before doing this I could run it on the but was really laggy and the game was unplayable on the T.
Things you will need;
Now you need to install gltools and install the 2nd driver.( on the play store but its paid, no warez here so no links)
Now open gl tools and find pokemon go.
Check force 16 bit rendering and optimise glsl shaders. Next set render resolution to 0.5 (doesn't effect a whole load but helped with the Ts 720 screen, probably not needed for lower res) and set downscale textures to 0.5. That's it done!
After doing this, the game runs butter smooth on my T and runs somewhat smoother on my M. This is all because the app uses less ram (was hitting nearly 600mb ram at most)
Let me know if it helped
