Video games supporting hardware acceleration by PhysX can be accelerated by either a PhysX PPU or a CUDA-enabled GeForce GPU, thus offloading physics calculations from the CPU allowing it to perform other tasks instead, potentially resulting in a smoother gaming experience.
So your GPU is utilized to compute physics models, using variables such as mass, velocity, friction and wind resistance. It can simulate and predict effects under different conditions that would approximate what happens in real life or in a fantasy world and then translate that into video games.
Most GeForce series 8 and higher graphics cards can handle CUDA. And as such Series 8, 9 and GTX 200 graphics cards can be utilized for NVIDIA PhysX processing.
Once once you start using this feature you will forfeit some of the overall performance of the GPU. On your average GPU this is roughly 10 to 15%
That's why in the future you could use your older CUDA ready graphics card as an add-on, and use it as a physics card while your shiny new graphics card can render the game. The idea, although not definitely new, is an interesting one.
This month a new patch is distributed for two new games as well, Sacred 2 Fallen Angel (RPG) and Star Tales (social networking game). We have some videos from Sacred 2 Fallen Angel and Star Tales showing off PhysX.
Mind you that the videos are provided by NVIDIA, thus are showing the cherry picked effects and have a logo or 50 too much in them.
Above you can see Star Tales. What you need to focus on is the cloth simulations. These are GPU Physics based.
So while it is hard to explain exactly what PhysX can do in your games I will give you a few examples. Imagine cloth or flags moving fluently, dynamically created force fields with changing geometry, when you shoot at stuff, loads of debris.
We test and review the Gigabyte GeForce GTX 780 WindForce 3x OC edition. The graphics card comes witha factory overclock and the new WindForce 3X 2 Slot 450W fan sink with Triangle Cool fans, as they like to cool it. That would be three silent 80mm fans. Overall the card is almost as fast as a GeForce GTX Titan, 100% cool and 100% silent. We test the product with the hottest games like Metro: Last light, Battlefield 3, Sleeping Dogs, Far Cry 3, Medal of Honor Warfighter, Hitman Absolution and many more.
GeForce GTX 780 SLI and Multi monitor review
We review the GeForce GTX 780 SLI and also do a SurroundView session with three monitors. The boards used are reference from NVIDIA. Over the next few pages we'll tell you a bit about multi-GPU gaming, the challenges, the requirements and of course a nice tasty benchmark session with the latest games. We'll have a peek at temperatures and power consumption of the GeForce GTX Titan cards in 2-way SLI mode to monitor it's generated performance.
GeForce GTX 780 review
We test and review the GeForce GTX 780. The GeForce GTX 780 is NVIDIAs all new high-end graphics card based in their Flagship product, the GTX Titan. This means it is based on the GK110 GPU and has an whopping 7.1 Billion transistors. That makes it a nice chunk faster opposed to the GeForce GTX 680 GPU. We test the product with the hottest games like Metro: Last light, Battlefield 3, Sleeping Dogs, Far Cry 3, Medal of Honor Warfighter, Hitman Absolution and many more.
Gigabyte GeForce GTX 650 Ti Boost OC WindForce 2X review
In this article we review the Gigabyte GeForce GTX 650 Ti Boost OC WindForce 2X with that OC for a factory tweak and the Windforce indicating a silent yet powerful two fan cooling solution. The product is customized with a new PCB, cooling and a few tweaks, it has 2GB of memory with both that memory and the core base-clock slightly overclocked. An tasty product at an interesting price in the lower segment of the mainstream market.
