Ray Proudfoot Posted September 20, 2021 Share Posted September 20, 2021 I’m posting this here even though I don’t currently have any 64-bit FSL aircraft. There was a post a few months back that helped but I couldn’t post on it as it had been locked. Here’s what I did. Forgive the reference to PMDG This morning's test flight from KLAX to KSEA might be significant. For the first time since these DXGI errors started this has been a troublesome route but I was able to fly it without incident. Other flights up to CYVR use the same routing I've not been able to complete in the PMDG without the DXGI_DEVICE_HUNG error. What changes? Well the 'Prefer Max Performance' is still set in NCP and I still have TdrDelay=0 in the Registry. The only change was clearing out DirectX Shader Cache yesterday. I'm going to clear it out after each flight as part of this testing routine. Whether retaining them is significant will only become apparent after several successful flights - should that happen. I’ve now completed two troublesome flights without a problem. I suspect I had one or more corrupted DirectX Shader files and deleting them has fixed what was an annoying problem. Hope this helps anyone else having this problem. DirectX Shaders can only be deleted via the Disk Cleanup process as described here.. https://youtu.be/vAnvZjdRjoU 2 1 Quote Link to comment
