Most people probably are not aware of this issue and rightfully so don't care as they are not affected. At the same time, as I happen to have the T-Mobile version of this phone, I stumbled upon this issue:
Problem: Our Kaisers currently lack proper D3D (direct 3d) drivers and are therefore performing at a fraction of their actual capabilities. This results in poor video playback, poor camera/image performance, and bad performance in video games and other video-intensive software.
Although owners of this phone-series have been pleading with HTC for driver updates, it doesn't seem like HTC really cares or wants to offer drivers. Their solution is to wait for future hardware and to buy it when it becomes available. Nice response, ya think?
Anyhow, on the site XDA Developers, a bunch of owners have ponied up money to solve the problem themselves. Anyone who is able to create the necessary driver can score more than $5000, growing daily. Users on the site are pledging money as we speak to increase the bounty for whoever manages to create this fix. If it is created, I am game. I love the idea of resolving an issue this way. Screw HTC for not stepping up to the plate to offer a resolution.
