The screenshots enclosed in this article were captured off a version of Sauerbraten we built from source-code using their Subversion repository as of 2009-04-30. This should essentially be the forthcoming release of Sauerbraten but with perhaps a few more fixes and changes.
We were running Sauerbraten at 1600 x 1200 with all graphical settings within the game maxed out. Using an Intel Core i7 processor with a NVIDIA GeForce 9800GTX and the proprietary graphics driver, Sauerbraten ran smoothly and was certainly playable -- it usually was usually running at about 200 FPS.
More information on this open-source first person shooter can be found at Sauerbraten.org, where this game's next version should be released in the coming days. On the next page are plenty more screenshots from this latest Sauerbraten build.
