MEMORANDUM
The “Better Together” Trick (Hybrid Setup)
You don’t have to choose for the entire system. With two or more GPUs: tcc wddm better
WDDM 3.2+ Enhanced TDR (Timeout Detection and Recovery): Implement more granular TDR controls to prevent "Display driver stopped responding" errors during long-running AI kernels without needing to switch to TCC mode entirely. TCC: Common in server/HPC; can be simpler and
TCC vs. WDDM: Why TCC Mode Is Better for High-Performance Compute TCC: Common in server/HPC
WDDM is the default mode for almost all consumer GPUs because it is required for anything you see on a screen.
- TCC: Common in server/HPC; can be simpler and stable for exclusive GPU compute use.
- WDDM: Better for mixed desktop/compute workloads and consumer systems.
3. How TCC Solves That Problem
TCC mode tosses out the WDDM baggage. Here is exactly what TCC does differently—and why it’s better.
