Hello everyone, I am facing problems using Path Tracing in UE4.27.
After I render some frames sequencer, closing the Editor gives this crash:
Unhandled Exception: EXCEPTION_ACCESS_VIOLATION 0x0000020d9f821460
Processor AMD Ryzen Threadripper PRO 3975WX 32-Cores 3.50 GHz
Installed RAM 64.0 GB (63.8 GB usable)
System type 64-bit operating system, x64-based processor
Windows 10 Pro
Nvidia Geforce RTX 2080 SUPER
I have tried the following:
- Changed the NVIDIA driver version, tested with Standard (462.59, 471.68, 472.12, 472.39, 472.47), with or without Geforce Experience, also tried with DCH driver version (don’t know what DCH means) v.497.09 without Geforce Experience.
- Added Timeout Detection & Recovery (TDR) in Registry Editor to 60
- I have downloaded mpo_disable.reg from NVIDIA Website
None of the steps above helped.
I was working with Path Tracing and it was fine using my previous Intel computer.
