Is there any evidence Nvidia cripples performance on old GPU

I have read a few articles on this that said no. But this week I was trying to get Forza 6 Apex running without hiccups and micro-stutter on main rig (see sig). Eventually determined it would play smoothly at 1080p but only with AA disabled and vsync off. Aliasing is pretty ugly on a 27" 1080p monitor, and the tearing is noticeable.

Next I tried Forza on laptop (Core i7 6820k, 32 gb ram, nvidia 970m 3 gb). Set to high and dynamic it ran great. The 970m is a newer chipset but a weaker gpu vs the gtx 780 (Maxwell vs Kepler). Also, this is a MSI laptop with gsync so the tearing was completely gone. In short, a superior gameplay experience on the less powerful laptop.No, there is no evidence. Nvidia doesn't seem to cripple performance on old cards so much as they simply don't spend the same time and effort optimizing them as they do their current cards. You also don't get "magical" extra performance out of the cards a few months after launch like you do from AMD cards.

Please Help.

Thanks !

I didn't find the right solution from the internet.
