Why does the Kaspa GPU miner require different minimum driver versions per GPU?

The Kaspa GPU miner ships with precompiled PTX files tailored to specific GPU architectures, so the minimum driver version your device needs depends on which PTX file it uses. PTX (Parallel Thread Execution) is NVIDIA's low-level GPU instruction format — when the miner is built, code is pre-baked for particular hardware families and CUDA Toolkit versions. If your installed driver is older than the minimum required for your device's PTX, the miner will not run correctly. Checking the official release's minimum driver table for your specific GPU before installing saves you from a frustrating troubleshooting session.
