Surprisingly intuitive and pretty smooth on consoles
TheGamerWithKids
A great game
The PS4 version seems to run pretty smoothly and playing with a controller is pretty darn simple.

PC Building Simulator is by far one of the best games or rather a tool to give us noobs an insight into PC building.

Pingle × Irregular Corporation
About the game
PC Building Simulator is a detailed simulation where players get a chance repair, build, and benchmark PCs in a virtual workshop.
Within a month of Early Access on Steam in 2018, it cleared 100,000 sales and turned a niche concept into a hit. Irregular Corporation didn’t wait to expand its reach, and on August 13, 2019, PC Building Simulator debuted on PS4, Xbox One, and Nintendo Switch.

About Pingle × Irregular Corporation partnership
Irregular Corporation partnered with Pingle to port their PC-native Unity project to consoles. We had to adapt core PC mechanics for gamepad control and adjust the game to work within the hardware limits of PS4, Xbox One, and Nintendo Switch.
/ The Challenge /
Make a hardware-intensive PC sim work stably on PS4, Xbox One, and Switch
PC Building Simulator was initially designed for PCs. On consoles, thousands of detailed components, high-poly models, and complex shaders pushed hardware to its limits, which caused freezes, lag, and broken immersion. We had to fix these bottlenecks and deliver the same authentic workshop feel on PS4, Xbox One, and Switch.
Our team had to deal with the following issues:
- Fix freezing and memory leaks caused by object upload/delete cycles.
- Improve data uploads for metadata queries.
- Resolve visual artifacts in console-specific builds.
- Corrected PC part behavior to match real-world physics.

We can help!
/ Phase 1 /
Freezes and memory leaks begone!
The original Unity build constantly froze and leaked memory on consoles because entire objects, like PC components or textures, had to be added during gameplay. It caused instability and disrupted the overall gaming experience.
Here’s what we did to achieve stable gameplay:
1
Cut the number of processes required to complete the game objectives.
2
Created duplicates of the required game objects without meshes.
3
Retrieved necessary data from these duplicates instead of manipulating the full objects.
Result: No stutters or sudden crashes when interacting with the workshop or switching PC parts.
/ Phase 2 /
Optimizing assets for stable console FPS
Detailed PC parts, high polygon counts, and complex textures overwhelmed console GPUs and led to slow performance and frame drops. We optimized game assets, which in turn increased FPS and ensured stable play on consoles.
1
Optimized code to reduce CPU load.
2
Lowered polygon counts and adjusted textures where possible without visible quality loss.
3
Implemented object culling for tiny PC details that didn’t impact realism.
4
Built a custom system for dust culling that balanced visual atmosphere with console performance.
Result: Stable frame rates even with high-detail components on screen.
/ Phase 3 /
Developing the asynchronous scene and details upload functionality
Every PC part and workshop object, like CPUs, GPUs, RAM, tools, and lighting, overwhelmed console hardware when loaded all at once. To solve this, we built the functionality for the asynchronous scene and details upload that loads parts of the workshop and PC components in the background. The system processes objects in small batches, retrieves data from lightweight duplicates, and gradually integrates full meshes, textures, and physical interactions.
Result: Players interact with PCs immediately, while the rest of the workshop loads in the background.
/ Phase 4 /
Delivering true-to-life graphics for every PC part
Console builds showed visual artifacts, like shader glitches or overexposed areas on PC components, which negatively affected the players’ immersion. We tracked down the problem areas on each console build and added the missing shader code.
Result: CPUs, motherboards, cables, and other PC parts look realistic on PS4, Xbox One, and Switch.
/ Phase 5 /
Making in-game PC components work like real hardware
Some PC parts in the game didn’t perform like their real-life counterparts. Our QA team audited all component behaviors and flagged discrepancies between real hardware logic and in-game behavior. We shared our findings with Irregular Corporation for correction.
Result: All PC components behave like they should in reality.
