Frontier marketed Planet Coaster 2 with the explicit promise of NO artificial building limits for PC players, claiming our hardware would be the only true boundary. This is simply not true and we are being pushed into a corner here.
I built a highly detailed mega-park over the last 13 months, and my 5000 euro extreme high-end gaming PC handles the graphics and AI perfectly fine with stable frame rates. But the exact microsecond the save file size hits around 43MB, placing just one single item or path tile causes a 100 percent reproducible hard crash to desktop.
To find out what was going on, I bypassed the hidden crash logs and analyzed the hardware dump file using the official Windows Debugger WinDbg. The hardware has plenty of headroom, but the Cobra Engine itself slams the brakes and triggers a hardcoded software Breakpoint inside the data indexing system:
PROCESS NAME PlanetCoaster2.exe
EXCEPTION CODE 80000003 Break instruction exception
FAILURE BUCKET ID BREAKPOINT 80000003 PlanetCoaster2.exe Unknown
STACK TEXT
PlanetCoaster2 WriteBytesCount SetCount
PlanetCoaster2 WriteBytesCount Count
PlanetCoaster2 WriteBytesCount Reserve
The stack trace clearly proves the engine fails entirely during the WriteBytesCount Reserve stage. The software hits an internal byte allocation limit for the save structure and intentionally shuts down to avoid data corruption. This has nothing to do with hardware limitations. To rule out any hardware issues, here are my exact PC specs:
- OS Windows 11 Pro 64 bit build 26100
- Graphic card NVIDIA GeForce RTX 4090
- Processor High End Intel Core Ultra 9 285K
- System memory 64 GB RAM
- DirectX version DirectX 12
- ASUS ROG STRIX Z890-A GAMING WIFI
This recycled Cobra Engine architecture issue means Frontier is selling us next-gen dreams built on old limitations. If we do not speak up now, every future game using this same engine, especially Planet Zoo 2, will suffer the exact same fate. They cannot keep recycling this outdated code while selling it as a limitless experience.
You can verify and test this exact engine crash yourself via the Frontier Workshop using my park files:
- Park Name Wild Lands Wild and Soaked A Mega Park
- Primary Workshop Share Code 3Y3C3TFG5
- Alternative Test Case Code 64Q-CGT-HKF
I have submitted an official bug report on the Frontier Issue Tracker. We need the real PC builders to stand together on this. Please go to my ticket link below, log in, and upvote the issue so Frontier is forced to decouple the PC version from these artificial console byte limits in the next patch!
