On user reported that for him this change didn’t made much difference and what made difference is removing LightTankExperimentalTracks from the level. It is performance heavy but not that heavy, perhaps there is something wrong with it in another aspect. For now, I’ll remove it from the level. Could you try doing the same?
Basically I should get rid of current way of how you get into vehicles. Was planning to have something like a spawner platform, where you can select a vehicle to spawn and then posses it to drive around. Just to avoid having all this vehicles in the level. especially as only few of them have ability to go into “sleep” state when inactive.
