It seems to be dependant on drivers - my laptop has a GeForce4 440 Go which used to be very slow when using Text over 3D in either mode. But recent I upgraded the drivers and now Text is fine in windowed mode but still really slow in full screen. Whereas my other PC has an Intel gfx thingy and it's fine with Text in either mode.
Basically I'd avoid using Text for "real" display purposes as you just don't know how it's gonna react - even different version of drivers for the same card handle it differently. I only use it now for non-time-critical debug info.
