I'm trying to work out why you get micro stutters on some routes but not others. If I run a RSSLO route I'm getting micro stutters at certain places on the route but when I run a DTG route it runs smoothly without any problems. Same with some of the other European routes where it runs ok. Berlin - Leipzig, Ringbahn Berlin, Koblenz - Trier have no problems - just RSSLO routes
I think it also depends on the age of the RSSLO route. Their early ones have better frame rates and less micro-stutters. I currently only have the Allgaubahn installed, but it stutters no more than anything else, and that's very little.
Poor optimisation on RSSLOs behalf. Very large asset blocks, no low poly distant vegetation etc etc….
