Now that Steam is available for Linux, I have finally eliminated my only need for a bare metal install of Windows at home.
I am really enjoying playing some of my long-time favorite games under Linux now, and I hope every day when I open Steam that I will see that Valve has ported Counter Strike: Global Offensive. I'm still waiting though :-)
I did want to share this quick tip for fellow KDE users, however. If haven't already, go to Configure Desktop -> Desktop Effects -> "Advanced" Tab. Find the setting 'Suspend desktop effects for fullscreen windows'. Tick that box.
It really seemed to make a noticeable difference for me. I'm maxing out at 300fps at times under CS:Source now, just as I was under Windows. It made a larger improvement for Serious Sam 3. http://jaysonrowe.blogspot.co.uk/2013/03/gaming-tip-for-kde-users.htmlThree Comments from the above site

For me the difference was also very notable. For Oilrush I only had 5fps more when enabled (40->45) but somehow the output felt much more fluid. (No: I am not saying I see the difference between 40 and 45 fps. I think I got some serious framedrops when compositing was enabled)

For me using Intel graphic drivers with KDE 4.10 stoped working with that option turned on, and I had to disable it, fortunatelly one of the KWin developers made that Kwin script that worked even better for me:

One thing to note about this setting is that if the checkboxes is ticked, you will get screen flashes in Gwenview (and probably other applications) in fullscreen mode. This is because whenever you move the mouse over a button, a tooltip is shown: this tooltip is its own (non fullscreen) window, causing KWin to reenable desktop effects when the tooltip is shown, and disabling them again when the tooltip disappears.
