General :: MT6589 With 1080p Screen - 3D Game Lags?

so I got this phone, mediatek MT6589 1,2ghz with 1080x1920 resolution display, GPU powerVR SGX544 (those are what it says on the spec)

when playing 2D games, there are no lags, stutterings, i got smooth animations and responsive controls.

but when trying to play 3D based games, i only got like 5-10 fps, even for low end games like asphalt 6, riptide 1, minion rush, etc.

some 3D games have the option to lower textures, effects, shaders, but some don't.What I'm trying to ask is :

- Can we tweak, modify build.prop to trick those games (that do not have quality settings in options) to load low quality graphics? If we can, which line?

- I tried to install "resolution changer lite" from the playstore, looks like when I change resolution to 1024x600, every games run smooth without lag. But this resolution changing really messed up my homescreen, icons, menus, even hardware buttons don't work.

FYI: for reference this device's antutu score is 12000+, 2d score= 600, 3d score = 2100
