So, The VRAM bug. For me flights after a fresh start of the sim from start to finish will mostly be very stable. The moment you exit a flight session back to the main menu, the next flight will be full of performance issues, Custom camera placement issues, Avatar issues etc. All of the avatar placement, bad performance and visual bugs all totally disappear after a sim restart for me. Most bugs occur for me when I try to fly a second flight or move to another aircraft etc. At the moment the only way to flush a card’s VRAM properly, is to do a quick restart of the sim before starting a new flight etc. It’s a pain, but it’s quick for me. It’s a smooth and consistent ‘almost’ bug free flight everytime. I’m then mostly just faced with specific aircraft systems bugs.
** Of course, this tip does not solve the issue of your poor internet, A major attribute to the performance and fidelity of the sim.
