Since using TSW3, I keep encountering massive frame rate/lag issues when other AI trains are close to me. I'm talking literally 1 frame every 5 seconds plus huge delay in the train responding to the controller but then it's fine once the train/trains are out of the way...
Same for playstation 5 poor performance all round i wish dtg would sort this out. I'm back on tsw2 at the moment at least that's smoother to play.
Wait about 6 months to a year to see whether they've been able to optimize TSW3 for consoles. In the meantime best to stick to TSW2.
