X choppy rendering - renders in parts

[ibanex22]

Hi, I have noticed that my X server seems to render things in steps instead of at one whole time. Lightweight apps (such as XTerm) will pop up all at once and look perfect but sometimes heavier app will render parts first, then a split second later render the other parts. Also some when desktop switching, an app that is below one will render first for a split second, then the other one will come up.

I have the drivers from NVidia, direct rendering enabled, and what I think are most of the optimizations in my xorg.conf. I was wondering if anyone could shed some light on this or possibly give me some tips to make things load, then render all in one. I would sacrifice a little load time for the rendering.

Thanks!

Modes ( Resolutions ) are missing. Add supported modes in Depth 24 section.

thanks for the reply. My resolution was working the same before, but I added mine anyways. still choppy

I missed Refresh Rates. Those are missing too.

EndSection

Check your Monitor's Manual for supported HorizSync and VertRefresh rates and edit code accordingly.

Ah that's probably it but I cant seem to get the max. Do I need to specify something?

HorizSync 30-81
VertRefresh 56-75

Are these supported rates?
Max VertRefresh usually higher than max HorizSync limit.
Try this:

	HorizSync    30-81
	VertRefresh  56-100

[ibanex22]

Those are right from the manual. It also says 1680x1050@60Hz is optimal which is what I am at right now :/ . Should I just stick with this? Maybe it's not my refresh rate that is the issue.

[devils casper]

We always try to set correct Modes and Refresh Rates first. In case those couldn't solve the problem, Video Driver is the next.
How did you install nVidia Driver?
Try Higher Refresh rates once. If anything goes wrong, you can switch back to lower rates easily.

[ibanex22]

The drivers first were set by emergeing nvidia-drivers and doing whatever the Gentoo wiki told me to do. I noticed an outdate of the drivers with nvidia-settings so I just installed the latest from the Nvidia site which didn't fix it. If it is of any help, I'm on Fluxbox... I don't know how the X server commnuncates with my window manager and if it is to blame.

How fast is your processor? Is your Driver option in your graphics card's Device section set to "nv" or to "nvidia"? Is this X server remote or local?
