Doing anything tonight? Maybe while you watch the tape delayed closing ceremonies to the 2012 Olympics you'll want to join the PC Perspective Team for a little UT2004 (Unreal Tournament 2004) old school gaming action?
We'll be starting up the game at 8pm ET tonight and you can join me, Josh, Ken and others as we play some team deathmatch, standard DM, CTF, Onslaught and more!
Don't you deserve a little down time? Even if you can't join us on the server, you can watch the live stream of our smack talk at http://pcper.com/live!!
The information below will be filled in a little later this afternoon:
Server: game.pcper.com (18.104.22.168)
Download pack (you MIGHT need): UT2004_MegaPack
You can easily join us by looking in the Internet server browser and finding "PC Perspective" or simply hit the console (~) and type "open game.pcper.com" or "open 22.214.171.124". See you tonight!

After the PC Perspective Podcast on Wednesday night, we played some Unreal Tournament 2004 with many of the PCPer staff and fans. If you missed it - shame on you! Keep an eye on the Upcoming Events schedule on the right hand side here to see when and what we'll play next.
In the meantime, feel free to waste a couple of hours watching us play UT2004 - in the past.

Last year we saw Unreal unviel their Samaritan demo which showed off next generation gaming graphics using three NVIDIA 580 GTX graphics cards in SLI. Epic games showed off realistic hair and cloth physics along with improved lighting, shadows, anti-aliasing, and more bokeh effects than gamers could shake a controller at with their Samaritan demo, and I have to say it was pretty impressive stuff a year ago, and it still is today. What makes this round special is that hardware has advanced such that the Samaritan level graphics can be achieved in real time with a single graphics card, a big leap from last year's required three SLI'd NVIDIA GTX 580s!
The Samaritan demo was shown at this years' GDC 2012 (Games Developers Conference) to be running on a single NVIDIA "Kepler" graphics card in real time, which is pretty exciting. Epic did not state any further details on the upcoming NVIDIA graphics card; however, the knowledge that the single GPU was able to pull off what it took three Fermi cards to do certainly holds promise.
According to GeForce; however, it was not merely the NVIDIA Kepler GPU that made the Samaritan demo on a single GPU possible. The article states that it was the inclusion of NVIDIA's method for anti-aliasing known as FXAA, or Fast Approximate Anti-Aliasing that enabled it. Unlike the popular MSAA option employed by (many of) today's games, FXAA uses much less memory, enabling single graphics cards to avoid being bogged down by memory thrashing. They further state that the reason MSAA is not ideal for the Samaritan demo is because the demo uses deferred shading to provide the "complex, realistic lighting effects that would be otherwise impossible using forward rendering," a method employed by many game engines. The downside to the arguably better lighting in the Samaritan demo is that it requires four times as much memory. This is because the GPU RAM needs to hold four samples per pixel, and the workload is magnified four times in areas of the game where there are multiple intersecting pieces of geometry.
FXAA vs MSAA
They go on to state that without AA turned on, the lighting in the Samaritan demo uses approximately 120 MB of GPU RAM, and with 4x MSAA turned on it uses about 500 MB. That's 500 MB of memory dedicated just to lighting when it could be used to hold more of the level and physics, for example and would require a GPU to swap more data that it should have to (using FXAA). They state that FXAA on the other hand, is a shader based AA method that does not require additional memory, making it "much more performance friendly for deferred renderers such as Samaritan."
Without anti-aliasing, the game world would look much more jagged and not realistic. AA seeks to smooth out the jagged edges, and FXAA enabled Epic to run their Samaritan demo on a single next generation NVIDIA graphics card. Pretty impressive if you ask me, and I'm excited to see game developers roll some of the Samaritan graphical effects into their games. Knowing that Epic Game's engine can be run on a single graphics card implies that this future is all that much closer. More information is available here, and if you have not already seen it the Samaritan demo is shown in the video below.
There are few people in the gaming industry that you simply must pay attention to when they speak. One of them is John Carmack, founder of id Software and a friend of the site, creator of Doom. Another is Epic Games' Tim Sweeney, another pioneer in the field of computer graphics that brought us the magic of Unreal before bringing the rest of the gaming industry the Unreal Engine.
At DICE 2012, a trade show for game developers to demo their wares and learn from each other, Sweeney gave a talk on the future of computing hardware and its future. (You can see the source of my information and slides here at Gamespot.) Many pundits, media and even developers have brought up the idea that the next console generation that we know is coming will be the last - we will have reached the point in our computing capacity that gamers and designers will be comfortable with the quality and realism provided. Forever.
Think about that a moment; has anything ever appeared so obviously crazy? Yet, in a world where gaming has seemed to regress into the handheld spaces of iPhone and iPad, many would have you believe that it is indeed the case. Companies like NVIDIA and AMD that spend billions of dollars developing new high-powered graphics technologies would simply NOT do so anymore and instead focus only on low power. Actually...that is kind of happening with NVIDIA Tegra and AMD's move to APUs, but both claim that the development of leading graphics technology is what allows them to feed the low end - the sub-$100 graphics cards, SoC for phones and tablets and more.
Sweeney started the discussion by teaching everyone a little about human anatomy.
The human eye has been studied quite extensively and the amount of information we know about it would likely surprise. With 120 million monochrome receptors and 5M color, the eye and brain are able to do what even our most advanced cameras are unable to.

There exists a common thought that developing a game is a relaxed experience involving playing all day. Creating games is really a difficult experience; the majority of entry-level jobs consist of creating trees and rocks for the latest Nickelodeon or Disney movie tie-in for 80-hour weeks on end. While there exist some levels of exceptions to that rule and some people who do not mind that lifestyle there is quite a bit of churn in the industry as people simply burn out. Outside the typical distribution chains there exists the independent movement similar to that seen in the 90’s where smaller companies can publish with a much lower overhead now thanks in majority to the internet. For those who wish to develop their own smaller titles there exists many options with Crytek adding one more to the ring; CryENGINE 3 has gone free for non-commercial use with royalty options for commercial applications.
The little engine that cryed is getting the royaltyment
CryENGINE 3, like the UDK, does not include native source code access (full game-code access though) which is to be expected from a modern commercial engine: there are likely quite a few sections of the source code that Crytek cannot legally release to the public because it was written by other individuals and companies. Also as should be expected from an engine like this, regular updates are promised including an update to allow the same DirectX 11 features as was recently patched into Crysis 2 to make your jersey barriers look stunningly lifelike.
