Slow 3D performance on your HTC HD2? Poor video performance too? No worry, XDA Moderator, Chainfire created a HD2/Leo 3D Driver Patch for all of us. I did install version 1.1 before forgot install it back after ROM upgrade. So far I don’t have issue with games on original stock driver because I am not a hardcore gamer on mobile phone but desktop. In short, HD2/Leo 3D Driver Patch is a hack to HTC HD2 3D driver. It will improve HTC HD2 3D performance a lot.
