Honestly, we dont have a solution for you. And its not a bug, its just hardware/software difference. All players have different experiences with that area in the game. Some have lags, others get crashes, others have no problems at all. Its not something I can 'fix' since its not an issue with the game, its an issue with your individual computers. If updating your driver doesnt work, or allocating more space to your graphics memory doesnt work, or simply running the game on recommended Driver settings doesnt work, i have nothing for you. Sorry m8, I'm just a dev, not a software engineer or computer science expert.
