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.
This is starting to tick me off. Now you’ve got me all wound up!
