    Primarily the graphics driver. The Windows and Linux versions have hardly anything in common.

      Well this is embarrassing, Intel mesa has been in development for a long time. Seriously, so it takes longer to write a good driver for a single card than to release new cards every now and then?

        Regardless of the results, I was right with my prediction:

        Linux won in the latency department! (At least in OpenArena; it's just too bad that not more benchmarks reveal their frame-latencies...)

          Obviously it's not the OS, since Linux performs every bit as well as windows in video benchmarks when using nvidia cards with the proprietary drivers. The intel open source linux graphics drivers simply do not get the same amount of love as the proprietary windoze graphics drivers.

          Bottom line: If performance is important, use nvidia graphics and run the nvidia binary blob

            What are you talking about?

              Maybe, but I think it has more to do with the fact that OpenGL was not designed for modern hardware. Also older Intel GPU's do perform well compared to Windows. So it's really (imo) a matter of the hardware not being appropriate for the software stack it runs. That's been true of OpenGL for a long time.

                Basically, in a nutshell, there are two companies in particular who make GPU drivers that are 100% dedicated to pushing MS, and 100% dedicated to making sure Linux doesn't encroach on any of MS's established territory.

                The problem with Linux is that it's largely ISA-independent, as Android showed, and there's no way Intel is going to get behind that for consumer devices. Servers, yes. Consumer devices, hell no. That's why Intel started pushing all that Surface Pro crap and basically told Android to f off.

                    We have already given up on OpenGL for Linux. Waiting for Vulcan.

                      This attitude is ok for AAA games.
                      But elsewhere not all other applications or games from smaller studios are gonna jump to Vulkan. OpenGL will live on despite it's problems, that's why it's important for Intel and AMD to get their openGL in order.
