You may have other issues going on, so a video emulator might not be the "cure" you're looking for. But my understanding is that when there's no monitor attached to the Mini, the GPU doesn't get activated. The result is that the graphical elements of OS X such as OpenGL revert to being emulated in software. Also, there's a big difference in accessing such a machine via ARD because without the GPU, the CPU is doing all the screen rendering, causing a lot of lag.
