Gaming and window compositing problems [SOLVED]

Greetings,
I suffer from frame rate problems when compositing is enabled while playing games.
On this computer, they worked side by side without too many problems when I used KDE (the desktop effects were not automatically disabled by KDE either).
Now I use Xfce and have enjoyed it so far except for the problem mentioned earlier.

I have a NVIDIA graphics card and tried some ideas out at this article but with no luck so far.
I remember changing KDE's texture filter to "nearest" and I think that helped but I am not completely sure.

Are there some settings in Xfce or NVIDIA I should change? Or should I do something else all together?

Perhaps there is a throttling package or something similar to that?

The only solution I've found for reliable nvidia gaming, is to disable composite in xorg.conf - so that's your last resort

I have an idea that I will be researching around for more information on.
In KDE, I remember that Opengl was used in a setting instead of NVIDIA's X Rendering (or was it direct rendering...).

With my minor knowledge of graphics cards and rendering, I came up with this:
Opengl's memory management was used in KDE, so it explains how my computer was able to handle both compositing and graphic intensive games. And that X Rendering is not good at(or has any ability) managing memory. So I must find a way for NVIDIA to only use Opengl.

Please correct me if I am making the wrong conclusion!

EDIT: Looking at the NVIDIA server settings again, it looks like it already uses Opengl.
Reading more from many forums, it looks like Xfce's compositing uses EXA for rendering confusing the situation just a little more.

I just tried Compiz Fusion (which uses Opengl) and compositing with games runs perfectly fine.
I am 99% sure the problem was caused be Xfce's window manager Xfwm using EXA for rendering.
So to you search engine users who may find this post, replace the window manager with one that uses Opengl.
Farewell.

I found this little treat on the wiki about two months ago. https://wiki.archlinux.org/index.php/Gaming

Except nothing there really helps for this topic (maybe separate X server, but that's quite overkill for what the OP describes).

Arch Linux
