<p>Jcromartie: /* DF Doesn't Need a Fancy GPU */</p> <hr /> <div>== DF Doesn't Need a Fancy GPU ==<br /> <br /> Even considering how DF uses OpenGL for graphics, an integrated card should have absolutely no problem displaying 2000 quads on screen.<br /> <br /> I threw together a quick and dirty test app to render 2000 dwarf faces, and it can manage 100 FPS with just 18% CPU load. Without throttling I get 600 FPS with 80% CPU. That's on an integrated (GMA x3100) card. So, at least for Intel's GMA cards going back at least two years, the graphics should perform just fine.<br /> <br /> So that's why I don't think it should be necessary to recommend a powerful discrete GPU, especially when the screen isn't updated very often.<br /> <br /> --[[User:Jcromartie|Jcromartie]] 13:31, 9 May 2008 (EDT)<br /> <br /> == General Performance ==<br /> <br /> I may be talking out of my butt here, and as a developer I can understand the challenges of (and reasons to avoid) optimization, but might it be time to start tuning DF? It uses 99% CPU on a 2.2GHz Core 2 Duo ''all the time''. This is even the case when displaying the main menu or when paused.<br /> <br /> Maybe [http://www.artima.com/cppsource/how_to_go_slow.html this article] can shed some light on why it uses so much CPU when it doesn't need to?<br /> <br /> --[[User:Jcromartie|Jcromartie]] 13:31, 9 May 2008 (EDT)</div>
