You don't need special software to run a split screen in Windows. Perhaps you should upgrade from Linux.
I used to play with Linux on some old boxes, but most distros are as bloated as MS these days. Unless you run one of the light builds with limited functionality, you might as well stick to Windows.
No thanks. I happen to like My software without a price tag or mandatory and draconian registration requirements, and My computers to be virus, malware, and adware -free boxen.
Linux is the only way to go for these machines.
We always get the Linux hobbyists crashing the MS threads. I’ll usually counter-troll with the fact that BSD is much more secure than Linux ;-)
