Canvas; drawing speed


I have built a windows with canvas where I draw 128 x 128 cells with text in Xojo.
The same I have done for Chrome with JavaScript.

Where Xojo get CPU over 25% redrawing in Paint event, Chrome stays below 3%.

I assume that Chrome uses the graphics acceleration of a graphic device and Xojo does not, correct?

Please, forgive me that somewhat general compare here.
Also, I have checked all settings for canvas control before.

Xojo draws the cells fast, but resizing window or mouse moves cost time (200ms) where Google Chrome does not seem “to do anything” at all (<10ms).

Or do I have to use OpenGL or anything else?

At least, canvas is still a full control.

Thanks for any hint,

Post your drawing code. perhaps someone can help you optimize it
