Has main stream linux abandoned running games?

I think the majority of your problems are indeed caused by trying to do things the ‘old-fashioned’ way.
As linux has evolved things moved around and it sounds like most things you are trying to do became obsolete.

I’d say with 99% certainty that your hardware itself is not to blame, I have a core 2 duo combined with a NVIDIA videocard myself and it runs anything I throw at it. (On both Vista and openSUSE 11.1). Even my quad-core desktop has no problems with anything. (WinXP and openSUSE 11.1).
In the other thread you posted I’ve posted a reaction with how to install the NVIDIA drivers, so let’s try to keep that that discussion there.

Where else can I download the video card driver that you mention of?
They can be found on NVIDIA - Driversite (Japanese) but I would HIGHLY recommend not to download them directly and attempting a manual install. I have a feeling that you might run into problems again as your knowledge seems a bit behind on times, instead use the way I described in the other thread.
If you do want to attempt a manual install please do so by following the steps described on: NVIDIA - openSUSE. (Just print them out or have them at hand on a secondary computer)

many of them are 3D games written by nvidia themself
NVIDIA doesn’t actually write any games. Their logo is just often in the startup screen of games because they have been optimised to run on NVIDIA videocards.

I am just a photographer/graphic illustrator by profession with minimal college education only obtaining a BSEE in Japan for entirely different subject matter quite far and crude from BSCS Hon. English is my forth language and perhaps you have difficulties understanding my broken English.
Well I’m a bit of anime addict and if the english in anime sketches a somewhat realistic situation then I must say that I am impressed at your knowledge of the english language! (I’m only bilingual, unless you count my very basic Japanese / German knowledge)
Just that like I said before… you’ve a tendency to post too much at once :wink:

Now as a final word of advice, don’t try to install anything manually without having the following things first:

[ol][li]Enable the packman repository (have to do this only once)[list=1][]Go to YaST software management[]Menu: Configuration[]Menu option: Repositories[]Add (button)[]From the list select community repositories[]Next (button)[]Mark the Packman Repository option[]Ok (button)[]Ok (button)[/ol]Those steps enable the packman repository that contains 90% of the software most people want.[/li]
[li]Everytime you want to install a program[ol][
]Go to YaST software management first and search for what you’d like to install there.[/li](Searching for ‘quake’ for example returns the quake 3 demo (3D shooter))[li]Search for it on: webpin which returns a bunch of one click installers[*]Do what you wanted to do in the first place, compiling the program yourself. [/li]And if you run into problems ask for help on this forum :)[/ol][/list]
My apologies if any of this sounds like down-talking to you, it wasn’t my intention.
