i play in VR and was looking forward to the spark fix as previously it was set at the wrong 3d depth. Now I don't get them at all? My Particle effects setting isn't working and is set to "off" no matter what setting I use. I get exhaust flames, I get gravel kicked up by wheels and I get smoke, but I don't get trailing water vapor clouds behind cars and neither do I get the the new spark effects from the underside of race cars. I've deleted the game folder and reinstalled. Deleted My Documents game folder and deleted Steam Users folder. Still no change. My system is RTX 4090, i9 13900KF, 128GB DDR5 5200. Windows 11 Home. Varjo Aero VR headset. Everything is up to date. Any ideas?
