Using Linux, I don't seem to have any speed issues. Using Windows, it is slightly faster but not by much. I run a dual boot machine. I used to boot Windows to run steam and play steam based games. Now I run them all in Linux. Some times I'll reboot to run Company of Heroes with Windows..... its a little glitchy with Linux.
We're rebels. We're misfits. But mostly, we're software liberators. And we're very, very good at what we do. We have to be. Lots of developers work with open source, but only a tiny fraction of those are good enough to get software that was designed for one platform to work on another one. We invented CrossOver software - a unique approach to cross-platform compatibility that does not require dual-boot or another OS license. We launched PortJump to help app and game developers broaden their market beyond Windows® users. And we launched ExecMode to help organizations solve really ugly technical challenges.
