site built on benchmark anxiety, PC Building Simulator is the palate cleanser, a reminder that not every game is trying to melt your rig. Some of them just want you to appreciate what is inside it.
