The tablet
Prestigio MultiPad PMP7170B3G(MT6575, PowerVR SGX531). I installed the program, installed the driver with the Default plugin. Adjusted the reduction in texture resolution for the game AVP Evolution. It helped, the game stopped crashing (before that, apparently, there was not enough memory for textures). However, after installing the driver, almost all previously launched games that have a splash screen with some video in the introduction (Assasins's Creed: Pirates, Bounty Arms, NFS: Shift, etc.) stopped running. At the moment when the video should be shown, a black screen appears and the game hangs (or hangs during the download process). This happened even with those games whose profile was not corrected in GLTools. In addition, in the game Assasins's Creed: Pirates, a strong blurring of the image was observed when trying to turn on the FPS counter. After the demolition of the driver through the recovery game began to run the same way as before. I tried to install the driver without a plugin, the effect was the same.
