I was using gzdoom and i'm having trouble with open gl. I know it's that because when i disable it everything works perfect. When I have it enabled i can only see half of the screen and chaning the resolution does nothing. I have NVIDIA GeForce 7900 GS with 2gb of ram. Anyone know what I can do?

A 7900 GS video card with 2Gb on board? Are you sure that it is not 256Mb?

Well, anyways ...

When you say that you changed the resolution, where did you change it? In Windows or in GZDoom?
Sometimes it helps, when both these resolutions are the same.

I don't understand what you mean, why can't I have 2 gb of ram with a 7900 gs? the video card is 256mb but i don't have 256mb of ram. It isn't the problem with the resolution but the open gl, because when i disaled it i could see everything just fine.

Well, it's semantics and also technical.

But on to solve your problem:
Have you tried to start GZDoom with the following command line

gzdoom.exe -logfile startup.txt

The resulting file startup.txt (in your GZDoom folder) will tell you how far GZDoom was able to install the required subsystems for it to run. If that does not help you with troubleshooting your system, then I would recommend that you include its contents in a spoiler in your next post.

The only way I know how to start gzdoom is by dropping the wad onto the program. How can I start it with the command line?

Start -> Run or Windows-Key&R

browse for the GZDoom folder, click on gzdoom.exe then click on open
then add -logfile startup.txt to that line.
Make sure there is a space between exe and -logfile.

It should look similar to this:
C:\DOOM\GZDoomR131\gzdoom.exe -logfile startup.txt

of course, the file location on your computer will be different.
