KWin's developer usually makes smart decisions, but in this case he's dead wrong. Games *need* to be able to change the resolution, period. There shouldn't even be any discussion about it. Claiming otherwise is like saying that you shouldn't be able to change the size of application windows because of some KDE architectural limitation.
I would think that with all the video acceleration technology we have, upscaling or downscaling an image (with appropriate black bars for aspect ratio differences) wouldn't be too much of a performance problem. Video players have been handling full screen playback of arbitrary resolution sources on arbitrary resolution screens for a long time, and in my experience they tend to actually do a better job of scaling than most LCD monitors at non-native resolution. I would actually prefer that programs not be able to change the real display resolution.

Also, some monitors are bad at handling resolutions that are the wrong aspect ratio, stretching it (ugh) instead of black barring it. Doing the scaling in software would allow the user to define what behavior they want for wrong aspect ratio (like the settings for wrong aspect ratio desktop backgrounds), in a standardized way that doesn't require navigating the (usually obnoxious) menu system built into the monitor, which varies from monitor to monitor.
Also, switching in and out of full-screen applications would be quicker without an actual monitor resolution change. It might also be nice if the user had the option (along with the stretch/zoom/scale settings) to allow a non-interactive status bar (with clock, CPU usage, email notifications, etc) to show while an app is fullscreen. The mouse would still be fully captured in the fullscreen app's window (hence the need to the status bar to be non-interactive), but I think it would be nice to actually have some of these things visible even during a fullscreen game. Since the system would already be scaling & black barring to fit an arbitrary window to an arbitrary screen resolution, the (optional) addition of this status bar wouldn't cause usability problems.
Anyway, that's just my opinion as a user and occasional gamer.
Reading this I get cynical.
Can some one tell the kde team, that steam is coming to Linux ?
Or is kde telling me: Hey if you wanna game, don't use kde ?

I do agree to an extent that the problem is somewhat on the game's side as well - I much prefer games that come up with a nice launcher like Trine and Amnesia that allows me to setup my graphics setup before the game actually launches. But casting it off as not being an issue that a DE has to help resolve is very childish IMO.
I personally am glad the both Sam and Ryan are still trying to find ways to push Linux to be an even greater gaming platform.
But why should games have to call the window manager to change the resolution? What's wrong with _NET_WM_FULLSCREEN + xrandr?
Why not to use different screen?
Just like Amiga Operating System do, or for example Open Source version of that system AROS:
one man's downside is the other man's desire.

but that's just me.
and it looks pretty idiotic in 2012, how people, instead of instantly having separate screens with retained ability to use them for separate tasks and drive their displays at native parameters, use ugly clone mode, while also setting display of greater quality on lower mode to accommodate for an inferior one.

that was fucked up too. and the fact that some screensavers's output is screwed in multi-screen still doesn't help.

Just do it like AmigaOS or AROS. Start fullscreen appications in different screens:

The program scans the games in your PC, pops a window with results, after you select game, it will totally rebind what's needed and launch game (it will take care also of left or right handed players and PC, PC+PS2 or PS3 gamepads)...
ANYWAY, i also add some extra stuff when it's running via WINE...
One of the extra tricks is precisely, no matter you simply exit game or game crashed, is to restore the resolution that you were using before launch game ....and i'm talking about true full screen gaming and not virtual desktop in WINE
Till now it's working flawless....you can see some screenshots , info and videos of me playing at http://ajsb.no.sapo.pt
Release is delayed because i'm now testing all games in WINE and have to make sure it works everything correctly also under that....eeerrrrr..."OS".
(Program also takes care of a series of dlloverrides,etc automaticcly w/o you need to mess around with winetricks for each game)
