putting a very tough machine towards viruses and other malware risks that every PC has got, then you need an antivirus which slows down everything etc ... BootCamp I know is a solution, but not a safe one... what do you think ?
As others have said, this just isn't true on two counts.
First, my main gaming and work machine at home has exactly NO antivirus software on it. It hasn't for 4 years. And this is coming to you from someone who reviews AV and security software for a living, so I get all the good stuff for free. I periodically ghost my system, install the latest and greatest security software, let it do a full scan, determine that the system is still clean, and then Ghost it back to a point when it didn't have any security software installed just to be thorough, since I actively collect viruses for the purposes of testing.
IF you only use your Windows computer for gaming - that is, you don't web surf and you don't check your email, and you keep it up to date with patches, AND if you use a DSL Router/Firewall, your gaming machine will almost certainly remain Virus and malware free. If you have a Mac, use MacOS for all your internet stuff. Just play games in Windows, AND THAT'S IT.
Alernatively, you can install AV software that is light on resources, such as Eset NOD32. It increased the boot time in my test machine by just two seconds, and had no effect on Aces High framerates. NONE.
In short, there are plenty of ways to have safe gaming in Windows. Making ridiculous statements about safe computing that have no basis in fact doesn't help anyone.
