Explosions and vehicles may cause huge lag to clients with PhysX errors
Closed, ResolvedPublic


We were playing a large mission with IEDs and tanks on the map FATA. One of the tanks Drove over an IED and was somehow slung underground and to the lower left corner of the map. After the tank was flung there, every players fps went to 5-10 fps. We had to stop playing the mission due to that. RPT show many thousand lines of this:
19:56:14 Matrix is not valid as physx transform!
19:56:14 Matrix is not valid as physx transform!

This started the exact moment when the tank drove on the IED.

this error should be fixed already on the Dev Branch. However, did it happen to you with no mods enabled?

We were using RHS, and the tank was also from RHS.

I Believe that the matrix has been fixed in the current stable and this is no longer an issue. Thanks for your efforts! This ticket can be closed.
