I have a radeon hd4250 and running 2 monitors. I have everything set pretty low, if not off in the game settings, including advanced settings. I play the game in 1024x768 window(not full screen). My frame rate varies from decent to very bad, depending on my f.o.v. I've pretty much given up on building large ships or anything big, for that matter. Just having a space station in my field of view makes movement clunky. The game is awesome enough that this is not a deal breaker, but the ability build something and have it not cripple game play would be nice. I have 2 ships are carriers that probably will never see completion because they've become to much of a chore to move around and place blocks. ...and judging by awesome and inspiring screenshots others have uploaded. my ships are big, but not nearly as big as many I have seen. I remind myself that the game is in alpha. I just hope they find a work around later on. I'm a Linux user as well, and as such this, game is a godsend. Thanks devs. This games scope also makes the decision of maybe having to buy a different video-card an easy choice. although a fix would be better. ...um, I gotta get back.
