Steam Tsw 7 – Black Flickering Parts Of The Map + Persistent Fps Drop Approaching Stuttgart Hbf

Hi everyone,

I've been having two annoying performance/graphics issues in TSW 7 and wanted to see if anyone else has experienced something similar.

1. Black flickering parts of the map

Sometimes parts of the scenery start flickering black. It's not the entire screen going black, but individual chunks of the map, for example parts of the tracks, platforms or surrounding scenery. They flicker rapidly and make the game look pretty broken.

I was using DirectX 12 when this happened. After switching to DirectX 11, the issue seems to have gone away, although I can't say for certain that it's completely fixed yet.

2. Persistent FPS drop approaching Stuttgart Hbf

This one happens around Stuttgart Hbf when driving the 2018 timetable, which has quite a lot of rolling stock around the station.

Normally, if I get an FPS drop, it only lasts a second or two. However, sometimes when approaching Stuttgart, the FPS suddenly drops and seems to get locked at a much lower level. It stays like that for a while instead of recovering normally.

What I've noticed is that my GPU usage is usually around 55%, but when this happens, it jumps to around 95–100%. After some time, the performance eventually recovers. I haven't tested whether Alt+Tab fixes it, so I don't know if that makes a difference.

I'm not sure whether this is caused by the amount of AI traffic, the graphics engine, memory usage or something else.

My PC specs:

• CPU: AMD Ryzen 5 5600
  
  
• GPU: NVIDIA RTX 3060 Ti 8 GB
  
  
• RAM: 16 GB
  
  
• Resolution: 1920 × 1080
  
  
• Graphics settings: High
  
  
• Graphics API: DirectX 11 currently (switched from DX12 because of the flickering)
  

Has anyone else experienced either of these issues, especially the persistent FPS drop around Stuttgart Hbf? I'm also interested to know whether switching to DX11 has helped anyone else with the black scenery flickering.

Thanks!
