Ah good point. If it was just affecting Nvidia cards then a driver update would be all that they need.
This is sounding more like a software issue on the Call of Duty side then.
But DLSS does still get updated models with driver updates:
DLSS uses the power of NVIDIA’s supercomputers to train and regularly improve its AI model. The latest models are delivered to your GeForce RTX PC through Game Ready Drivers.
Thanks! I definitely need to upgrade from the starter ship.
