Hi. I am a complete Orbiter newbie and any help would be greatly appreciated. I am getting both lockups and/or CTD when trying to launch some scenarios, while other scenarios launch just fine.
Examples of scenarios that fail are Checklist/Mission 1 and DeltaGliderIV/Earth/Flyby at KCS; examples that work fine are
Delta-Glider/Brighton Beach and DeltaGliderIV/Docked to MIR. Failure or success is consistent; if the scenario fails it fails every time, and if it succeeds it succeeds every time (after many repeated attempts).
For the failing scenarios, when using vanilla Orbiter the program locks up with no error message; the system must be restarted (not even Task Manager will kill the program). When using D3D9, it is a CTD instead of lockup. It is the same scenarios that crash for both vanilla Orbiter and D3D9.
Looking at the logs (verbose on), the last entry is 000000.010: Texture load: .\Textures\Earth\Cloud\05\000000\000001.dds, so perhaps it is failing to extract a texture? I have tried replacing the default textures with some hires textures, but the failure persists. I have also tried disabling Clouds in the visual options, but that didn't help. I have tried re-downloading and re-installing Orbiter (both zip and exe formats); MD5 checksums on the downloads are good.
Running Windows 11 (latest patches), 16 GB RAM, AMD Ryzen 5 2600 CPU, NVIDIA GTX 1050 Ti (latest drivers) with 4G, screen resolution 1920x1080 @60 Hz.
Any suggestions? Thanks in advance.
Mike.
