Short and simple, GfxBoost activates “QTV” mode for specific surfaces. This makes for example DirectDraw display smoother and: a bit slower or significantly faster, depending on how you look at it. It also seems to have a small effect on Direct3D/OpenGL.

For HTC-built MSM7K-based devices only! All MSM7K are technically capable, but only HTC’s may have the correct drivers. Will probably not work on stock ROMs.

Changes:

– Some changes to fix issue of GfxBoost not showing up in control panel for some users
– Slight adjustment to loader code, hopefully works for more peoples now (always a guess, if not you can always use 0.7)
