TechREACTION.net is at PAX East tonight for the Nvidia Launch Event where they will be officially announcing the new GTX 480 and GTX 470 series of graphics cards. Many of the details of these new GPU’s have already leaked out, but tonight will we know what is true and what is false. Hopefully there will be a few surprises in store, but to find out you’ll want to keep track of this live blog from 6:00PM EST and on as we give you live updates from the launch event!

Keep your eyes peeled on this page, be sure to digg and retweet, and we’ll see you at PAX!

Nvidia Fermi Launch Event Updates:

6:08PM – Waiting for show to begin…fans going crazy with noise makers.

6:11PM – “Please take your seats, show will start in 1 minute”

6:13PM – Drew Henry (General Manager, GeForce GPU’s) is coming on stage to begin the event…

6:14PM – Drew is telling everyone how awesome us gamers and Bostonians are.

6:15PM -  Nvidia snuggies are confirmed for giveaway….lol

6:17Pm – Here comes the spin, discussing why Fermi was delayed.  “We wanted to make something great for gamers”.

6:19PM – Showing off Fermi.  “The GeForce GTX480…is something you are really going to be delighted with.”

6:20PM – ” It’s the most complicated GPU we have ever built.”  3 Billion transistors.

6:21PM – “And we have the GeForce GTX470..it’s little brother, also a great gaming GPU.”

6:22PM – Performance Numbers: GTX480 compared to 285, “sometimes more than 2x performance, no less than 1.5x”

6:23PM – “2x performance in overall gaming is cool, but it’s not just a GPU for gaming.”  “We’ve invested a lot in physics, to allow you to blow things up. “  “Up to 2.5x the gpu physx processing performance of the last generation”

6:24PM – “Real-time interactive ray tracing…”  Is this a Larrabee conference?

6:25PM – New Nvidia “Crank that S#it up!” t-shirts.

6:26PM – This next part is in 3D.  Now he’s talking about he feels the PC can lead the industry in 3D, with 3D VISION.

6:27PM – EA’s Gordon Van Dyke here now, showing off BF:BC2 in 3D.  Showing how they were able to incorporate 3D VISION into their latest hit.

6:28PM – Showing BC2 in Nvidia 3D Surround, that’s three screens, full 3D.  Looks VERY impressive actually.

6:29PM – Showing BC2 jungle fight scene with the militants when you hold out in the shack.  Again, very impressive, but the full surround sound is certainly adding to the effect.

6:30PM – Basically 3D Vision Surroind is 3D Vision meets ATI’s Eyefinity.

6:31PM – Going to show WoW in 3D Vision now.  Allll of the nerds are going berzerk.

6:32PM – Little LOL as the frame rates totally suck as they are in flight mode in WoW in 3D Vision Surround.  Not sure what that’s about…but they say it’s fresh support, just added, so perhaps it’s still in “beta”.

6:33PM  – Jesse Addly (?) from EA.  Does Tech Dev at EA for the PC platform.  So, engine development.  Going to talk about Need For Speed now, also in 3D Vision Surround.

6:34PM – Ooooh, going to show off real-time ray tracing, with cars in Need For Speed.  It’s in 2D, but it’s showing you interactive Ray Tracing, in what looks like a few frames under 30fps.  It’s allowing you to customize a ray traced car in game.

6:36PM – This is a downloadable app with the entire NFS Garage inside, you can customize and collect your cars, add your creations to in-game NFS.

6:37PM – Apparently this app will ship with every GTX480 and GTX470, so a bundled app, but not a full game by any means.  Interesting.

6:38PM -  “Working with the guys in the game industry is really important for us.”  “Often times what we’ll do is put together technology demonstrations to show what they can do with our technology in their game”

6:39PM  – Next up “This is what we call Super Sonic Sled”.  This is a full game they are going to include with every GeForce card.  This is the rocket sled demo everyone saw a few weeks ago.  It’s in full 3D Vision Surround.  All the latest DX11 technology and lots of tesselation.

6:40PM – Showing off different parts of the game world they created.  Showing off the rocket sled, Barney (the sled driver), the millions of pieces of the bridge that gets destroyed.  Showing the details in wire frame as well, so the viewers have an idea of the complexity.

6:42PM – They are using the chicken gun that they have implemented in the game to blow off pieces of the rocket sled, which destroys the sled as he takes off.

6:45PM – Added a million particles to the bridge and blew it up to show the capability of the GPU’s Physx processing.

6:47PM – Next up Metro 2033.  Louis Giglioti (?) from THQ to discuss.

6:48PM – “Let’s see the game…”  Metro 2033 running in full 3D Vision Surround.  Lot’s of game background talk, the author, the story, blah blah..go read the review.

6:53PM – Ok, that demo is finally over.  Just a game promo essentially.

6:53PM – “With this generation architecture, we have them in full production, full launch today, the reviews will be posted in about 10 mins. ” And they will be in stores in about 14 days.

6:54PM – Something with green nailpolish on their 3d glasses just won a GTX 480.  Now they are tossing out tosses. I just punched out some nerd to get one!  “Sucks to be you nerd”  j/k…or am I?

6:55PM -  Show is clearing out, it appears it might already be over, even though it hasn’t been officially stated yet.

6:56PM – It’s over, good night.
