I just recently got a new laptop and it has an Intel HD Media Accelerator, which is obviously integrated. On my desktop, I have an ATI RADEON 850. With Blockland on my laptop, I experience intermittent spikes of lag that last for anywhere from 2-5 seconds. Sometimes, they last so long that Blockland crashes. I've never experienced this problem on my desktop. It would be great if version 17 could include improved support for integrated graphics cards, however one would go about doing that (if it's even possible).
