Next april we have an event: FLISOL. It is the Latinoamerican Festival of Free Software Installation. Im planning to move my PC there to show Linux perfomance with games and I would like to hear some recommendations about what games should I show. I was thinking about some free ones and also a couple of commercial demos. What free game do you think looks better (better models, use of shaders, etc)? What commercial demos do you recommend?
My hardware is Radeon HD2600 xt, Celeron 2.8 Ghz and 750 Mb of RAM (Im expecting a donation of 2Gb DDR2 and a Core Duo CPU, but cant be sure if I will have them for april)
Well on the commercial side of things your most demanding game your going to find that looks reasonably modern is Enemy Territory Quake Wars or Quake 4. If you want to have a commercial game that is not a FPS, still the best looking option out there for linux is still Neverwinter Nights. World of Goo for a addictive time killer game.
On the opensource side, best looking IMHO is World of Padman and Alien Arena for FPS. For something other then a FPS then the best looking out there at the moment would have to be Beyond the Red Line demo (at least until Diaspora is released). Other then that everything else out there in linux land looks too dated to "show off".
*edit* Seeing that you have a ATI card you might want to do some research for possible issues trying to run some of these games. Games like Enemy Territory have given ATI cards hissy fits in the past. Not sure what their state is now.
Yo Frankie is buggy as heck, not really a great choice to show off. Also with his current system uningine demo's would crawl unless running at very low resolutions (I'd also say the demo graphics wise is more akin to the original Farcry then Crysis.).
