What are your experiences overclocking PICs?
Out of curiosity I changed the crystal for PIC 18f24j10 to 12.28 MHz (4x PLL = 49.12 MHz). Specification is 40 MHz max.
It causes a considerable increase in display refresh speed, especially using fonts including to set all the background pixels.
There are other means to improve speed:
-To write the text again in the background color
-To store pixel values in a points list, and restore later (mind the small RAM on some PICs).
-To prepare bitmap in memory then use optimized code to write it to LCD as bitmap
