It's likely that something else has attached itself to the trainer that is using the GPU.
If this is true, how would I go about verifying if this is true?
Also I've only used 4 trainers so far and it seems that I only have this issue with the Civilization 6 trainer and not the others.

Every trainer is unique and uses different methods, even though they "look" the same or similar.
