A lot of older IMGTec devices grabbed a large chunk of memory upon initialization which other things couldn't touch, even if the GPU wasn't using much of that reserved space at all.
On Jetson platform maybe. But on Nvidia Shield Tablet many software report me 224 MB max. If the report is wrong where they take this information ? That the same thing on Nexus 9 ?
Exemple : My phone Galaxy S3 report 102 MB Gpu memory(2 GB ram)

Certains games work better with a reduced resolution(480p)(SSBM, Wind Waker, etc) which make sense with limited gpu memory.

memory isn't limited. The reported values are based on temporary allocation. Those are not constants. As soon as you demand more than what is available, the allocation will be increased, as long as it doesn't interfere with android's used memory (not including cached apps and other throwaway usage). The reduced resolution is because those games are GPU heavy and reducing the resolution is producing the natural performance increase. It's not a memory issue. Dolphin has never been a terribly large memory user.

this statement is why i think 0.5 resolution is needed. increase in performance making more games playable at full speed.
