Why my GTX980ti Hybrid is only using 3.9 MB of 6GB?

Play BO3, can easily get 5500mb's on 1080. Prolly more with "that" card.

Yea but BO3 just caches as much information to the VRAM without having a huge impact on performance just like ROTR.

 

390X and 980 somewhat similar in performance despite the 980 having only 4GB.

"It seems as though Crystal Dynamics' engine will happily use as much VRAM as it can, but is very well optimized to make do with much less without sacrificing framerates."

Yea but he doesn't care. He wants it all used. 3.9mb's just isn't a enough.
