Frankfurt Koblenz Signalisation Much Broken. Dtg You Need To React On This!

ok thanks - so I keep my money

 

I've been playing on 64-bit. the signals and speed limits are a major issue. however, I'm also getting severe stuttering every couple of minutes. anyone else had this?
Cheers

I get a huge slow down in frames per second whenever it needs to load new scenery, but it doesn’t actually stutter.
