So I made some code using dynamic font without NGUI.
It worked well on LG optimus LTE.
But It didn't worked well with UILabel of NGUI.
In case of SKY Vega racer it didn't worked well like LG optimus LTE.
I found out that the cpus of those devices are made by qualcomm.
Qualcomm Snapdragon S4 Plus MSM8960
Qualcomm MSM8260
They all use adreno GPU.
It seems that NGUI dynamic font is not rendered well on the mobile device which has adreno GPU.
How can I start to modify the code ?
