Ashes of Singularity - Escalation (v2.3 latest) - when SMT mode is enabled in the BIOS, the DX12 benchmark crashes to the desktop (after running for a bit), DX11 mode is unaffected. If I disable SMT mode on the BIOS, the DX12 benchmark completes just fine without issues.
CPU: RYZEN 7 1700X
Motherboard: Asrock Taichi X370 (with V2.4 UEFI) - also happened on my Gigabyte AB350-GAMING 3.
Memory: 32GB DDR4 (2133 MT/s)
GPU: EVGA GTX1080TI (also happens on GTX1070 FE)
OS: Windows 10 x64 (OS BUILD 15063.413) - running AMD Chipset 17.10 drivers and the Ryzen Balanced Power Plan
Steps to Reproduce:
1) Execute Ashes of Singularity - Escalation
2) In Video Settings, make sure it's using DX12 mode then Restart
3) Try running the built-in benchmark using "GPU Focus" Scenario. Make sure it says DX12 model, and that 16 logical processors are listed in the CPU section.
4) Run benchmark.
Application Crashes to Desktop consistently when SMT is enabled.
Cleanly installed windows, ran Intel Burn Test, Memtest86, Prime95 stress test for 8 hours without any issues. Tried both Gigabyte AB350 Gaming 3, and my current board (after clean reinstall) but the problem keeps occurring when SMT mode is enabled.
