The problem I was mentioning might be more obviously visible in the attached night textures. Or is this just the DX10 incompatibility of this scenery?
When a scenery is not compatible with DX10, most of the problems happens at night, it's really difficult to troubleshoot this considering the fact you use the DX10 fixer, which in any case says that not all sceneries can be fixed, especially those that have problems at night. So, basically, consider Zurich to be usable in DX9 only, until we'll do a major update like JFK V2.
