What settings would the gang recommend turning down to reduce the strain on the GPU and CPU while route building? I do my "creative" stuff on a laptop and TS sends the fans into a frenzy, such that I've been banned from using it downstairs. Don't have this issue with Trainz Surveyor and I have cleaned all the air vents, which weren't particularly clogged anyway. I was thinking possibly draw distance but suggestions welcome.
Low texture display quality, water, and shadows, reduce visibility, no adaptive bloom and no shader enhancers.
