OK so we don't even use half of the 512 ram at the moment.
When we get the update to utilize more RAM

Will this improve 3D game performance...most games run fine but demanding games such as Toonwarz can get sluggish at times. Or is this just limitations of the snapdragon?

just an FYI
I use advance task manager and i kill task before playing demanding games im around 100mb free when i start playing..
