We are switching all Roblox games to use the PGS solver on March 4th, 2019
Currently, games owners can set the Workspace property TemporaryLegacyPhysicsSolverOverride to True to use the legacy spring solver. However, on March 4th, 2019 this will no longer be the case, and all games will be switched over to the PGS solver for physics simulation.
Over the last year, we have reached out to the developer community to discuss why we are doing this and to give everyone a chance to modify their models and games so they work as desired with the PGS solver.
Please look over the following information if you still have questions or need assistance migrating your games.
- Why are we deprecating the legacy solver?
- Blog: Why you should be using the PGS solver
- LDL enhancement to PGS
- Building with PGS
Legacy Solver Users: You still have a decent chunk of time to make this transition for your games. The physics team is ready to assist. We have already collaborated with many of you to make model adjustments or utilize alternative models designed to work optimally with the PGS solver. Please take advantage of this time right now to make sure your games work with PGS. Feel free to create separate threads on the developer forum asking for help and advice (and make sure to tag Timobius).
We really appreciate everyone’s huge effort to reach the awesome level of PGS adoption we have today - approximately 98% of gameplay time uses the new PGS solver!
