--- quake screen is 1/4 the size its suposed to be

[MH]

The suggestion of windowed mode was for testing; see if the problem reproduces there too.

why would anyone play in window mode?You will be limited to the refresh rate of the desktop,typically 60 hz on a lcd monitor.Run it in fullscreen to get full fps. Disable vsync. Also match the desktop resolution adding the -fullscreen to the shortcut.
Maybe you do not have a GFX card?

It's a very old question thats repititious but do you have the latest drivers for your gpu? There is a very small chance your using default AMD/Nvidia drivers that are packaged with Windows7 and are really shitty (speaking for AMD experience) and only intended to give basic display support. This will cause the issues your having, buying a video card and just slapping it in there would be the cause without any software/drivers also installed.

Have you went into the GPU's control panel type thing? (AMD has Catalyst / Vision Engine.I dont know anything about nvidia ) and set all your settings to Performance?

and, in the shortcut do this

darkplaces.exe -window -width 1280 -height 1024 (except replace 1280x1024 with your native desktop resolution!)

You can try going into Darkplaces options menu and turn everything off ,try and see if darkplaces mimicing a straight quake client (no flashy shit) will make it run smoother.

Something that might help is telling us what video card you have, is it onboard or addon card? Do you have a Llano APU ? I know that if you do not manually set the GPU's operating frequency you will end up with piss poor performance!

Have you ran a spyware scan? you could have lots of background baddies consuming processor time,unlikely but possible.

you can open darkplaces ,alt tab, push/hold ctrl+shift+escape, find Darkplaces in the processes tab,right click on it, and then Set Priority. Try raising it from Normal to Above Normal or High. DO NOT use Real Time,as that will most likely not end well and might even cause you to freeze up during alt tabs and stuff.

these are shots in the dark, because the problem has too many possibilities at the moment,more info is gonna speed this along

www.cpuid.com ,get cpu-z and run the program,then click the verify button and provide us the link to your verification page.

Okay, I got the window mode to work, and it is centered. However, the window can not be maximized and it is extremely laggy. Heres a screen shot. Thanks

right click darkplaces.exe and create shortcut, then right click that shortcut and go to the target field and it should look like this

In the targetfield, add -window so that it looks something like this D:\Games\DarkPlaces\darkplaces.exe -window click apply/ok/save double click the icon, you should be running in window mode.

Also most engines support alt-enter fullscreen to windowmode hot swapping,try it.
