#2167351 Completely Path-Traced Version of Quake 2 Using RTX Created

Posted by That_Guy on Yesterday, 12:57 AM


For those of you with NVIDIA RTX graphics cards, there is now another game that takes advantage of the GPU's RT Cores, it just might look a little old. Q2VKPT is a proof-of-concept project that has completely replaced the original graphics code of Quake II with a path tracing solution called VKPT. Rasterization is only used for rendering the UI, so everything else uses ray tracing and path tracing. Path tracing and ray tracing are different, as the FAQ at the first link explains, as ray tracing is a primitive operation that does not produce realistic images, while path tracing is the light transport algorithm here that does create the image.

To make this possible, a number of technologies are being used, including the RT cores of NVIDIA's Turing-based GPUs, which are being accessed with the VK_NV_ray_tracing extension. As you may have guessed by that extension name, this is using the Vulkan API instead of DirectX, and so can be run on Linux as well as Windows, provided you have an RTX graphics card. In addition to utilizing the RT cores, an adaptive temporal filter is also in place, which will track changes to the light transport path so previously computed information can be reused, instead of new computations being done. Many modern games use temporal filtering in a similar way, but look only to the image space instead of the high-dimensional space used here.

Even if you do not have an RTX graphics card, you may still want to check out the source links as this proof-of-concept could be demonstrating some of what we will see in the future of games. If you do have an RTX card though, you can also download and try he game out for yourself.

Any particular reason?

i  upgrade just to upgrade and i find myself losing interest in gaming so whats the point.   


I agree. I caught myself thinking - "ok, so i am going to buy a new Gsync screen coupled with 980 Ti, waste $1.5k and then what? Run a few games, make sure there is no screen tearing and then use the machine once a week to do my job-related tasks?" Most of the games i occasionaly revisit run smoothly even on my current GTX 670... So whats the point...

#2113449 EVE Online Battle Causes $300K USD in Damages!

Posted by That_Guy on 30 January 2014 - 02:37 PM

That's why I don't spend real money in games.

Nobody talks about real-world money losses. EVE has an in-game gametime payment option called PLEX (pilot license extension). Prices on those fluctuate but 1 PLEX is always equal to i believe 15$ (or subscription month). Therefore it is quite easy to translate in-game currency losses into real-world money. Let's say if 1 PLEX costs 450 million ISK on the market and i lost a 900 million ship then i could say i've lost 30$ (but not necessarily 30$ that i invested into the game). Some can make billions a day in in-game currency thus eliminating the need for ANY real world money investments (EVEN SUBSCRIPTION).


So, when they say 300.000$ they mean that 100 titans @ 3000$ each was destroyed in that battle. 


I hope that's what you meant :P I myself am very opposed to throwing money into games even though i can afford it. I always felt like flying a billion fitted ship is more fun if i spent time farming ISK for it or building it myself :P

New ARAM mode made it fun to play again, for me at least. Really loving the quick start and constant team-fight. Plus, its a great way to learn new champs that yo never played before.
