Train Sim Classic will not launch through Steam. It did work in August because I remember playing Saluda at launch. Upon launch, I seem to immediately have a graphics crash (black screen, Windows disconnect sound, Explorer.exe seems to relaunch) and is stuck on a Window: Error: Failed to creater vertex Buffer (D3RERR_INVALIDCALL). Happens with 64, 32 bits and DX12 experimental. Steam file check and repair did nothing, removing and reinstalling did not. I did a fresh Windows reinstall, installed my drivers and immediately installed Steam and TSC, same issue. Specs: Windows 10 Pro 21H2 Lenovo Legion 5 laptop i7-10750H, 16 GB ram RTX 2060 mobile 6GB Vram + Intel discrete graphics Nvidia game ready driver 546.33 Tried GPU settings (which GPU to run the game on) on auto, and forced Railworks64.exe on the RTX, no success. Edit: No external mods, only Base game + Steam DLC.
No mods installed, just vanilla game + Steam DLC. However, after digging through Windows Event Viewer, I found something that lead me to fix the problem. Issue was, I was using a monitor connector to a USB 3.0 Dock with DisplayLink. The game was crashing my dock somehow. I tried updating my dock's driver from the manufacturer's website, same result. For reference, the error was: Event ID 10111, DriverFrameworks-UserMode The device ThinkPad USB 3.0 Pro Dock (location 0000.0014.0000.021.001.000.000.000.000) is offline due to a user-mode driver crash. After removing the dock and connecting my monitor directly on my laptop, the game boots fine. I've been using the dock for roughly 2 years, no issue with any game but TSC. Last time I played, I had relocated my computer temporarily for some renos in my office, and was not using the dock for a few days where I played TSC.
