HTC has once again started rolling out a new software update for the international variant of the One X, that aims at improving the performance of the handset and fix some minor bugs. While HTC has not provided any official change-log for the update, one major change in the update is that HTC has enabled GPU Rendering by default on the handset.
For some strange reason, HTC had disabled GPU rendering by default on the One X previous to the 1.29 software update. Considering GPU rendering is one of the biggest under-the-hood changes in Ice Cream Sandwich, HTC really had to be insane to disable it. The company only allowed GPU acceleration in certain applications including some from Google and a few benchmarking apps. Otherwise, only those apps that specifically enabled GPU rendering in their manifest.xml were harnessing the power of the GPU instead of the CPU. There was no way to force GPU acceleration on all applications, like it is on the Galaxy Nexus and other Ice Cream Sandwich running handsets.
Thankfully, HTC has fixed this issue in the 1.29 software update. Some One X owners also suggest that the update brings about a slight improvement in the battery life of the handset as well.
