Refer from Adam, Nathan’ WPF unleashed for 3.5.

  • -> static property Tier and TierChanged event

Tier is 32bit int number, however, the real value is stored in the higher 16 bytes.

int tier = RenderCapability.Tire>>16;

if tier == 0, system will use software rendering;

if tier == 1, system will use hardware rendering sometimes;

if tier == 2 [highest level], system will use hardware rendering, wherever graphic could be rendered by hardware.

-> esp. in tier == 0 system, will be difficult to run multi-animation[with 3D effect or complicated transition] .

  • So how-to for tier == 0 system, 1, remove Animation; 2, eliminate DesiredFrameRate of Storybard[normal case = 60frames/second],
