Particles vanish at high speeds/when close to camera

As of a week ago or so (Maybe less), particles seem to flicker out of existence at higher speeds in-game. In Vehicle Simulator, we use flames for nitrous effects. When the player goes above 300sps, the particles vanish/flicker in and out.

  3. Spawn a car in
  4. Open autoshop, go to modifications, select nitrous.
  5. Equip any nitrous bottle.
  6. Exit autoshop
  7. Activate nitrous using shift key, then go up to 300mph+ in-game. Zoom in close to bumper of car. Particles will vanish/flicker in and out.

Don’t know if this is just on Vehicle SImulator, due to the fact that whenever the flashes occur in-game the game itself also seems to do a quick flash looking like a quick lag spike a long with the particle flicker.

Hi @Belzebass, it looks like this was a regression caused by a recent optimization to particles. We’ve reverted the change so it should hopefully be fixed now.
