This issue is with SEHS. It used to run well on TSW 2 but I find that I’m not picking this route anymore as it’s such a letdown. The shadow draw on the tracks and trees along with the miles of flickering fences makes this a lot less fun to play. Also there’s the dropping FPS, particularly noticeable at Ashford. What’s strange is older routes like Bakerloo and GWR run so smoothly and look great. Please DTG fix the shadow draw or at least add an option to switch it off.
