- Ludeon Studios announced an unstable 1.7 beta on October 12, transitioning to the new custom Waylith Engine with reported 2-4x performance gains.
- Securing the PC base game for under €20 allows users to test hardware compatibility, avoiding the standard official cost.
- Existing saves remain fully compatible, though PCs older than a decade may face new hardware risks during this testing phase.
While RimWorld sustains a massive active community following the 1.5 Anomaly update, the October 12 announcement of the 1.7 unstable beta branch introduces a critical hardware shift.
Older PCs might struggle as the game officially departs from Unity. This makes a discounted entry point the safest way to test compatibility.
Is Your PC Ready for RimWorld's New 1.7 Engine Update?
Players with desktop rigs built over a decade ago are the most likely to experience compatibility issues with the 1.7 beta.
Because testing the new architecture requires base game ownership, securing a discounted key is the most logical way to check performance without absorbing retail markups.
The move away from Unity fundamentally alters how the game interacts with older processors.
Accessing the unstable beta branch requires a legitimate copy of the base game, but there is no need to pay standard store prices just to verify your hardware limits.
Acquiring the game for under €20 provides a financially sound, low-risk method to test the experimental branch.

What Performance Gains Can Players Expect in the Unstable Beta?
Players testing the unstable 1.7 branch can expect potential performance gains of 2x to 4x late-game speed. This is primarily driven by the custom Waylith Engine replacing Unity.
While existing save files carry over seamlessly, this remains an experimental build, meaning localized bugs and stability issues are expected.
The studio's internal metrics highlight significant improvements in tick rates for massive colonies, with load times for 1,500-mod setups dropping from 14 minutes down to 6 minutes.
However, because this is not a guaranteed stable release, performance will vary based on individual system configurations.
| Feature / Aspect | Current Unity Engine (Stable) | Custom Engine (1.7 Beta) |
|---|---|---|
| Performance | Standard baseline, slows late-game | Reported 2-4x speed increase |
| Save Compatibility | Fully stable | Fully compatible (Unstable branch) |
| Hardware Risk (10+ Yrs) | Low (Well-documented limits) | Moderate to High |
Final Verdict: Should You Buy RimWorld Now or Wait?
New players should secure the base game now at a discount to evaluate hardware performance on the 1.7 beta before purchasing additional expansions.
Existing owners should simply opt into the Steam beta branch without repurchasing, as their current license grants full access to the update.
Testing compatibility early ensures your system can handle the custom engine without risking the higher upfront cost of bundling DLCs like Biotech or Ideology.
