Is this the LCD from TechToys??

Yes, this is indeed from TechToys. They do many nice LCD modules.

Ok, but are you using the microchip library or something like that because ive never had a good refresh rate on these things.

No, All the code is written from scratch by me.
From the initialise routine to the plotting.
The key is you CAN NOT use a simple pixel plot routine.
I wrote a custom polydraw routine that does a triangle at a time. There is no single pixel plot.
The overhead of sending the x,y and colour is too big. I send the X/y for a whole line and then just pump out a line of colour. that saves many many bytes per line.
