Here's a collection of screenshots to help you decide the best looking open-source game for Linux. The screenshots are a collection of open-source games, albeit far from being an exhaustive of all available OpenGL-powered open-source / free Linux games. The point is to spark a vibrant discussion within the forums to pay tribute to the open-source (or even closed-source) Linux games with the most impressive visuals.
These screenshots on this page were all taken from a NVIDIA GeForce GTX 680 "Kepler" with the proprietary NVIDIA Linux graphics driver. With that said, this article is also a call for requests concerning any GeForce GTX 680 Linux testing you may be interested -- post away in the forums. However, the caveat is that you must be quick with any Linux test requests for this current high-end NVIDIA Kepler GPU.
Since launching the GeForce GTX 680 last month, NVIDIA's Linux team has been waiting on their PR department for "more samples" to send over a GTX 680 for Linux benchmarking, but now their PR department just seems to be playing games; hey, do you have a PCI Express power supply? What platform are you going to test on? Thankfully NVIDIA's Linux graphics driver engineering manager decided we've waited long enough and was kind enough to bypass their PR department. Hardy Doelfel sent overnight a MSI GeForce GTX 680 he personally purchased for use and is letting Phoronix borrow it for some quick Linux tests.
So there's finally some formal Linux benchmarks on the GeForce GTX 680 coming out for the public, but I'll only have this Kepler graphics card for a few days. If there's any Linux users or developers interested in any special test results, Linux dumps, or other information on the GTX 680 post right away in the forums. My proper NVIDIA GeForce GTX 680 Linux review will be out later this week or early next week with the usual thrashing of Unigine Linux tests, OpenCL benchmarks (just this morning new OpenCL test profiles were submitted to OpenBenchmarking.org), thermal results, power consumption, and the other usual metrics from the Phoronix Test Suite comparing the GTX 680 to other AMD/NVIDIA hardware under Ubuntu 12.04.
As shared on Twitter this morning.
The games used for these reference screenshots below were simply the free/open-source games with Phoronix Test Suite / OpenBenchmarking.org test profiles, since it's simply a matter of running SCREENSHOT_INTERVAL=4 phoronix-test-suite benchmark gaming (or similar command) to collect all these screenshots in a fully automated manner, while also pulling in some quick performance metrics (though they're not too interesting aside from the few non-CPU-bound tests, the proper GTX 680 Linux review will have the more interesting OpenGL/OpenCL benchmarks). For now you can also find other GeForce GTX 680 Linux OpenGL results from the community on the Phoronix-owned OpenBenchmarking.org collaborative test infrastructure. In the forums you're also welcome to share screenshots of the many open-source games not listed in this article.
lots of potential with extensive modifications, but also limiting many open-source games is the community-created artwork often leaves a lot to be desired.
just talked about yesterday, but it's the original Enemy Territory game assets paired with a much-improved version of the open-source id Tech 3 engine. ETXReaL drops in an OpenGL 3.2 renderer and many other features for this game that weren't found in engines a decade ago when Enemy Territory made its popular debut.
Nexuiz offered great graphics for the time in which the game was popular back in 2009 and prior, before its demise, but now Xonotic is doing an extremely good job continuing the legacy of Nexuiz and furthering the work on the DarkPlaces engine.
Xonotic is doing great. Xonotic is easily one of the most visually-impressive open-source games available for Linux, Windows, and Mac OS X. Xonotic builds upon the open-source DarkPlaces engine.
iodoom3 and the upstream engine advancement efforts for this open-source id Tech 4 engine seem to have stalled.)
Unigine Heaven isn't open-source and it by itself isn't a game but just a tech demo for the gaming-focused Unigine Engine, it currently holds the title of the most demanding OpenGL Linux binary. If you want to play a game with great (closed-source) graphics on Linux, there is Unigine OilRush as one alternative. Unigine Heaven will likely continue being the most demanding OpenGL Linux test until Valve releases their first Source Engine games for Linux or when Unigine Valley makes its debut. I talked with the CEO of Unigine Corp this morning and he expects to have a build of Valley ready in about one month (though Unigine Engine licensees as of today have development access available; Unigine Corp is also working on some other "big projects" at the moment), so it may be close for who ships first.
Stay tuned for the extensive NVIDIA GeForce GTX 680 Linux review in the coming days, but in the meantime the quality of graphics (or there the lack of) for open-source games can be discussed at length within the forums.
