Workstation-class hardware like NVIDIA Quadro video cards tend to receive a really bad rap in the gaming community because the cost-to-performance ratio is not anywhere near as good as the GeForce cards that are designed and optimized specifically for gaming. Some have even gone to the point of claiming that you cannot play games on NVIDIA Quadro video cards at all! In this article we will examine the gaming performance of Quadro cards to see how they perform in a number of games.
Multiheaded NVIDIA Gaming using Ubuntu 14.04 + KVM
We recently published the article Multi-headed VMWare Gaming Setup where we used VMWare ESXI to run four virtual gaming machines from a single PC. The setup worked great and the article was very popular, but one limitation we found was that NVIDIA GeForce cards cannot be used as passthough devices in VMWare ESXI. We received feedback from some readers that GeForce cards should work in Linux with KVM (Kernel-based Virtual Machine) so we set out to make a GeForce-based multiheaded gaming PC using Ubuntu 14.04 and KVM.
Multi-headed VMWare Gaming Setup
As powerful as modern PCs are, sometimes it feels like a waste having just a single person using a PC at a time. By using various server virtualization technologies including virtual machines and PCI passthrough, we created a multi-headed gaming PC that allows up to four users to game on one physical PC at the same time.
Gaming PC vs. Space Heater Efficiency
Winter is coming, and with the power bills stacking up it may be hard to justify gaming on your ulta-powerful gaming rig. But what if we were to tell you that, watt for watt, your gaming PC produces exactly the same amount of heat as a space heater?
Video Card Performance: 2GB vs 4GB Memory
Similar video cards are often available in versions with more than one memory size. The GeForce GTX 680 is an example, and comes in both 2GB and 4GB variants. With computer components more is often better, but does doubling the memory on a video card like this actually help with game performance – and if so under what circumstances? Although single monitor resolutions only go so high, multi-monitor configurations via NVIDIA Surround or AMD Eyefinity allow for much higher resolutions where larger amounts of video memory may improve performance.
Dedicated PhysX Comparisons
A few years back, Ageia Technologies launched a product designed to help handle the increasingly complex physics calculations which were becoming popular in modern games. They named this product “PhysX”, and it was the worlds first dedicated physics card. Enthusiasts were excited, and many thought that this technology was set to be the next piece of essential hardware for enthusiast systems. We decided to independently test the Nvidia PhysX platform, and share our results.
