RTAI patches the kernel with an interrupt pipeline and handler that can take over real time interrupts but drivers can still interfere with it.
Things used to be worse. Especially with integrated GPU's. We did lots of RTAI development over the past few years and we had difficulty building custom RTAI kernels with jitter (measured using only the latency test) <5uS on AMD APU's (with integrated GPU's) made in the past 5 years. 5+ years ago people were having problems with boards with integrated graphics. Getting them under 100k uS was not possible without using an external GPU card. We didn't touch any nvidia or Intel silicon but most AMD boards were under 25uS with integrated graphics.
