Mid-game shader compilation freezes + GPU device removal on DX12 — RTX 5070 Laptop (with logs)

Issue 1: GPU Device Removal (black screen)

Screen goes black mid-session for a few seconds then recovers. Found this in Client.txt:

[CRIT] [D3D12] Device Removed. Reason: 0x887a0005
[INFO] [RENDER] Render Device was removed - DeviceStart jobs: 16090 frames ago
[INFO] [RENDER] Restarting device


0x887a0005 = DXGI_ERROR_DEVICE_REMOVED - Windows TDR killed and restarted GPU driver.

Partial fix found: Enabling in-game FPS limiter eliminated the black screen entirely. Suggests GPU is hitting a load spike during shader compilation that triggers TDR. FPS limit reduces baseline GPU load enough to survive the spike.

Issue 2: Mid-game shader compilation hitches (still present after FPS fix)

After initial ~6000 shader batch on first launch, game continues compiling small batches (2-10 shaders) during gameplay. Each batch causes a visible freeze.

From in-game performance overlay during freeze:


GPU sitting idle at 2ms while CPU blocked at 312ms. Render thread stalled on PSO compilation.

engine_multithreading_mode=enabled is already set in config - issue is DX12 blocking render thread during runtime PSO compilation.

Happy to provide full Client.txt if helpful.

Turns out i had installed on SSHD and i was thinking i have on my nvmi ssd... womp womp...
