I have r and rstudio downloaded on my laptop, and rstudio doesn't work properly. It's very slow. However the main problem is with the pixelation. The screen display often breaks up into different sections of pixels, making it impossible to do any sort of work.
I have a Hp Pavilion Notebook,
Processor : AMD A10 Extreme edition R8, 4C +8G 2.00 GHz
64-bit operating system, x64 based processor
