Nvidia probably doesn't want to fully disable the last .5 GB due to legal implications at this point. All they seem to do is use a blacklist for all games that will use more than 3.5 and show stuttering and limit the vram use below the threshold.
This "blacklist" and limit vram to 3.5 GB makes absolutely no sense at all.
If the game does not require more than 3.5 GB then the 970 runs it just fine.
If the game REQUIRES more than 3.5 GB then not using the extra 0.5 GB will actually make the game stutter MORE because the game will have to go to main memory which is even slower than the 0.5 GB segment.
