Hi all, there are, more or less, three opportunities: Nvidia AMD/Ati Intel Nvidia has really good performance using nvidia legacy driver. You have pros and cons (I don't want to start a debate about it) of closed-source. Nvidia using nv has quite poor performance, on Linux as well. AMD/Ati platform has a lack of support on FreeBSD (TTM not fully implemented or something like that). That means no OpenGL hw acceleration. Intel is on the way: it's usable in 9-STABLE or 10-CURRENT and using not-yet-released ports. I successfully used SandyBridge with hardware acceleration, IvyBridge is still using DRISWRAST (sw raster, no OpenGL hw acceleration) and I don't understand why/no time to investigate it. If you need a solution NOW, my personal and questionable suggestion is NVidia GPU with nvidia closed-source driver. In the near future, another solution is Intel integrated graphics with open-source driver. It depends how much powerful your GPU should be. I'm using Nvidia and I have no problem. Someone had ones and it was bad, because he couldn't fix, cause closed-source nature of the driver. A note: there is a debate about x11/nvidia-driver, because it renames a couple of openGL libraries and replaces them with NVidia's ones. Using pkg (the new package system) this is not allowed. I don't know how this is could be solved. Remember also, that when you update OpenGL library (via portmaster), a cleaner way to do it is deinstall nvidia-driver, update OpenGL libraries and reinstall nvidia-driver.
