Broadcom, Qualcomm, Imagination's PowerVR, Nvidia's Tegra, and ARM's Mali GPUs all have partially (mostly) closed-source drivers. In general, the only open-source code in the driver is any vendor extension to the GL and EGL header files, and a GPL'ed shim that can be loaded into the kernel to allow it to communicate with the binary-only driver. Vendors often ...

When GPU rendering was first added, it was very unreliable. Sometimes it would be slower than software rendering, and there were some kinds of GUIs that it just couldn't work with. For this reason, it was up to the app developer to test their app with GPU rendering, and set an option in the app's manifest (the same place that it declares its permissions) to ...

I'm not sure if it's part of a truly vanilla ICS build (though I think it may be), but the early CM9 and vanilla ICS builds I've played with all have a "Developer Options" entry in the main system settings. This contains several options which relate to overall graphics effects such as: Window animation scale: can be set to "off" to disable window ...

For low GPU workloads, the only sensible metric is power consumption. If the frame time is always less than 1/60 s, then changes in frame time won't affect the visual appearance of the app, so neither frame time nor FPS provide any useful information. You can't usefully measure power consumption from a user-space benchmark: you need either kernel hooks (such ...

To quote from an XDA post: Enabling this preference in developer options offloads task of rendering window components like buttons, text and complex 2d graphics calculations to GPU. This often results in much faster UI rendering including animations. On one side you will definitely achieve better frame rate (and hence smooth experience) ...

Since I cannot find any reference online to the GPU in the TM-MID777, I thought I'd post this as a general link for any model instead. Install CPU Z from the Google Play Store and run it. It will display all hardware information on your current device. This is a sample screenshot, and can be very useful if you are buying a device, or doubt that a device ...

Most modern smartphones produce a lot of heat when playing CPU/GPU intensive games, there's not much you can do about it. If you reduce GPU frequency, two things can happen: stuttering of gameplay (depending on your game), and the CPU/GPU run at maximum frequency for longer amounts of time to complete the same work (that a higher frequency GPU would have ...
