PC Building Simulator FPS Calculator & System Requirements

PC Building Simulator is a Unity-based simulation game focused on assembling virtual PCs, which requires moderate GPU power to render detailed 3D components and workshop environments. To run the game your PC must reach a CPU performance score of at least 25 and a GPU score of at least 22. As a visually intensive title, PC Building Simulator rewards hardware above the recommended threshold — particularly for ray tracing, high-resolution shadow maps, and ambient occlusion. At the recommended tier (CPU 52, GPU 50) expect around 60 FPS at 1080p on high settings. Enter your CPU and GPU in our calculator for a personalized estimate.

PC Building Simulator lists these minimum specifications: CPU — Intel Core i5-2500K or AMD Athlon X4 740; GPU — NVIDIA GeForce GTX 660 2GB or AMD Radeon R9 285 2GB; RAM — 4 GB RAM; Storage — 30 GB available space; OS — Windows 7 64-bit or higher. At the minimum tier, expect the game to run at low or medium presets with frame rates around 30 FPS at 1080p. Demanding scenes — dense environments, complex lighting, or heavy particle effects — may dip below this. Disabling ray tracing and lowering shadow quality deliver the highest performance recovery on minimum-spec hardware.

For the best PC Building Simulator experience, the recommended specifications are: CPU — Intel Core i5-3570 @ 3.40GHz or AMD Athlon 300GE; GPU — NVIDIA GeForce GTX 760 Ti or AMD Radeon HD 8990; RAM — 8 GB RAM; Storage — 30 GB available space. This hardware level targets smooth 60 FPS at 1080p on high settings with stable frame times. Enabling ray tracing, high-resolution shadow maps, and ambient occlusion simultaneously calls for a GPU above the recommended tier. If you are targeting 1440p on ultra presets, check our FPS calculator for the exact scores required.

On hardware meeting PC Building Simulator's recommended specifications, expect around 60 FPS at 1080p on high settings. Enabling ray tracing, ultra shadow resolution, or screen-space ambient occlusion can reduce that figure by 15–30% depending on your GPU. Minimum-spec hardware typically achieves 25–40 FPS at 1080p on low-to-medium presets. Moving to 1440p costs roughly 30% of your 1080p frame rate, and 4K approximately 50–60%. Enter your exact hardware in our FPS calculator for a personalized estimate across every quality preset.

For high graphics settings in PC Building Simulator at 1080p, your GPU needs a performance score of at least 50. The officially recommended card is NVIDIA GeForce GTX 760 Ti or AMD Radeon HD 8990, which targets 60 FPS at 1080p. Enabling ray tracing on top of high settings demands significantly more GPU headroom — plan for a score well above 50 if RT is a priority. For 1440p on high settings, a GPU scoring around 65 or better is advisable. The FPS calculator lists every compatible GPU ranked by expected performance for this title.

PC Building Simulator requires a CPU with a minimum performance score of 25 — roughly the level of Intel Core i5-2500K or AMD Athlon X4 740 or better. For a smooth experience without CPU bottlenecks, target the recommended score of 52 (around Intel Core i5-3570 @ 3.40GHz or AMD Athlon 300GE). As a graphically rich title, it can stress the CPU in densely populated areas, complex physics sequences, or large set-piece moments. A CPU at the recommended score paired with 8 GB RAM ensures the processor does not throttle your GPU's potential output in those scenarios.

At 1440p, expect roughly 25–35% lower frame rates than 1080p in PC Building Simulator. On hardware at the recommended tier (GPU score 50), this translates to around 42 FPS on high settings. To maintain 60+ FPS at 1440p, target a GPU scoring around 65 or higher. Use the FPS calculator above to get a precise estimate for your specific CPU and GPU combination at 1440p across every quality preset.

4K demands roughly 55–65% more GPU power than 1080p in PC Building Simulator. On the recommended GPU (score 50), expect around 25 FPS at 4K on high settings. Reaching a consistent 60 FPS at 4K requires a GPU scoring around 83 or better. Upscaling technologies like DLSS 3 or FSR 3 can recover 40–60% of the resolution overhead with minimal visual cost on supported hardware.

Integrated GPUs are not officially supported, though the game may launch on some integrated graphics hardware. For a stable experience with acceptable frame rates, a dedicated GPU such as the GTX 660 or Radeon R9 285 is strongly recommended.

The game has limited native ultrawide support. Some players report success with 21:9 resolutions via manual config file edits, but multi-monitor spanning is not officially supported and may cause UI scaling issues.
