PC Building Simulator 2: Fixing the 3DMark Calculator — A Detailed Guide
PC Building Simulator 2 (PCBS2) players rely on accurate benchmarking tools like the in-game 3DMark calculator to estimate GPU performance, price-to-performance, and to validate builds. When the 3DMark calculator is producing incorrect or inconsistent results it can mislead purchasers and frustrate players. This post explains likely causes, step-by-step fixes, and preventative tips — suitable for modders, players, and content creators who want reliable metrics.
2. Thermal Throttling Simulation
The most requested feature. In the old version, you could run a CPU at 120°C with a stock cooler, and the 3DMark score would remain static. Now, the calculator reads the thermal data from the PCBS2 engine. If your CPU hits 95°C during the "Physics Test" portion of the simulation, the clock speed dynamically drops, and the score reflects that real-time throttling.
2. Bottleneck Detection (The "Fix")
One of the hardest things for new players to understand is why a good GPU scores poorly. The Calculator includes a Bottleneck Meter. pc building simulator 2 3dmark calculator fixed
- CPU Bound: If your CPU is too weak for the GPU, the tool flags "Bottleneck: CPU" and suggests a better processor.
- Thermal Throttling: Predicts if the current cooling solution is insufficient for the TDP of the CPU/GPU, which would lower the score.
- RAM Speed: Calculates the performance penalty for using single-channel RAM or slow MHz speeds.
Why This Matters
This feature transforms the gameplay from "Trial and Error" into "Engineering and Strategy." It rewards players who understand hardware synergy and removes the frustration of failing a career job because of a slight miscalculation in part pairing.
What "Fixed" Actually Means in Patch 1.2.5
When the developers announced they had fixed the 3DMark calculator, many assumed it was just a number tweak. It was not. They rebuilt the system from the ground up using a real-time weighted algorithm based on public benchmark data (PassMark and Geekbench 5 aggregates).

Here are the specific fixes included in the patch:
How It Works (Gameplay Loop)
- Accept Job: Client wants a PC that scores 12,500 in 3DMark Time Spy.
- Open Calculator: Instead of building blindly, you open the tool.
- Select Parts: You drag an RTX 3060 and an i5-12400F into the virtual slots.
- Read Result: The tool predicts a score of 11,800.
- Adjust: The tool highlights that the RAM is the issue. You swap DDR4 2400MHz for DDR4 3200MHz.
- New Result: Prediction updates to 12,550.
- Build & Verify: You build the PC, run the actual benchmark, and the score matches the prediction (within a small margin of error).
📊 Example (Fixed Calculation)
Build: Ryzen 9 7950X + RTX 4090 + DDR5-6000 CPU Bound: If your CPU is too weak
- CPU Multi Score: 42,000 × 1.15 (core factor) × 1.08 (RAM) = 52,164
- GPU Score: 68,000 × 1.0 (VRAM factor) + 0 (no OC) = 68,000
- Final 3DMark: (52,164 × 0.45) + (68,000 × 0.55) = 60,874
In-game expected result: 60,000–61,500
