HTC TyTN II
smartphone model
The HTC TyTN II (also known as the HTC Kaiser, the HTC P4550, and the HTC 8925) is an Internet-enabled Windows Mobile Pocket PC smartphone designed and marketed by HTC Corporation of Taiwan. It has a tilting touchscreen with a right-side slide-out QWERTY keyboard. The TyTN II's functions include those of a camera phone and a portable media player in addition to text messaging and multimedia messaging. It also offers Internet services including e-mail, instant messaging, web browsing, and local Wi-Fi connectivity. It is a quad-band GSM phone with GPRS, EDGE, UMTS, HSDPA, and HSUPA.
Video driver issues
Soon after its release to market, reviewers and end users reported the TyTN II's graphical performance was below par. Both 2D and 3D graphics were affected, with notable symptoms being poor video playback and severely low frame-rates when running 3D applications and games. The hardware platform (Qualcomm 7200 chipset) suggested that the device was capable of high graphical performance, however the device was consistently outperformed by older HTC devices.
A community of enthusiast developers investigated the cause of the poor performance and concluded that DirectDraw and Direct3D applications were running in software rendering mode only. No hardware acceleration was taking place, and the drivers required to take advantage of the ATI Imageon hardware appeared to be missing.
Many users within the community were dissatisfied by the apparent omission of a video driver that would allow hardware acceleration of graphics, particularly since the device included rendering hardware which was not being used.
