So, you have issues with playing games huh?! Probably you are having a budget smartphone or tablet that can’t really support high-end games like Real Racing 3, NBA 2k14, Dead Trigger, etc. Fortunately, android developers heard your problems and develop an app capable of making lower-end android device feel the high-end gaming experience.Let me introduce GLTools , an app that allows customization of resolution and graphics rendering of apps for optimizing gaming experience. With GLTools , it will allow you to play games which actually requires higher specs or rather play games with lesser lags and FC (force close). If you are familiar with what this app can do, it might be you have heard of Chainfire3D, but, this one supports any android versions starting from android 2.2 and above with lesser issues.
What is GL Tools?
GLTools is a custom OpenGLES driver (proxy), that is compatible with any known OpenGLES 2.0-compatible GPU + ARM or x86 processor. If you still don’t understand, what this app is, the closest known analog is Chainfire3D.

How to Install GL Tools in low end Android device
Step 1 . Download and install GLTools . Download the Free Version. or Paid Version .

Step 4 . Check Enable custom settings for this Here’s the tweaking part
Step 5 . Check Force 16 bit rendering . (it reduces lighting and shading effects but not much a biggie in the graphics)
Step 6 . Check Optimize GLSL shaders. (for optimizing OpenGL shading responsible for color, texture, structure)
Step 7 . Enable and set Downscale texture as what you like. (It reduces the texture therefore, lesser lag)
Step 8 . You may want to Use fake GPU info. (Can also improve game graphics quality and performance)
Step 9 . Now, it’s done. Play any games you wanted.
