This week there was a 22-way graphics card test of Metro Redux on Linux using GeForce and Radeon hardware with the latest AMD and NVIDIA proprietary drivers. Today the newest Linux gaming test candidate to look at is the AMD/NVIDIA Linux performance with the latest Unreal Engine 4 demos. In this article is a look at the UE4 Linux performance on AMD and NVIDIA graphics hardware running with Ubuntu.
For your viewing pleasure today are some benchmarks of PC-BSD 10.1 compared to Ubuntu 14.10 and Fedora 21 when testing with both the GCC and LLVM/Clang compilers.
FreeBSD 10.1 was released back in November along with PC-BSD 10.1 and its new TrueOS. It took a bit of time though to get some benchmarks completed of FreeBSD/PC-BSD 10.1 due to running into issues loading the updated OS on a few test systems I frequently use for Linux testing. In particular, disk/SATA issues on multiple systems when booting the PC-BSD 10.1 installer. Fortunately, I came across one of the powerful workhorse systems that played nicely with PC-BSD 10.1
A few days back I wrote about being able to finally get the Metro Redux game benchmarks running in an automated manner under Linux to the point that we're now able to test it with the Phoronix Test Suite. With Metro 2033 Redux and Metro Last Light Redux now running well for our testing purposes, I've carried out performance tests of these two games with twenty-two AMD Radeon and NVIDIA GeForce graphics cards on Linux. Besides looking at the normal FPS result there's also frame latency metrics, power consumption data for each of these graphics cards, performance-per-Watt metrics, and GPU thermal results. If you're wondering what graphics card works best for your needs for OpenGL 4.x Linux gaming, here's an interesting look with the Metro Redux titles that premiered on Steam for Linux back in December.
In upgrading to the new ThinkPad X1 Carbon Broadwell ultrabook, I'm debating whether to switch back to Fedora after having used Ubuntu for a number of years on my main production system after some falling out with a few less then stellar Fedora Core releases back in the day (of course, on test systems, there's plenty of Fedora around here but this is just about deciding on my next main OS for business tasks). In waiting for the new Broadwell ultrabook, I've been running some fresh Ubuntu and Fedora Linux tests on some other laptops/ultrabooks in the office.
With the Linux 3.19 kernel stabilizing nicely, here's a first look at the open-source AMD Radeon graphics performance using this new kernel that will be officially released in the weeks ahead. The Linux 3.18 kernel was compared to the latest Git code of Linux 3.19 for several different AMD Radeon HD series and Rx 200 series graphics cards.
This weekend I got around to trying out the GeForce GTX 970 and GTX 980 "Maxwell" graphics cards with the Linux 3.19 kernel now that there's initial support for these new GPUs via the open-source Nouveau DRM driver.
As part of the big DRM pull request for Linux 3.19, most of the Nouveau driver work was "behind the scenes" with not too much to excite end-users besides initial support for the newer Maxwell GPUs. This support in Linux 3.19 though is just limited to kernel mode-setting with no hardware acceleration being in place for this release.
This comparison is similar to the three-way NVIDIA GeForce graphics card comparison from Monday but just testing the Maxwell-based GeForce GTX 970 and GTX 980 graphics cards while running the latest binary drivers on Windows and Linux. As with the other end-of-2014 Windows vs. Linux benchmarks, Windows 7 Pro x64 with all available system updates was used and on the Linux side was Ubuntu 14.10. The latest NVIDIA Linux driver is the 346.22 driver version while the latest Windows version at the time of testing was the 347.09 driver release.
