Question: Where is text rendered? on the gpu or cpu?

That depends on a lot of factors but regardless even if it's ultimately rendered on the GPU it's first generated on the CPU as in glyphs are rendered and put in a glyph cache. Those might be cached in textures and then used to render text with the GPU as appropriate.

That depends on the browser renderer. However, I suppose most windows browsers use Direct2D for 2D rendering, which is Microsoft's 2D API for the GPU.
